Re: Ask the Expert: Advanced Snapshots on VNX

are there cases where you would recommend for someone to use SnapView and not VNX Snapshots ?

Re: Ask the Expert: Advanced Snapshots on VNX

You must use SnapView if you have Traditional Luns, (Luns in Raid Groups).  I would use VNX snapshots for all other uses since it does not have the 2 write penalty that SnapView has (COFW).

VNX snapshots also allows for more that 8 copies, a limitation that SnapView has.

VNX snapshots also uses mount points instead of having to resize the I/O to see the snap lun like SnapView has to do.
