Determine if a 2U server is right for you 2U rack servers can pack quite a punch for a unit of its size. That being said, the power a 2U rack gives you is still considered mid-range, when compared to larger rackmount units and tower servers. As such, make sure a 2U rack server will give you enough power. Another option is to buy several two unit rackmount servers, and chain them together to add power to your system.

I recommend:  Dell offers a comparison of their own server models that can be applied to virtually any rackmount server. Look at this chart to determine if a 2U server is adequate for your needs.

Check out traditional computer manufacturers' offerings The first place to look for your 2U rack servers should be the traditional well-known computer manufacturers. Most of these companies, such as Dell, HP, and MPC, produce a full like of 2U racks, pre-built at a reasonable price. In addition, when you purchase from these companies, you will receive their full warranty and support services, which will be invaluable in maintaining your servers.

I recommend:  HP and MPC are among the companies that offer a full line of two unit rack servers. Both companies have great reputation, and their products are worth a look.

Look into custom server options If the pre-built servers you looked at just don't seem to be the right fit, customization is another option. Several companies will build your 2U server from the ground up. While in some cases these units may cost a little more, the end result is a 2U rack server that is tailored specifically to the needs of your network.

I recommend:  Aberdeen offers several 2U rack models that are fully customizable. TigerDirect is one of the best third-party computer retailers around, and boasts a great selection of custom 2u rack mounted PC servers.
