XIV thin provisioning and compression pools

NickL

Hi,

In our capacity reports for XIV we don't see any configuration regarding compression.
Our XIV202 system has compression enabled, so our virtual capacity exceeds more than 400TB.
Is this function supported in stor2rrd ?



XIV202 pool setup :

Hi,

what is wrkong exactly? We present there numbers which XIV provides us.
Check menu --> storage --> configuration --> text
There should be in the header some capacity data I hope, actually cannot confirm as no access to such box

	Total Soft Capacity     :	462.354 TiB 
	Total Soft Free Capacity:	0.000 TiB

I'm running latest version of stor2rrd and XIV version 11.6.1a

we use totals now (tehere is some cmd which prints it up).
We have used per pool capacity data but this was wrong as there might be some unconfigured raw space which was not included then.
No idea how to do it better.

NickL

Unconfigured raw space is something that can occur on every storagebox, so to my opinion this should not be any particular issue to XIV. I collect additional information from storage pools through the wbem cli.

structure to interrogate ->  IBMTSDS_VirtualPool

Pavel

problem is that sum of free space in pools does not containg unconfigured raw space.
Therefore we use just some total cmd which prints us totals and present it.
