Upcoming Series: IBM and HP Blade Power Planning
Posted by: Aaron Delp in HP Blades, IBM Blades
In the near future I will be starting my first series of posts here at The Blade Blog in addition to the standard news postings. The number one area I receive questions about for both IBM and HP Blades is power. Anything from the types of plugs, how to set up the PDUs, how many Amps/Watts we’re going to draw, etc.
So, I was wondering what areas you would like to see more information in regards to power. I plan on covering both the HP and IBM Power Tools (did you know they had power tools?), PDUs and plugs, Amp and Watt calculations, power supply domains and failover scenarios, and other topics as they come up. I would love your feed back on the subject!

Aaron - all of the above please!!! 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…
In summary - power calculations as it pertains to pay-per-circuit, not per kw/hr.
BTW - Nice Blog

Hey Don - Colo’s do tend to be quite a challenge when utilizing blades, especially when you tell them you will need multiple 208V feeds! Colo’s love you for that…
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!
