What's important in a server




Looking Closure at Servers:
 Server computer are the lifeblood of any network. Servers provide the shared resources that network users crave, such as file storage, databases, email, Web services, and so on. Choosing the equipment you use for your network's servers is one of the key decisions you'll male when you set up a network.In the following sections.I describe some of the various ways you can equip your network's servers.

What's Important in a Server
Here are some general things to keep in mind when picking a server computer for your network....

Scalability : The ability to increase the size and capacity of the server computer without unreasonable hassle. Purchasing a server computer that jut meets your current needs is a major mistake because (rest assured) your needs double within a year. If at all possible, equip your servers with far more disk space , RAM, and processor power than you currently need.

Reliability: The old adage 'you get what you pay for " applies especially well to server computers. Why spend $5000  on a server computer when you can buy one with seemingly similar specifications at a discount electronics store for more $1000 ? The main reason: reliability When a client computers fails , only the person who uses that computer is affected. When a server fails however , everyone on the network is affected. The less-expensive computer is probably made of interior component that are more likely to fail , and does not have redundant components built in . (For example, many server computers have two power supplies, two CPUs, two or more network interfaces, and other redundant components.)

Availability: This concept is closely related to reliability. When a sever computer fails, how long does it take to correct the problem and get the server up and running again? Server computers are designed so their components can be easily diagnosed and replaced, which minimize the downtime that results when a components fails. In some servers , component are hot swappable (certain components can be replaced without shutting down the servers.). Some servers are fault-tolerant so that they can continue to opearte even if a major component
fails.

Service and support : Service and support are often overlooked factors when picking computers. If a component in a server computer fails, do you have someone on site qualified to repair the broken computer.
Don't settle for a maintenance contract that requires you to take the computer in to a repair shop or worse, mail it to a repair facility. You can't afford to be without your server that long. Get a maintenance contract that provides for on-site service and repair of your server, 24 hours a day, 7 days a week.
