When IBM offered 2 TB drives on the XIV, I thought I was seeing an illusion: the overall power consumption had dropped (not risen). Guess what? With XIV Gen3, power consumption drops yet again.
Using worst case power consumption numbers I can see the following maximums:
180 drive XIV Generation 2 with 1 TB drives(79TB usable): 8.4 kVA 180 drive XIV Generation 2 with 2 TB drives(161TB usable): 7.1 kVA 180 drive XIV GEN3 with 2 TB drives (161TB usable): 6.7 kVA
So with every update to the product, power consumption has kept dropping. Lets compare the first Generation 2 to the XIV Gen3:
- Usable capacity up by 103%
- Power consumption down by 20%
- Heat output down by 20%
- Noise level down by 33%
- Performance up by up to 400%
How about this as a measure: lets compare the Microsoft Exchange ESRP report for XIV Generation 2 found here with the newly released report for XIV Gen3 found here. While the ESRP program is not a bench marking program, the results are truly impressive.
