I need to create another volume under the another aggregate that only use for RAW DB & Log?
Current aggregate contain other LUN for another datastore and have been configure SnapVault (to another FAS) already.
The SnapManager SQL Snapshots is on Volume Level.
The Aggregate has no matter except disk type and performance.
You should use one seperate Volume with LUN for User DB & LOG, for heavy load you can mount the user db raw lun with a seperate SCSI controller on vmware.
Another Singel Volume with vmfs Datastore for the Server if you will use snapinfo as vmdk drive, the snapinfo snapshot will create a volume snapshot from the whole datastore on every snapmanager backup.
Or you seperate the SnapInfo Disk as seperate Volume RAW LUN and must manual Backup the VM Datastore from the SQL Server.
if you have larger environments you can seperate more things as singel raw lun volume as example every user db / log or Temp db / log.
But if you fine with sql on vmdk now, i think it is no reason for make it complex for only backup and snapvault an db server.
