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 10 TB. The customer wants to know if they should continue to use SnapView Snapshots, or should change to using VNX Snapshots. They want you to explain your answer. What do you tell the customer?
