Question
A customer plans to replace a CLARiiON CX4-960 with a new VNX system. The disks on the CX4- 960 are all configured as RAID Groups. The new system will use Pools exclusively. Local replicas are made using SnapView Snapshots, and have required the use of Reserved LUNs with a total size of 11 TB. The customer wants to take a point-in-time-copy every hour from 8:00 am to 5:00 pm. The customer wants to know if they should continue to use SnapView Snapshots, or should change to VNX Snapshots. What do you tell the customer?
Options
- AVNX Snapshots allow more replicas of a LUN than SnapView Snapshots
- BSnapView Snapshots can only be used on Thick Pool LUNs
- CSnapView Snapshots outperform VNX Snapshots on Thin LUNs
- DVNX Snapshots will require an additional Pool for the COFW data
