1/10, 2/8, 3/8, 4/8, 5/8, 6/6, 7/8, 8/8, 9/7, 10/8, 1/8, 12/8, 13/8, 14/8, 15/7, 16/8, 17/6, 18/10
Does it matter that some RSS-sets have an odd amount of disks (what about mirroring/widow disks)? And some RSS-sets has 10 and some has 6 disks?
Is it possible to start the releveling of disks to get as much as possible RSS-sets of 8 disks?
Are RSS-sets created within each diskgroup or is the data from different diskgroups spread over all (and sometimes the same) RSS sets?
many thanks!
Solved! Go to Solution.

SolutionAFAIK is in RSS with an odd number of disks, one disk unused. Every disk in an EVA has a partner disk in the same RSS. If the number of disks is odd, one disks doesn't has a partner and it's ununsed.
Hope this helps,
Best regards,
Patrick

Re: Redundant Set of Storage question
It is unused for VRAID-1 data, but VRAID-0 and VRAID-5 data can be stored on such a disk drive.

Re: Redundant Set of Storage question
A RSS is a subgroup of disks inside a disk group. Information is divided in parts and each part stored, with the RAID overhead, on a RSS.
For the data in vRAID 1, an even number of disks are used, if the RSS has an odd number of disks or disks of different sizes, not all available space will be used.

Re: Redundant Set of Storage question
i was assuming that you can (somehow)manually regroup the RRS sets...
but how is it possible that 2 groups has had a odd amount of disks and some groups has 6 or 10 disks? does it have influence on the performance?
maby a new firmware (from 3.028 to 3.110) will resolve this..
