EMC Symmetrix V-MAX Green claims

EMC claims Symmetrix V-MAX consumes 20% less power per TB compared to DMX-4

Here is my calculation which will prove it wrong.

V-MAX uses 24.2% more power per TB compared to DMX-4. EMC’s claims on using 20% less power per TB is false. These claims are absolutely outrageous about being green. May be DMX-4 is greener than V-MAX.

DMX-4 supports 1 System Bay and 8 Storage Bay. Maximum Scalability 2400 Drives(can be flash, FC or SATA)
As per my earlier calculation of power consumption

1 x System Bay * 6.4kVA = 6.4kVA
8 x Storage Bay * 6.1kVA = 48.8kVA

Total DMX-4 Power Consumption for 2400 drives = 55.2kVA

V-Max supports 1 System Bay and 11 Storage Bay. Maximum Scalability 2400 Drives(can be flash, FC or SATA)
1 x System Bay * 7.8kVA = 7.8kVA
10 x Storage Bay * 6.1kVA = 61.1kVA

Total V-MAX Power Consumption for 2400 drives = 68.9kVA

This proves EMC is greenwashing the lower power consumption. If you dont know what is greenwashing click here http://en.wikipedia.org/wiki/Greenwashing
