There are a few different profiles for computer servers: rack, blade, and tower servers. Rack servers have grown in popularity in small and large business environments. They range in size from 1U to 7U. A "U" is equal to 1.75 inches and refers to how many units the server takes up in a rack.

A rack environment can save space and power. While they are most often seen in data centers, a rack is an excellent solution for a small business that has, or plans to add, rack mount equipment such as network switches and additional servers. Choosing a computer rack server for small business requires a little more planning than the purchase of a tower server. Special considerations include:

1. Selecting a computer server rack that is compatible with your server and can grow with your network

2. Choosing a rack optimized server to run your applications

3. Adding accessories for optimal organization, cooling and power management

The best contacts and resources to help you get it done

Select a computer rack server for small businesses

The first step is to choose a server. Uses for Rack servers include web servers, application or file servers. Get the server specifications for your operating system and applications before ordering the server.

I recommend: Dell and IBM offer a selection of rack optimized servers. Hewlett-Packard (HP) features a server buying guide that allows you to choose the right server based on the number of users, applications and operating systems.

Browse selections from computer server rack manufacturers

Racks are available in sizes up to 44U. A rack can be purchased from the server manufacturer, but third party server rack manufacturers often have better deals and more selection. Racks vary slightly in size and assembly. Check the width and depth of your server to ensure you get the right sized rack.

I recommend: Information Support Concepts offers small computer racks and cabinets, starting at 3U. Racks Unlimited features a variety of sizes and configurations, including wall mount and free-standing racks. Save space by putting your existing tower servers in a rack. If you have a computer server rack and towers, use tower converters. Dell offers converters to mount their tower servers. HP converters can be purchased from PC Connection.

Get the right accessories from computer server rack suppliers

Add accessories and solutions to your rack to improve management and efficiency. Cooling and ventilation are major considerations in a data center rack space, since the equipment generates heat that can damage cables and other equipment. Rack mount monitors, keyboards and other accessories keep things neat and accessible.

I recommend: Get racks that incorporate ventilation and cooling solutions. American Power Conversion (APC) manufactures air conditioners that can be installed in its racks. 42u sells a variety of cooling and ventilation solutions. Rackmount Equipment offers rack mount monitors, keyboards and other accessories.
