Now we have over 110 VMware guests running and growing, ranging from Windows server to Linux to FreeBSD. We currently have 21 Dell blades with RHEL 5 and WMVware ESX suite installed.

Doing it over, I'd rather concentrate my systems in a multinode 1u chassis with more even rear-discharge air than a blade system with forced vertical exhaust.

If are space on one of the largest data center providers they will charge you the same amount of money for power regardless if your servers can run on lower power when not fully used. On an outsource datacenter you pay full price for the maximum capacity of a 120/20 and the corresponding cooling that is associated with that power. That is: Amps * Volts = Watts Watts * hours = watthours watthours * 3.41214148 = Btu Blades Cost More
