Remember, if you have a physical XMS Management Server, then the first X-Brick would need 7U (Most use virtual so no need for additional 1U). Also as you add bricks you add IB switches (only 2 regardless of brick #s) and Battery Backup Units that change the rack space as well depending on cluster size.
Arindam Paul and Miroslav Klivansky, please feel free to add anything.
Arindam, Itzik or Miroslav,
Someone emailed me person and I want to give the correct answer while adding it to this discussion as well.
This was the question:
Can you ask or if you know, can an XtremIO system be part of a VMAX federated external array configuration?
I want to be sure I answer this correctly and give others to view as well. Thank you in advance.
It was the VMware reference architecture on their site. Page 8 shows 1.9TB usable capacity, all SSD array, 16x200 MLC SSDs — all different from the GA specs.
Here is the updated RA at www.xtremio.com : XtremIO | VMware Horizon View VDI Solution Guide http://www.xtremio.com/vmware-horizon-view-vdi-solution-guide
The RA you mentioned is very old. We will remove it.
