Just looking at Fusion and comparing a FAS 2750 with 2 x DS224c and 72x 10K RPM drives to a C30 with 12 x 15.3 SSDs
Under Environmentals
Typical
FAS is 8,021 kWh/Year
C30 is 6627 kWh/Year
Under Median Usage
FAS is 5504 kWh/Year
C30 is 6627 kWh/Year
FAS is 2141 BTU/hr
C30 is 2580 BTU/hr
I would of thought a FAS 2750 with 2 x DS224c and 72 10k RPM drives would use a lot more power than a C30 with 12 SSD ?
