Top 10 Virtualization Technology Companies

Top 10 Virtualization Technology Companies

Any discussion of virtualization typically ends in clicking glasses and high fives, heated discussions or slap fights, but it almost always begins with VMware, as does this list. These top 10 virtualization vendors deliver the best virtualization software solutions on the market today. Virtualization technology is all the rage, but which product is right for your organization? Learn the 10 virtualization vendors that deliver the best software solutions. You might not require every bit and byte of programming they're composed of, but you'll rejoice at the components of their feature sets when you need them. These solutions scale from a few virtual machines that host a handful of Web sites, virtual desktops or intranet services all the way up to tens of thousands of virtual machines serving millions of Internet users. Virtualization and related cloud services account for an estimated 40 percent of all hosted services. If you don't know all the names on this list, it's time for an introduction.

1. VMware

Find a major data center anywhere in the world that doesn't use VMware, and then pat yourself on the back because you've found one of the few. VMware dominates the server virtualization market. Its domination doesn't stop with its commercial product, vSphere. VMware also dominates the desktop-level virtualization market and perhaps even the free server virtualization market with its VMware Server product. VMware remains in the dominant spot due to its innovations, strategic partnerships and rock-solid products.

2. Citrix

Citrix was once the lone wolf of application virtualization, but now it also owns the world's most-used cloud vendor software: Xen (the basis for its commercial XenServer). Amazon uses Xen for its Elastic Compute Cloud (EC2) services. So do Rackspace, Carpathia, SoftLayer and 1and1 for their cloud offerings. On the corporate side, you're in good company with Bechtel, SAP and TESCO.

3. Oracle

If Oracle's world domination of the enterprise database server market doesn't impress you, its acquisition of Sun Microsystems now makes it an impressive virtualization player. Additionally, Oracle owns an operating system (Sun Solaris), multiple virtualization software solutions (Solaris Zones, LDoms and xVM) and server hardware (SPARC). What happens when you pit an unstoppable force (Oracle) against an immovable object (the Data Center)? You get the Oracle-centered Data Center.

4. Microsoft

Microsoft came up with the only non-Linux hypervisor, Hyper-V, to compete in a tight server virtualization market that VMware currently dominates. Not easily outdone in the data center space, Microsoft offers attractive licensing for its Hyper-V product and the operating systems that live on it. For all Microsoft shops, Hyper-V is a competitive solution. And, for those who have used Microsoft's Virtual PC product, virtual machines migrate to Hyper-V quite nicely.

5. Red Hat

For the past 15 years, everyone has recognized Red Hat as an industry leader and open source champion. Hailed as the most successful open source company, Red Hat entered the world of virtualization in 2008 when it purchased Qumranet and with it, its own virtual solution: KVM and SPICE (Simple Protocol for Independent Computing Environment). Red Hat released the SPICE protocol as open source in December 2009.

6. Amazon

Amazon's Elastic Compute Cloud (EC2) is the industry standard virtualization platform. Ubuntu's Cloud Server supports seamless integration with Amazon's EC2 services. EngineYard's Ruby applicationservices leverage Amazon's cloud as well.

7. Google

When you think of Google, virtualization might not make the top of the list of things that come to mind, but its Google Apps, AppEngine and extensive Business Services list demonstrates how it has embraced cloud-oriented services.

8. Virtual Bridges

Virtual Bridges is the company that invented what's now known as virtual desktop infrastructure or VDI. Its VERDE product allows companies to deploy Windows and Linux Desktops from any 32-bit or 64-bit Linux server infrastructure running kernel 2.6 or above. To learn more about this Desktop-as-a-Managed Service, download the VERDE whitepaper.

9. Proxmox

Proxmox is a free, open source server virtualization product with a unique twist: It provides two virtualization solutions. It provides a full virtualization solution with Kernel-based Virtual Machine (KVM) and a container-based solution, OpenVZ.

10. Parallels

Parallels uses its open source OpenVZ project, mentioned above, for its commercial hosting product for Linux virtual private servers. High density and low cost are the two keywords you'll hear when experiencing a Parallels-based hosting solution. These are the two main reasons why the world's largest hosting companies choose Parallels. But, the innovation doesn't stop at Linux containerized virtual hosting. Parallels has also developed a containerized Windows platform to maximize the number of Windows hosts for a given amount of hardware.

Server buying tips


Server buying tips

Purchasing a server for any business is a very big decision, and if not done properly, can reduce productivity or cause loss of money in the business. Below is information and help for what to look out for when purchasing a computer server. It is important to also note that every business is unique and may require more or less of what is listed below.  

New vs. Used

Purchasing a new or used server or server equipment can be a method of saving the company additional money; however, it can cause lost money if that hardware or server does not meet the company's needs. When looking at purchasing a used main server or file server for a computer network, ensure that the server is going to meet the company's needs as far as performance and reliability. Unless the perfect used solution is found, we highly recommend purchasing a new main server, file server, network server or database server, as it has the latest hardware innovations as well as have a warranty, which allows parts to be replaced or repaired within a short period of time, keeping the network up and running.

However, other servers such as a print server or hardware such as a router or firewall can be purchased as used and meet most companies' needs.

What to look for

When purchasing a server, it is important that either the company or the network administrator consider the following:

Case and rack

When looking at the case or rack, look at the expandability as well as the accessibility of hardware. Determine how may drive bays if any are available as far as what drive bays (5.25" vs. 3.5") or available hard drive bays in the computer.

Drives

Hard drive

  • The available amount of disk space on the server can be an important consideration especially if the server is going to be a file or network server. Consider the space requirements needed for the operating system, applications, tools, utilities, web pages, files, and user settings.
  • When also looking at the hard drive, it is important to look at the hard drive interface. The majority of all servers today use either SATA or SCSI hard drives.

CD-ROM

  • CD-ROM is not a critical item for most servers as it is usually only used to install additional software onto the server.

Backup

For all networks, backup is and should be an important consideration. Most companies need important data, such as company or customer related information, backed up on a daily basis. When looking at a backup solution, consider the following.

  • Is backup available with the server, if so what is it?
  • If available, what is the capacity of the medium?
  • If available, how fast is the medium (how long does it take to backup 4 gig for example).

Memory

Memory is and has always been an important consideration when looking at purchasing a server or any computer. Determine the amount of memory included in the server as well as verify if that memory can be upgraded in the future. It is recommended that at least 512MB of Memory be installed into the network or file server.

Network card

With the increase with more than one computer in the house and with broad band solutions, sometimes requiring a network card a network card is becoming an important consideration when purchasing a computer. Network cards allow users to connect to other computers and have small networks in their home or office. This allows for data transfer, file sharing, Internet connection sharing, printer sharing and other helpful uses.

Operating system

When setting up a new network verify the operating system or networking software is included with the server. If no operating system is included with the computer, verify what operating systems have been tested with the computer. For example: Novell, Windows NT, Windows 2000, Unix, Solaris, Linux, SCO... Etc.

It is also important that when setting up a network that the operating systems being installed or included is something that the network administrator is familiar with or requires for compatibility with other software.

Power

For large networks or servers, power may be an important consideration. Look at the available amount of power supplies as well as the capacity of each of the power supplies.

Additionally, if you believe power may be an issue in the future, look at the availability of upgrading or adding additional power supplies to the server.

Processor

The computer processor and the amount of processors the computer can support is one of the most important considerations when looking at a server. When looking at the server, consider the following:

  • What processor is included? (Intel Pentium, Intel Xeon, Digital or other).
  • How many processors can the server support? (2, 4, 8 or more).

Brand of computer

When looking at purchasing any brand of computer you will hear good and bad stories. Regardless if the story is good or bad, these stories are always based on the experience of that user. While it may be true that the user had a bad or terrible experience with that computer, all computer manufactures have had users who have had a bad experience and there is no such thing as a bad or perfect computer manufacturer. Below is a listing of various things to consider when purchasing a computer and in some cases how to tell the good from the bad.

Documentation

Verify if the server or networking device comes included with documentation. While most hardware, such as a router or hub, will not require documentation for most network administrators it is important that a server be included with some documentation that help with configuring the server or server components. This comes in real helpful for configuring jumpers and upgrade information.

Location

We use location as a description to describe different topics. First, what is the location of where the network hardware or server is purchased: If the network hardware or server is purchased at a local retail store, can the network hardware or server be returned if unsatisfactory or incompatible to that store? If the network hardware or server is purchased through mail order or directly through the computer manufacturer or reseller, where can the network hardware or server be returned if unsatisfactory or incompatible?

Second, can the store location of where the network hardware or server was purchased service the purchased product? If not, where is the closest location to where it can be serviced?

Third, if the network hardware or server is purchased directly from the computer manufacturer and is shipped through mail, how is it shipped? What is the time period for the network hardware or server to arrive to your destination? What happens if the network hardware or server is damaged during shipping?

Return

Verify you can get money refund for the network hardware or server. Many computer manufacturers will not refund your money but instead may offer an exchange for another product of similar qualities. Verify with the manufacturer or the reseller what their return, refund, and exchange policy is.

Service

Service is an important consideration to look at when looking to purchase a networking hardware or a server. The service is how many companies describe the repair of the device purchased if it's to become unusable. Below is a listing of some examples of services.

  1. Is the service onsite, meaning a technician will come to your location to replace or fix a bad component. If the service is onsite, is it for the complete time of the warranty? Finally, if onsite is offered because it is likely this will be a network critical component, what is the time frame for the repair to be completed and can it be done 7 days a week 24 hours a day?
  2. If onsite is not offered, what is and for how long?
  3. Are their local service centers that may stock the potentially bad part or stock parts that can be used to exchange the part that has gone bad? If yes, what are their hours and availability?

Support

Manufacturer support for most companies is an important consideration as if an issue arises with the computer you must be able to contact a support representative. Things to consider when looking at the support options of a computer are listed below.

  1. Is support open 24 hours, 7 days a week? If not, what are the hours, or is a paging service available?
  2. Is support open on holidays? If not, what days are it closed, and the days that they are closed is a paging service available?
  3. What support options are available? Phone? E-mail? Web? Chat? Pager?

Upgrade

While this option may not be considered at first when purchasing a computer, it is an important consideration. Below is a listing of different options to look for when looking to upgrade a computer.

  1. What can be upgraded in the computer? RAM? CPU? Hard Drive? Video Card? If available to upgrade, what are the maximum amounts or is it specified within documentation provided with the computer?
  2. Does the computer have on-board hardware such as an on-board Network or SCSI? If yes, can these be disabled with a jumper or through CMOS. This is important as many computer will disable the device when a new device is added. However, this does not always work and may cause future issues. Ensure it can be disabled and that it is not a device that auto-disables.

Warranty

Finally, what warranty is offered by the computer manufacturer? How long is the warranty? Does the warranty cover both hardware and software issues? 

What To Consider When Buying a New PC or Server For Your Company



What To Consider When Buying a New PC or Server For Your Company

You've decided to purchase a new personal computer (PC) or server for your office. Perhaps you've hired a new employee who needs a workstation, or you've decided it's time to get a server so you can have one central location for your data. Whatever the case, one question haunts you: Where do you start?

There are so many choices, it can be a full-time job to sift through all of the information and determine what you need. Whether purchasing a PC or server, there are two main options: Buy a "white box" (also known as a clone, or a "generic version") or buy a brand name.

While each has pros and cons, it is widely known that clone computers are harder to support and require more time to repair than brand name computers. It's one thing if you like to tinker and have all the time in the world to configure a computer, but it is another thing to run one's business on someone else's hobby.

Of course, determining which brand name computer to purchase is another matter. Some helpful guides to check out are Consumer Reports and Computer Shopper magazine at your local newsstand for reviews on various brand names.

Since every business' specific requirements are different, no single article can tell you what to get for your office. However, we can provide tips to get you started in the right direction. For specific recommendations regarding what hardware and software you might need, seek advice from a professional IT consulting firm.

Important Considerations for PC and Server Purchases

  1. Find a reputable brand name which uses reputable hardware manufacturers.
    Most brand name manufacturers come with great warranties, online support resources and service agreements. While you hope you won't need them, it's nice to know there are provisions for service and replacement parts if necessary.

  2. Flexibility.
    As your company grows, you will likely need to expand your network and capabilities. Find out how flexible the products are and if they will be able to grow with you and your business.

  3. Compatibility.
    How will your new PC or server integrate with existing hardware, software, etc? You may discover you need to invest more than you thought you would initially. Don't be afraid of this conclusion. It is better to know now what you need to grow your business than to find out later that what you hoped to be able to do is stunted because of insufficient hardware.

When do I need a server?

Knowing when it's time to buy a new PC is fairly cut and dry. Knowing when/if you need a server can be harder to determine. Mike Carpenter, Director of IT Services, at Corporate Computer Services points out some indicators that suggest you may need a server:

  • Do you have more than five workstations?
  • Are your backup's dependent upon daily intervention?
  • Are your critical Operating System and antivirus updates dependant upon daily intervention?
  • Are your critical files located in different locations of your network?
  • When you make network changes do you need to do this at each workstation?
  • Do you want your files/data to be secure and only accessible to those whom you specifiy?

According to Kim Komando, host of the largest talk-radio show about computers and the Internet, it's time for a server when you answer "yes" to any of the following questions:

  • Are there snags in your workflow?
  • Do two or more people use the same database?
  • Would operations slow down or stop, even for a small amount of time, if one computer were to crash?
  • Do you or your employees need access to email and files on the road?

As for the advantages of a server, she highlights the following:

  • Disaster Recovery, Antivirus, Email, User Administration, Data and Network Security can all be centrally managed.This makes network administration easier and thereby less expensive to maintain.

  • The server can be the primary backup point. Instead of burning data files on disks, you can quickly move them across the network.

  • You can host your own e-mail. This allows you to have your own domain and unique e-mail addresses. An e-mail address of john.doe@johndoeinsurance.com is more professional than john.doe.insurance@igotafreeinternetaccount.com. Also, most e-mail software allows you to maintain network-wide address books, mailing lists and calendars.

  • You gain more control over all that annoying spam. An employee who opens an infected attachment could easily infect all of your computers. But when hosting your own e-mail, you can filter it so that the good stuff comes in and most of the bad stays out.

  • You gain a higher level of security. By requiring computer users to log in and authenticate on a domain, the server dictates who has access to what.

  • You can deploy new software applications more easily through a network. You also can standardize your applications and versions, and make better use of the software you have.

Now that you know whether you need a PC, server, or both, it's time to address hardware and software considerations for each. It is important to understand what functions you need your computer or server to perform in order to determine which hardware and software you need.

Hardware and Software Considerations for PCs

You may see a brand name PC advertised on TV or in the mail with a price that seems too good to be true. It probably is. Most likely, the price does not include necessary hardware and software configured for a networked office environment.

Below is a list of some basic things to consider when purchasing a workstation (PC):

  • Is this for home or the office?
  • What role will this workstation (PC) serve?
  • Are the tasks to be completed by the workstation (PC) basic or complicated?
  • What operating system do you need?
  • Depending on its role and purpose you will need to select the appropriate hard drive size, ram, video card and monitor size.
  • If your computer is to be part of a network, you will need to make sure it has a network card.
  • What tasks do you need to perform: word processing, spreadsheet calculations, photo editing?
  • At what level do you need to do the above tasks, basic or advanced? This might determine the specific application you need.
  • There are many other accessories and peripherals that require some consideration such as:
    • Do you need to burn/view CD's or DVD's?
    • Do you need to be able to scan or print from this workstation(PC)?
    • Do you need to connect to a financial institute? You may need a modem.
    • Do you need to connect more than one monitor to this workstation (PC)?

For clarification of some of the terms listed above, please check out www.whatis.com.

The definitions you will read in the following sections are credited to this website which is described as a "self-education tool about information technology, especially about the Internet and computers. It contains over 4,500 individual encyclopedic definition/topics, a number of "Fast Reference" pages and learning tools."

Consider the following with regard to components, peripherals and speed:

  1. Processor and Speed: Essentially the brain of a computer, a processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. Instructions are the orders given to a processor by a computer program. The term processor has generally replaced the term central processing unit (CPU).

  2. Hard Drive Memory: In a personal computer, a hard disk drive (HDD) is the mechanism that controls the positioning, reading, and writing of the hard disk, which furnishes the largest amount of data storage for the PC. Although the hard disk drive (often shortened to "hard drive") and the hard disk are not the same thing, they are packaged as a unit and so either term is sometimes used to refer to the whole unit. Are you storing information primarily on this machine or your server? How many programs do you have and what hardware and RAM requirements do they demand?

  3. RAM memory: RAM (random access memory) is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor. RAM is much faster to read from and write to than the other kinds of storage in a computer, the hard disk, floppy disk, and CD-ROM. However, the data in RAM stays there only as long as your computer is running. When you turn the computer off, RAM loses its data. When you turn your computer on again, your operating system and other files are once again loaded into RAM, usually from your hard disk.

    RAM can be compared to a person's short-term memory and the hard disk to the long-term memory. The short-term memory focuses on work at hand, but can only keep so many facts in view at one time. If short-term memory fills up, your brain sometimes is able to refresh it from facts stored in long-term memory. A computer also works this way. If RAM fills up, the processor needs to continually go to the hard disk to overlay old data in RAM with new, slowing down the computer's operation. Unlike the hard disk which can become completely full of data so that it won't accept any more, RAM never runs out of memory. It keeps operating, but much more slowly than you may want it to.

  4. Monitor: Does your job require you to have a screen that has a high resolution or will a lower resolution suffice? For word processing or spreadsheets and lower screen quality is adequate, while the highest resolution is preferred for graphics work.

  5. Video Card: An integrated circuit card in a computer or, in some cases, a monitor that provides digital-to-analog conversion, video RAM, and a video controller so that data can be sent to a computer's display.

  6. Speakers and Sound: If audio editing, music and production is your computer's primary purpose, choose speakers that assist you in doing your job best.

  7. Printers and Scanners: Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing. An inkjet printer sprays ink from an ink cartridge at very close range to the paper as it rolls by. A laser printer uses a laser beam reflected from a mirror to attract ink (called toner) to selected paper areas as a sheet rolls over a drum.

    Printer resolution (the sharpness of text and images on paper) is usually measured in dots per inch (dpi). Most inexpensive printers provide sufficient resolution for most purposes at 600 dpi.

    Having more than the minimum amount of memory is helpful and faster when printing out pages with large images or tables with lines around them (which the printer treats as a large image).

  8. CD Writers: A CD-ROM (Compact Disc, read-only-memory) drive is the mechanism that reads and writes computer data to CD-ROMs. A CD-ROM is an adaptation of the CD that is designed to store computer data in the form of text and graphics, as well as hi-fi stereo sound. Because of the larger programs most computers use, most pc's now come with a CD-ROM drive as opposed to a floppy disk. Most computers now have the option of coming with a CD-R drive, a recordable version of the CD drive. Though you need a CD-R to record to. You can store up to 600MB on one of these CD's.

  9. Modem: "Modem" is an acronym for MOdulate-DEModulate. A modem is a device or program that enables a computer to transmit data over telephone lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts data from analog to digital and vice versa (modulating and demodulating), thus enabling two computers to communicate with each other over a phone line.

  10. Network Card: A network interface card (NIC) is a computer circuit board or card that is installed in a computer so that it can be connected to a network. Personal computers and workstations on a local area network (LAN) typically contain a network interface card specifically designed for the LAN transmission technology. Network interface cards provide a dedicated, full-time connection to a network. Most home and portable computers connect to the Internet through as-needed dial-up connection. The modem provides the connection interface to the Internet service provider. Will this computer be part of a network, or will it stand alone?

  11. Operating System: An operating system (sometimes abbreviated as "OS") is the program that manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services.

    Check your software requirements to see what they recommend as optimum to run the programs you need to run your business. Is that the one you want/need? Will it be compatible with the other operating systems in your office?

  12. Application Programs: Examples of application programs include word processors; database programs; Web browsers; development tools; drawing, paint, and image editing programs; and communication programs. Application programs use the services of the computer's operating system and other supporting programs. Making sure your application programs are compatible with the operating system of the operating system and existing or planned hardware must be considered at the same time.

Hardware and Software Considerations for Servers

Much like the brand name PC advertised on TV or in the mail, if a server has a price that seems too good to be true, it probably is. Unfortunately advertised prices do not include necessary hardware and software configurations required for most servers.

Below is a list of some basic things to consider when purchasing a server:

  • What processor and speed should you have?
  • How many processors should you have?How many network cards do you need?
  • What server Operating System do you need?
  • What level of redundancy do you need, RAID1, RAID5?
  • Should your hard drives be SCSI, IDE, SATA?
  • Do you need redundant power supplies?
  • Do you need an uninterruptible power supply (UPS)?
  • How much storage space do you need?
  • What backup hardware and software should you use?
  • How many users are on your network?
  • What is the role of this server, file and print, database, application?
  • How many employees do you need licenses for (assuming each employee has a workstation)?
  • What software packages will you need in addition as complements to your operating system?
  1. RAM: Having more RAM for a server is of the essence. Skimping here will cause frustration as all the people in your office use the server for retrieving or storing information simultaneously.

  2. RAID: RAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks. By placing data on multiple disks, operations can overlap in a balanced way, improving performance. How critical is the data that you are storing on your server? Do you want to ensure that it will not be lost?

  3. Backup Hardware: Backup is the activity of copying files or databases so that they will be preserved in case of equipment failure or other catastrophe. Backup is usually a routine part of the operation of large businesses with mainframes as well as the administrators of smaller business computers. For personal computer users, backup is also necessary but often neglected. The retrieval of files you backed up is called restoring them. How are you backing up your data in the event of a hardware failure?

Please note: Most servers do not come with an operating system or other necessary software components.

Conclusion:

"Business owners often suffer from 'sticker shock' when a PC or server is configured for them," says Mike Carpenter, Director of IT Services at Corporate Computer Services. "Unfortunately, they are used to seeing advertised prices for bare bones systems that will not accomplish their goals. The systems advertised are not realistic examples of what is necessary for business today, and part of our job is to help clients understand the investment they are making for the long term when they purchase the equipment they need."

In the end, it is better to do your research than end up with a computer or server that does not satisfy your business requirements.

What Are the Most Important Considerations for Buying a Server?


What Are the Most Important Considerations for Buying a Server?

 

What Are the Most Important Considerations for Buying a Server?

Buying a server consists of knowing a variety of information about what the server will be used for and the types of programs it will need to have as well as hardware configurations. Because of this, there are many components that go into buying a server. This guide will go through what a server is and the various considerations for buying a server that users must know if they want to pick the perfect server for their needs.


What is a Server?

A server is a computer that provides data to other computers. There are servers that are central locations for storing information shared by many other computers, email servers, and even print servers that are designed to ensure all of a company's print jobs are printed on the right paper at the right printer. While servers can run on different types of computers, it is important that the hardware is sufficient to support the demands that will be placed on the server.


Considerations for Buying a Server

There are many things to consider when buying a server and many of them are related to the hardware the server is built with. A server is just a computer that works for other computers, so all of the parts of the computer are important just as they are for other computers. Listed below are some of the most important things to consider that should help any buyer pick the hardware for a server computer.

The Computer Case

Questions to consider when picking out a case: Does it hold all of the hardware? Do the buttons and the lights work? Are there USB ports on the front or just in the back? More so than any other component, the case is self-explanatory in that buyers only have to look at it to know how it works. Understanding what the case does, how it works, and why it's designed the way it is will help buyers make good choices. But the right casehas the potential to make a mediocre system okay and a good system great.

The Size Does Matter

Unlike with motherboards and processors, a case's size doesn't need to be explained. Bigger cases can hold more optical drives and more hard drives, have room for bigger video cards, and are easier to work with. The terms full tower, midtower, and minitower are sometimes used to suggest cases' decreasing size. Buyers will need to think about the form factor. This term refers to the general design of the case's interior, and to the type of motherboard the case supports.

Keep It from Overheating

The biggest way that a case can affect a system's performance is in how well it can cool the interior area. Buyers will want to pay special attention to what sort of fans the case has out of the box and how many can be added to it later. Most all computers have an exhaust fan on the rear panel for drawing out heated air, and some have intake fans on the front panel for pulling air into the case. The intake fan is usually placed near the hard drives, so that they can be cooled before the other components. The more powerful the system, the more additional fans a buyer is likely to see; high-performance servers can also include extra exhaust fans in the case's ceiling, or intake fans in the side panel. One thing a buyer should keep in mind when deciding which fan or fans to use is that the more fans a case has, and the smaller they are, the more noise the computer makes. Large fans can move more air while spinning more slowly, and will in turn keep the server from roaring like a jet engine.

The Hard Drive

This is the most critical component of the computer system, after the CPU and the memory. The hard drive is the hub where the operating system, programs, and data are permanently stored and accessed.

If the server will be used for large data transfers and high-use programs, a large and fast internal Parallel or Serial ATA hard drive can improve the overall computing experience. If more storage is needed or a buyer wants to back up the internal drives, they can add an external hard drive. Some versions available are: USB 2.0, FireWire 400 or 800, or external SATA. If a buyer wants a centralized storage, he or she should consider buying a network-attached storage device. NAS devices are constantly improving, and can be a convenient way to add storage that all of the computers on the same home network can share.

Data Storage and Handling

With the introduction of perpendicular magnetic recording, the terabyte became available to consumers as a larger capacity drive for personal computers. Given how quickly new technology is being invented, it's safe to assume that the drive that's bought today will give a buyer more storage capacity for less money than the one that could have been bought a year ago. When considering storage for server machines, keep in mind how much space will be needed and the potential for increased requirements in the future.

The Number of Hard Drives

If a buyer wants high capacity inside their server, they need only to remember that it doesn't have to be contained all in a single package. Most computers have room for at least two internal hard drives, and a typical large tower can hold even more. A buyer can usually save money by purchasing two 500GB drives instead of a single 1TB. Also, a buyer will want to insure they have available interface ports. If not, they may have to purchase an add-in card.

Memory

Memory comes in several shapes and sizes. It is important to get the correct memory for the specific motherboard the buyer possesses. There are four main types of memory:

SIMM: Single In-Line Memory Module

This is an older technology that dates back to the earlier days of the Pentium. Few people use it today; however, the term is still used by many when referring to memory.

DIMM: Dual In-Line Memory Modules

Also known as SDRAM, it is still supported by many motherboards. It has the advantage of being inexpensive and compatible with both Intel and AMD processors if the computer has the correct motherboard.

DDR DIMM: Double Data Rate SDRAM

It is faster than DIMM; however, the motherboard must have special sockets to support it. This is mainly used on AMD Athlon-based motherboards, although it is supported on some Pentium motherboards.

RIMM Rambus or RDRAM

This was the memory that Intel designed the Pentium 4 around. It is the fastest and in turn the most expensive memory available.

Network Card

When purchasing a network card, look at the available connections that the card allows. This is not as important as it has been in the past since many networks are using RJ45. If the network utilizes a different interface, such as Coax, buyers will want to verify that the card they are planning on purchasing has this connection.

Card Interface

The interface that the card connects to is an important consideration. Below is a listing of the three available interfaces.
 

Interface

Description

PCI

The PCI interface is suggested solution for desktop computers as it is a much faster solution compared to the ISA interface. On the other hand this is a little more expensive solution compared to ISA interface.

ISA

The ISA is a solution found with 10 Base network cards. The ISA cards are a less expensive option; however, compared to PCI, they are somewhat slower.

PCMCIA

The PCMCIA is a solution that is used with laptop computers and, in fact, are the only option for laptop computers.


When looking to buy a PCMCIA card, it is important to look at the connection and the slots used as well.

Connection is of course the most important consideration. When looking at PCMCIA cards, a buyer needs to look at the connection, and if any extra cables are needed to connect the network card to the network. These cables can become lost and sometimes damaged. The other options to additional cables are cards that contain the actual connection on the card.

It is important to verify the card being used as it utilizes the type II connection. If the card uses a type III connection, one needs to verify that the other cards are able to be inserted.

Operating System

Most desktop or laptop computers come pre-loaded with Microsoft Windows. Macintosh computers come pre-loaded with Mac OS X. Many corporate servers use the Linux or UNIX operating systems. The operating system (OS) is the first thing that is loaded onto the computer.

Operating System Functions

On the simplest level, an operating system has two functions:

1.     It manages the hardware and software resources of the system. In a desktop computer, these resources include such things as the processor, memory, disk space, and more.

2.     It provides a stable, consistent way for applications to deal with the hardware without having to know all the details of the hardware.

Even if a particular computer is unique, an operating system can ensure that applications continue to run when hardware upgrades and updates occur. This is due to the fact that the operating system, not the application, is charged with managing the hardware and the distribution of its information. Today's systems can accommodate thousands of different printers, disk drives, and special peripherals in any possible combination.

Processor

The processor is the brains of a computer, so choosing the right one is key. Below are some terms to become familiar with in order to choose wisely:

64-bit Support

Almost every computer on the market today is a 64-bit model, which means it can process 64 bits (or 8 bytes) of information at one time. Due to so many of today's apps, from Windows to Photoshop, supporting 64-bit technology, buyers are better off avoiding 32-bit processors should they happen to come across them.

Cache

Cache can be a bit confusing, especially in part because there are three different variations, and the names are very similar: L1, L2, and L3. Understanding that the L stands for level, will help to make cache easier to understand. L1 is the primary cache. It is the fastest section of the memory and the one most directly responsible for a processor's performance primarily because this is where instructions are stored while waiting to be processed. L2 works in almost the exact same way; however, instead of sending instructions to the microprocessor itself, it sends them to the L1 cache, therefore using slower memory. The L3 cache sends the information to the L2 cache, and is even slower still.

Manufacturing Technology

This refers to the depth of the die from which the processor has been constructed. Over time, they have become smaller and more energy-efficient, and more powerful. The higher-priced computers on the market use 22 nm or 32 nm technology, and the older computers are typically at 45 nm or more. Buyers will rarely need to worry about this, the only exception being that they ensure that their processor works with the motherboard into which it is to be installed.


Buying a Server on eBay

Whether building your own server or purchasing one already built, eBay has vendors that can accommodate your needs. If you want to buy a server that is all set up and ready to go, you can search for machines on eBay using the following steps.

Searching for a Server on eBay

Should you be confident in the type of server you need, you can simply enter the name of it in the search bar available at the top of the page and search for it directly. For a more refined search, you can use the Advanced Search option. If you would prefer to browse the listings, you can begin with a search for Servers, and then you can narrow down the listings by category for a wider search.

You can start narrowing down the listings by navigating to the Computers, Tablets, & Networking, from there, select Drives, Storage & Media. Because there are so many variations of servers, utilizing a direct or advanced search would be advised.

Remember when buying anything on eBay to thoroughly investigate the item you are purchasing, such as a server to be sure it meets all of your criteria. If you are searching for a new server, be sure that the listing indicates that the machine you are considering is new. Also, because servers and their components can be pricey, be sure that the seller has a good feedback rating from other buyers and that the seller offers returns. This will help ensure that your purchase from a reliable seller and get the exact item you need.


Conclusion

For those who need to purchase or build a server computer, there are many things to consider, such as the processing speed of the machine needed and the amount of data it should be able to store. It's also important to consider the network card and how quickly the server will be able to move information across the network to meet the needs of the computer users who will be accessing the server. Whether you are going to build your own server, or buy one ready-made, eBay is an excellent choice because of its large variety of options available at any time.

 

10 mistakes that rookie IT consultants make


10 mistakes that rookie IT consultants make

1: Underestimating total project time

None of us is perfect. Unforeseen issues always arise. There are no "simple" projects. Consultants must take those issues into account when preparing project cost estimates.

The very first time I ever estimated a simple Windows Small Business Server rollout for a client with seven employees in two locations, I budgeted eight hours to "deploy the server." In developing my estimate, I included time to unbox and install the server, set up DNS, configure the VPN, join the second location to the VPN, register the domain name, configure MX records, create data shares, set permissions, and configure and test email accounts. Let's just say it took longer.

New consultants must be particularly careful to review project plans before settling on a final estimate that is forwarded to the client. Such estimates should be first run by veteran IT staff for feedback whenever possible.

2: Failing to properly document project scope

Why did my first server deploy take longer? In conversations with the client, when discussing the project, I was focused on the tasks associated with deploying the server. The client already had a peer-to-peer network in place. I saw my role as simply dropping the server on the network, joining workstations to the domain, configuring a VPN to give a remote but key employee data access, and introducing email.

But the client thought a "server deployment" included installing a couple network printers with network scanning functionality, upgrading Microsoft Office software on eight workstations, implementing site-wide antivirus, and other tasks. Such disconnects are the IT consultant's fault.

Clients are not technology experts. It is the consultant's responsibility to ensure that the client's business needs and objectives are understood and that the technology deployed matches them. Whenever estimating a project now, I provide clients with a project plan that lists specific bullet points. I don't just state "deploy server," "configure DNS," etc., as most clients don't know what that even means. Instead, before starting a project, I go through a project plan with the client that reviews tasks I will perform and the specific functionality those tasks will provide ("Users will store their files on the server's X drive," All users will send/receive email using Microsoft Outlook 2007 on their desktop workstations," "A new network printer will enable scanning documents and storing them over the network to a Z drive hosted on the new server," etc.).

3: Underestimating hardware costs

Just as it's easy to underestimate the time and labor required to properly complete a project, hardware costs frequently become a source of trouble. Here's one common scenario: An IT consultant specifies a particular gigabit switch or router when assembling a project budget using a temporary price because a vendor is offering promotional pricing (and the temporary price cut may NOT be evident when researching pricing). Or a server configuration may be priced using unique components. Ten days may pass before the client approves the purchase. Then, when the consultant proceeds to order the items, the server configuration and promotional pricing (or both!) are no longer available.

I see it all the time, even with one leading Texas-based computer vendor's promise of 30-day price locks. And I've yet to see one of these changes work in the consultant's favor. Whenever preparing project estimates, always note that hardware costs are subject to change. Be sure, too, to always include shipping costs in estimates. Clients should find no surprises when receiving a final invoice, but if the consultant neglects to include shipping costs in preliminary conversations, such fees will prove problematic.

4: Trying to master all technologies

An IT consultant cannot master all the technologies clients require. It's not going to happen. Some busy consultants will service three or four clients a day. There's no way that consultant is going to develop comprehensive expertise with all the myriad applications clients wield, such as Dentrix (dental), Timberline (accounting), QuickBooks (financial management), Intergy (physician practice), Act (database), Prolog (project management), Aloha (restaurant), and SEMCI Partner (insurance), as well as routing platforms (Cisco, SonicWALL, WatchGuard, etc.), Windows desktop and server operating systems, antivirus solutions, Exchange email, and others.

Determine which platforms you'll master. Then make sure you know who to call for assistance when troubleshooting problems with the remainder. Whether you're contacting the software manufacturer or another consultant to assist when servicing a platform with which you don't have expertise, you're performing a service for the client. Ultimately, clients typically don't care that you know every nuance of every program -- they just want a dependable partner they can call when they encounter technology issues.

5: Waiting to send invoices

Consultants, especially those starting a new business, are particularly eager to jump on new projects. It's seemingly best to always be billing. Given the choice between taking downtime to develop and mail invoices or go onsite to complete another service call, rookie consultants almost always favor knocking out additional service calls. But there's no cash flow when invoices aren't going out.

New consultants must schedule time, daily whenever possible, to write and distribute invoices. A CPA client gave me great advice. He recommended I always send invoices within a day of completing work. He told me studies reveal customer satisfaction is highest when invoices are received quickly.

It makes sense. Every day a consultant delays sending an invoice, clients forget a little more the pressing need that demanded the repair or service. When bills arrive three weeks or a month later, cash flow not only suffers, but customers are more likely to believe charges are excessive. This is because the business and operations interruptions and resulting trauma and downtime the consultant corrected have been forgotten.

6: Scheduling too many calls

When planning a typical workday, consultants should schedule one or two hours of time for every hour billed. Essentially, that means two to four service calls are the most that can be reasonably accommodated on any given day. A fair rule of thumb is that each member of an IT consultancy traveling onsite to resolve client issues should bill 20 to 25 hours per week. Any more than that, and you begin stretching resources too thin.

When scheduling client calls (I aim for four billable hours per day, which I have consistently met for years), you must include time for administrative and operational work. Numerous tasks require a consultant's attention, including managing payroll, accounting, QuickBooks data entry, internal IT, advertising, and marketing tasks.

7: Failing to market the business

Rookie consultants, whether working for a firm they own or as an employee within a consultancy, typically strive to maximize billable hours. The desire for billable hours sometimes comes at the expense of obtaining new clients and chasing larger projects. These consultants should do more than just report to work and service existing clients. They must take time to attend BNI, chamber, Rotary, and other networking meetings. They should distribute business cards at every opportunity.

Some consultants don't believe they have time for additional marketing responsibilities. That's a common mistake. The fact is, many business networking events end before 8:00 AM, so there's no excuse for new consultants not rise early and attend networking events before their regular work day begins. Recently, a longtime friend and insurance agent reminded me that, by scheduling 7:00 AM and 7:30 AM meetings every day, he's opened an additional 250 meetings a year on his calendar. That's impressive.

8: Overlooking travel costs

Many consultants, especially those new to consulting, don't realize the costs of travel time. Traffic is expensive. Very.

Consider the facts. If an IT consultant charges $115 an hour for onsite commercial work, and traveling to client sites consumes just six hours a week (it's likely much more), the opportunity cost of traffic and travel time to the consultant exceeds $30,000 annually.

Those costs must be captured. Typically, IT consultancies capture them in the form of onsite service fees, inflated first-half-hour rates, or other surcharges. Just this past week, a plumber completed work at my residence. The bill included a $35 "truck fee." That's nothing but fair. In addition to paying for fuel and wear-and-tear on a fleet vehicle, the plumbing shop needs to cover the time spent traveling to my home.

New IT consultants must remember to charge 30% to 40% more than their regular onsite rate for the first half-hour or simply add a flat-rate callout fee.

9: Charging too little

There's a natural temptation, especially among new technology consultants, to believe the rates they charge are expensive. But running a business costs money, lots of it, and technology solutions are complex. Consultants must remember that their expertise, and the delivery of onsite service especially, possess great value. Hourly onsite support rates vary from $85 to $125 or more per hour. But that doesn't mean a new consultant must charge just $85 per hour.

To the contrary. Local market conditions are usually the largest factor. The costs of delivering services is higher in Boston, where taxes, fees, parking, and other expenses are naturally higher than in Louisville, KY, where the costs of living are less. Thus, an IT consultant in Boston should expect to earn a higher hourly rate than a consultant in Louisville.

10: Working Saturdays

Technology consultants operate within a pressure-packed environment. This is likely the single greatest factor I underestimated when opening my own consulting shop almost four years ago.

Most clients don't call for help before critical systems fail. Instead, they wait. Then they try to fix it themselves. Next, they enlist the assistance of the local computer geek on staff. Often, the consultant is called only after these efforts -- and those of the business owners' friends, colleagues, and neighbors -- have failed to resolve the problem. As a result, IT consultants spend much of their time running from raging and complicated fires to blisteringly complex crises. It is fatiguing work. Many days, my technicians and I are physically and mentally exhausted by 2:00 PM.

Inevitably, clients request that consultants work weekends. I almost always say no. It's not that I so feverishly guard my personal time. Instead, as I mature and spend more time within the industry, I've come to understand the importance of approaching complicated issues with a fresh mind and properly fed body (of which I'm not making light; too often my staff and I must skip lunch because of new-client crises). How many times have you struggled with a complicated Windows issue at 1:00 AM, only to quickly solve it the next morning after getting some sleep and a decent breakfast?

The same principle is true within a consulting firm. Rookie consultants must take time to help their bodies, physically and mentally, recover from the rigors of their profession. That means minimizing weekend work, for better or for worse.
