Servers store data and programs that will be shared and used by many different people. A typical small office with a number of computers will have one or two servers connected by a network. Servers typically run your email and CRM software and control access to files and printers.
Think of a server as a shared resource and a repository for your business information. Given its central role and the fact that multiple users can be accessing resource on it simultaneously, its specification needs to be much greater than the typical computer.
Your server must be capable of rapid repair, since a breakdown will halt most of your IT functions. Servers are often built so that key components such as disks and power supplies can be quickly changed. More expensive servers will have redundant components, so that if one fails another will take over automatically.
Servers are normally kept in a secure location, often alongside your networking equipment. It is important to prevent casual, physical access to your server because of the damage that could be done to your business information. Servers should be protected from power failures by Uninterruptible Power Supplies (UPS), which provide battery power during a power failure and give the server enough time to safely shut down without damage to your data.
A server maintenance contract is a wise investment, especially if you have limited in-house IT expertise.
