power savings

One-third virtualized, already saving thousands on power

Link: Power savings through virtualization « Documenting a virtualization project.

So far, 33% into our project, we have been able to reduce our power requirement in datacenter 1 by 3.7 KiloWatts (18.7 down to 15.0) and in datacenter 2 by approximately 1.5 KiloWatts. …


Because we are virtualizing everything to one production datacenter we will eventually be able to shut down datacenter 2 for production (which will mean less stringent requirements on cooling, UPS etc.). It will be interesting to see what the final outcome is for the project.

So how’s my math .. 5 kW savings per hour x 24 hours/day x 365 days/year x $0.10 per kWh = $4555 savings in a year. I think they just paid for an ESX Server with that. If they lived in California, they’d be getting addititonal credits from the electric company. And that’s before they pull down datacenter #2.
