Power Manage Your Servers

Power manage your servers

Once you have determined which servers are performing various levels of work, you have the opportunity to conserve significant amounts of electricity. First and foremost, of course, you can take servers down completely, directly reducing the electrical draw of the data center. Or you can at least slow the addition of new servers by repurposing the servers you have already provisioned.

CPU throttling is an increasingly popular-and effective-measure to reduce power consumption in servers. Lower CPU speeds not only directly reduce the power draw, they also affect the power draw of other components such as disk drives. Leading server operating systems and vendor-based hardware tools incorporate some rudimentary CPU-throttling features. However, newer, dedicated utilities can do an even better job of managing processor speed.

For instance, they can cap the CPU speed for non-useful work (calculated based on the application work it is processing). While some might worry about potential degradation in performance, the impact is uneventful because the processing is not time-intensive, takes place in off-peak hours or involves non-critical applications.
