Power and cooling: Cisco vs. Enterasys

In data center design, power and cooling constraints are one of the top issues. Below are two charts that compare the power consumption and cooling requirements for some popular Cisco switches compared to some popular Enterasys switches:

Enterasys	Max Power Draw	Cisco	Max Power Draw	Percentage More
N-Series	1500W	6509e	3000W	100% more than Enterasys
N-Series w/PoE	5100W	6509e	8700W	70% more than Enterasys
N-Series	1500W	4506e	4200W	180% more than Enterasys
G-Series	1050W	3560e	1150W	9% more than Enterasys, but only half the ports
C-Series	583W	3560e	1150W	97% more than Enterasys

Enterasys	Max Thermal Load	Cisco	Max Thermal Load	Percentage More
N-Series	5463 BTU/Hr	6509e	16800 BTU/Hr	207% more than Enterasys
N-Series w/PoE	17755 BTU/Hr	6509e	34800 BTU/Hr	99% more than Enterasys
N-System	5463 BTU/Hr	4506e	14340 BTU/Hr	162% more than Enterasys
G-Series	3585 BTU/Hr	3560e	3927 BTU/Hr	9% more than Enterasys, but only half the ports
C-Series	1991 BTU/Hr	3560e	3927 BTU/Hr	97% more than Enterasys

As you can see above, Enterasys requires half the power and half the cooling of equivalent Cisco devices.

What do YOU think of vendor power consumption and cooling requirement comparisons?
