To defend the IBM blades they boast lower power than 1Us and many other
blades. It's the density that pushes the cabinet above data center
norms. You can fit 84 blades in a cabinet which is comprised of 168
CPUs, (336 cores,) 168 SCSI hard disks, 24 Ethernet, Infiniband and/or
SAN switches, and 12 management modules with KVM over IP. 

That's quite a bit of gear for 40KW and considering that it's probably
peak consumption, it could commonly run on less. Also that figure may
take into consideration the redundant power supplies. The system may
only need 20KW to function and have the other 20KW as redundant power.
