I somewhat agree with Stevie but in the future when the ability to recoup the cost of un used power in a datacenter is the norm then DPM will be a must have. also i think sometimes these things are about perception. If my bosses think they are saving money then they will buy the feature. Having said that it works fine albeit the issue Frank has highlighted. if only DPM was more DRS friendly, here’s hoping!

Keep watching VMware, they are aware that DPM is not a panacea and are working with various vendors to make DPM more robust. Eventually you will be able to power down entire rows and turn off the PDU’s and AC units feeding those rows for significant power savings.

Re: DPM is a gimmick from Steve.

I guess to each his own. But I did feel that the comment was a little one-sided. Just because large data centers are built the way you describe doesn’t mean that the rest of the world cannot benefit from DPM.

DPM is a gimmick. In the data center you have already paid for and are running power and cooling and facilities: turning of a few servers saves some watts and cash, but it’s miniscule.

The better option, which I was going to demo @ VMworld until I was sent a Dear John letter, is to use your investment as much as possible.

If you want to be green in the data center, you probably need a new type of data center that has PUE of less than 1.5. DPM will have zilch effect on your PUE.
