SAN Defrag

Hi All,
I have a cluster of Lefthand SANs (4 nodes).
This holds a number of small (25gb) volumes, these are mapped to a Solaris server and mounted as iSCSI drives.

There are about 20 of these that are about to be deleted... my question is does the SAN/IQ OS do any sort of regular defrag? Will all this recailmed space be re ordered?

Re: SAN Defrag

SAN/iQ handles all storage location optimization automatically. So there is nothing you need to do on your end.

You should not see any process run to reorder the space (like a restripe or resync) as placement is optimized on use.

As an aside,ue to this, you never have to (and you never should) run any defragmentation software against SAN volumes.

Hope that helps!

Hi,
LHN product does not "reclaim" disk space either.
