Crash course: Data centre power

Keywords:power consumption  data centre power usage 

Five years ago, the average power requirement per rack was 1 to 3 kilowatts. With requirements for processor cycles, memory and storage continuing to grow, along with the density of the equipment packed into each rack, it's now common for a typical rack to require 5 to 7 kilowatts, with high-density blade server implementations hogging 24 to 30 kilowatts per rack. Couple this dramatic increase in power consumption with the rising price of electricity and it's clear why this issue is becoming increasingly critical.

If your data centre redesign is still a year or more away, consider spending capital now on power usage-monitoring equipment. Also, the idea is to attain the lowest TCO since power and cooling costs are escalating. Instead of installing a fully loaded PDU-UPS combo,deploy two or more sparsely configured combos toward future expansion. Another option to consider is the potential energy savings afforded by switching from AC- to DC-powered servers and storage in the data centre.
