Guide to Buying A Server

Buying a server is a big decision for anyone, whether you are a large firm, a little start-up or one person. Though servers cost more than your average desktop or even high end laptop, servers handle many more processes than either the desktop or laptop and are very unlikely to crash or bog down with heavy usage.

Servers Have Multiple Processors
A server has multiple processors, 2 or more CPUs, to handle the many requests for data its gets all day long. When one of the users makes a huge data request you don�t want all the other server data requests from the other server users to be delayed. Servers with more than 1 CPU can do more things at once and are able to respond faster to your requests. If you are looking to start off small I recommend getting a Multi-CPU capable motherboard but start with one CPU, thus saving yourself hundreds of dollars.

Servers Have SCSI Hard Drives
SCSI hard drives are the only hard drives suitable for heavy duty servers. SCSI hard drives spin faster then IDE hard drives and therefore are able to read more data more quickly.

Servers Use RAID
RAID (Redundant Array of Inexpensive Disks), keeps multiple hard drives with the same data on each, so if one of the hard drives goes off the deep end, you have at least one more ready and waiting to take over for it instantly. For example, a user saves a file to the network drive; the file is not just saved to the one drive but all the drives on the RAID system.

Servers Use Tape Backup Drives
The one �flaw� of the RAID system is that if a user deletes a file that they didn�t want to delete, it is gone from all drives. That is why you should always use a tape backup drive to keep your files safe. One thing to make sure is that you use bigger tapes than that of your hard drive or you will find yourself changing your tapes in the middle of the night to keep the backup going.

Servers Use Redundant Components
Servers use multiple components of the same type, like 2 network cards or 2 power supplies, so that if one piece of equipment dies the other one takes over. Servers are now even capable of hot swapping components, replacing components while the server is still on. Hot swapping is a very useful for servers that can�t afford to have ANY down time, web servers for example.

Servers have many uses and require a large amount of hard ware, but they are second to none for managing all sorts of data, whether you are using it to host your companies files or run a web server to host dozens of web site, servers can handle it all. All you need to do is purchase computer parts that can meet you needs.
