Centralized PC power managers not created equal

By Logan G. Harbaugh, InfoWorld |  Green IT, environment

Companies are anxious to reduce power usage these days, both to save cash on energy bills and to reduce their environmental impact. One area that's ripe for power savings is the desktop. At companies across the globe, end-users leave their computers and monitors on day and night for any number of reasons, be it for late-night backups and patching or ensuring they can get cracking the moment they sit down at their desks each morning.

These conveniences come at an overlooked price: Keeping a PC running 24/7 can cost as much as $375 per year, depending on the type of computer and monitor, as well as energy rates in your region. Shutting down a PC for 16 hours or so per day can cut those costs by 66 percent. That translates to potential savings of more than $120,000 if you have 500 machines.

Rather than relying on end-users to power down their machines and monitors each night, then reboot them in the morning, organizations are increasingly turning to power management offerings, products capable of powering machines on and off at predetermined times to ensure that they're awake when it's time for work, backups, or patches. Otherwise, they'll be asleep so as not to waste energy and money.

I had an opportunity to test out three power management software systems aimed at the enterprise desktop market, from vendors Autonomic Software, BigFix, and Symantec. Notably, all three software products are part of suites intended to provide a great many more PC management functions beyond control over power usage, such as remote desktop support, configuration and patch management, vulnerability assessment, and endpoint protection.
