You can skip Vista

windows-7-logoWe continue to have clients ask whether they can buy new computers with Windows XP instead of Vista. Deserved or not, Vista has a terrible reputation, and Microsoft is responding by rushing the next round of Windows to market as soon as possible: Windows 7.

There’s not a firm release date yet, but the product is already in beta, available for download to anyone who wants it. Speculation suggests it will be officially on the market this October.

Early reports say it runs better and faster than Vista so it looks like this one might be a winner.

The difference between a server and a desktop computer

Server Software

Regular computers usually run some flavor of Windows, like XP or Vista. Macs of course run Mac software (OS X), and there are also open source desktop alternatives such as Linux.

Servers generally run more powerful operating systems that can handle networking, email, internet/intranet hosting, file sharing, databases, and more. Windows Server and Windows Small Business Server are quite popular in small and mid-size businesses. Mac offers OS X Server if you want to run your entire network on Macs.

Linux servers are also a popular choice. Because this is an open-source option, there are many different choices, referred to as distributions. Popular examples include Red Hat, Ubuntu, and SUSE. Some distros are better suited to handle server requirements while others are intended as a desktop operating system.

With Windows and Mac, there’s one more software component you’ll need: client access licenses (CALs) that allow computers on the network to connect to the server. In most cases you need one for each computer; they are usually sold in packs of 5, 10, and 25.

Server Hardware

The second major difference between computers and servers: better hardware. You’ll generally see better quality parts and more redundancy (duplication of hardware). The reason? If a desktop goes down, it impacts a single person. If a server goes down, it can easily impact dozens, even hundreds of people at once.

Better quality parts used to be something you could take for granted. However, if you purchase a no-name brand or even a really low-end name-brand, the quality difference will not be great. You often get what you pay for, and it’s difficult to do a true apples-to-apples comparison.

Redundancy is easier to check up on. RAID is a must even on a budget server–it stands for redundant array of inexpensive disks and keeps your server from crashing if a hard drive dies. More expensive servers add a wide variety of features from hot-swap removable drives to dual power sources. Multiple processors and plenty of memory (RAM) keep things running smoothly even for resource-hungry software applications.

You can select a tower case, just like a normal desktop computer, or a rack-mountable case. This is largely a question of convenience. If you have several servers, it is most efficient to mount them in a space-saving rack. If you have just one or two, it may not make much difference.

Vive la difference!

Now that you know the difference, you can shop smart, balancing price and reliability to get the server that best meets your needs.
