Re: HMC Question

Mark,

 It's actually:

   Wall - > UPS - > PDU - > All your stuff.  Optionally you can also 
plug some of your stuff directly into the UPS if you'd like. 

   As for capacity you need to 'do the math' again and total up all the 
requirements of the servers, HMC, etc to find out if it's got enough 
juice. Plan B is to plug it all in and see if the magic smoke comes 
out.  I don't think that would make Cole happy though!!
