1u chassis from SMSMAN's blog

Many people don’t even consider the benefits of having a decent server chassis and altogether disregard the expansion limitations they might reach down the long road. In fact there are two primary server problems that can be routed back to a server’s chassis – overheating and server expansion limitations. Consider these three major points when looking into a server chassis.

Ventilation

It takes a lot of power in order for servers to operate, so much power in fact that in response they generate much heat. That heat must be diffused in order for servers to continue working properly.

It is recommended that full tower models own front and back case fans. In addition, the sides of the case should have fans and vents too. Power supplies should have their very own cooling fans while 1U server systems have at least four 56mm cooling fans (system’s hard disks, processor(s), and expansion cards. With 2U servers add a fifth 56mm fan for cooling internal components.

When adhering to certain server 1u chassis specifications, pay attention to models that include hardware-based support. That way you are to be alerted when your fans have low RPM and show other failures. Ensuring your cooling fans work properly will help keep your servers at optimal conditions.
