Understanding SCVMM LUN allocation

TRYAREBOOT · ‎2014-05-13

We are running SCVMM on a Cisco UCS with a FAS3220 with both shelves filled there a mix of HDD and SSD in each so we have 2 aggregates one on each shelf utilizing flash pools. Each aggregate is approximately 17TB.

We have created a bunch of LUN's from within SCVMM utilizing the SMI-S provider and they are mounted as clustered shared volumes but they only seem to add up the approximately half the capacity of the aggregate yet we cannot create any more?

I am sure there must be a valid reason for this but I don't seem to be able to find it!

Can anybody enlighten me?

Thanks

Andrew

So does nobody else on here run with a similar config then? Or possible I am asking in the wrong place?

Thanks

Andrew,

Could you please tell us the capacities of HDD and SSD drives. Also, give us the sizes of all the luns on the aggregates?

Please send us the trace/log files of the agent also.

OK here is some more detail.

So my 1TB LUN appears to be taking over 2TB of space

Looking at the volumes I see that vol1 was created to store the LUN in. Looking at the details of that.

So for my 1TB LUN a vol has been created with autogrow enabled consuming more than twice the capacity I needed.

I have a the trace log but its rather big. This piece seems to most relevant

I know this was back in May but we are still plagued with this issue. Any pointers on how to procede? Should I just log a support incident?

I have not used the SMI-S plugin but it would appear that the volume created is sized according to traditional thick provisioning rules. LUN size x2 +snapshot space. So for a 1TB LUN you need 2TB volume plus snapshot space which is typically 20% leaving you with a 2200g volume. This guarantee's space of the entire LUN and 100% overwrite and snapshots.

Have a look and see if you can configure the volume provisioning settings. I suggest reading up on thin provisioning and deciding if you prefer to use that method as it will save space within the aggregate. Just remember if you plan on overcommiting your aggregate you need to have good monitoring in place.

Please raise a support ticket while we reproduce this in our labs.
