Hi,

Yes, it's possible, but we don't recommend you to use a lower speed drive to put the SavVol on performance sensitive file systems. It might slow down the production file system.

This is from "Using SnapSure on Celerra" available on powerlink :

Note: By default, EMC Automatic Volume Management (AVM) algorithms determine the selection
of disks used for a SavVol. AVM tries to match the storage pool for the SavVol with that of the
PFS whenever possible. However, if you do not want to use the AVM selection method, SnapSure
provides the option of specifying any available pool for the SavVol when you create the first PFS
checkpoint. The SavVol can be autoextended as long as space is available on the same disk type.
For example, if the SavVol is built on an EMC CLARiiON® standard (CLSTD) disk, then autoextend
can occur only if space is available on another CLSTD disk. The autoextend feature cannot use a
CLARiiON ATA (CLATA) disk for the autoextend. Use the nas_disk -list command to display the
disk types.

You could store checkpoints in a different pool than the primary file system by creating the savvol in a different pool

You cant set that in the scheduler – you have to manually create the first checkpoint and select the pool there – the others will follow and use the same savvol

Once the schedule is run once and there are more than one checkpoint for that fs you can delete the manual checkpoint

Of course this can have a performance impact

This is how I setup it up and chose a different storage pool, I just wanted someone to confirm my logic. Thanks for your help!
