Colo's love you for that...<br/><br/>I'd be happy to try to provide that information. Also, are you looking for HP, IBM, or both? I plan to go into the power management features built into the Management Modules (IBM) and the Onboard Administrator (HP) at some point. If you have a preference I will do that vendor first.<br/><br/>Thanks for the comment!

I’d be happy to try to provide that information. Also, are you looking for HP, IBM, or both? I plan to go into the power management features built into the Management Modules (IBM) and the Onboard Administrator (HP) at some point. If you have a preference I will do that vendor first.

Thanks for the comment!

One particular challenge I face is Colo facility power. Most Colo's charge for power on a per-circuit charge. Most power calculators are focused on Kw/hr. I am trying to look at better utilizing each circuit = 1k/per circuit - you get more systems on the circuit, but it gets challenging with knowing system utilization - and where you can "cap" a blade chassis safely, and thinking about failover, etc...<br/><br/>In summary - power calculations as it pertains to pay-per-circuit, not per kw/hr.<br/><br/>BTW - Nice Blog<br/><br/>-don Aaron - all of the above please!!!

In summary - power calculations as it pertains to pay-per-circuit, not per kw/hr.

BTW - Nice Blog
