XIV Gen3 – No optical illusion

Tiny toast or giant hand?  It not an optical illusion.

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.

If your an existing XIV user and your interested in measuring your current power consumption, check out my tutorial here.   If you want the spreadsheet shown in the video, drop me a comment (your email address will appear in my comments dashboard but will not be visible to anyone else).

    Hi Aussie,

    Can you tell me if it is possible to migrate Data and Interface Modules and all components from Gen2 rack to Gen3 rack?
