Choose the operating system and hardware configuration of the network rackmount server Rack servers must be configured with the necessary processing power, memory and hard drive space. A lower-end server can handle simple tasks like file sharing and network management. Application, web and database servers require more processing power, memory, and hard drive space. If you want the operating system pre-installed, you'll need to choose which one you want.

I recommend:  If you'll be using the server to run an application, ask the application developer to recommend an operating system and to provide specs including recommended processor, memory and disk space. For a simple file server, Windows Server is probably easier for non-technical staff to manage than Unix based systems. Most rack mount server manufacturers, such as Dell and HP, provide guidance in choosing the best hardware configuration for your needs.

Determine what type of support and management you need If you don't have an IT team or service provider, make sure you get a server that is pre-configured and includes comprehensive support and remote management.

I recommend:  Budget for extra support services along with the cost of the server. If your network is growing, now might be the time to consider hiring a local service provider, or getting remote support from an enterprise. IBM offers various hardware, software, and managed support options. ServPath and other companies provide on-site and remote management and support.

Buy the server Once you've decided on a configuration, compare prices from various rack server providers and purchase the rack server.

I recommend:  If you need support, buy from a company like IBM or HP that has longevity and a great reputation. If your IT guy can fix anything, consider purchasing a used server or buying cheap from a lesser-known company.

Purchase a server rack and accessories You can buy a rack for servers from the server manufacturer or other sources. Racks generally are sized from 14U to 48U. Some racks can be mounted to a wall or fit under a desk.

I recommend:  If you plan to add other servers, rackmount network gear, or other equipment, buy a server rack that can hold it all. If your rack is going to be located in a dusty environment, invest in a server cabinet instead of just an open rack. Add extras to keep things neat, like monitors or keyboard monitor combination drawers. Make sure doors, shelves, and sides are well ventilated. Make sure the cabinet has a cooling fan.
