5 Tips to Save Energy on a Server

Servers use power, and the more dedicated servers you have, the more of an energy bill you will have to pay. Excessive energy consumption also negatively impacts the environment. Therefore, whether your motivation is for the first, the latter, or both, you will most likely want find ways to reduce power usage on your servers.

What follows are five tips that may help your server go a little greener:

1. Power management – Most Unix, Linux, and Windows servers come with built-in power management features. Some of them include CPU scaling, application power management, process power management, and reducing power consumption of certain hardware when it is not in use.

2. Virtualization – Using half a server to perform the tasks you need, just because that server needs to run a different operating system from your others, is an inefficient use of money and energy. In some cases, you can consolidate multiple server configurations on one machine using virtualization.

3. Cloud computing – Although this may just offset the energy consumption to another facility, it will reduce your own energy costs. Furthermore, if the cloud service provider has optimized their data centers for smarter energy consumption, it can reduce the overall impact.

4. Removing unnecessary services – Many times, a CPU will be awakened by a process that runs in the background, even if no one is accessing your dedicated server. Rather than wasting CPU cycles, remove the services that you do not need.

5. Smarter cooling – Heat can cause problems for your hardware and for the environment. Cooling systems can be very expensive, especially for large servers. If heat is a real issue, consider looking into more affordable, low-powered cooling solutions.
