A customer has three production hosts connected to a VNX. Each host has two 150 GB LUNs in
the same RAID 5 (4+1) RAID group. Replication Manager is configured to take SnapView
snapshots of the production host LUNs for local backups using a dedicated backup host. The RLP
(reserved LUN pool) is configured on the same RAID group as the production host LUNs. The

customer reports there are performance slowdowns during backups.
What is the best solution?

A.
Stop the snapshots, remove the LUNs from the RLP, create a new RAID 5 (4+1) group and
new LUNs, and add the new LUNs to the RLP.

B.
Expand the source LUN RAID group to a RAID 5 (8+1) RAID group, and expand the sizes of
the reserved LUNs to twice their original value.

C.
Create a new RAID 5 (4+1) RAID group, create new LUNs on the RAID group, and perform a
LUN migration on the RLP LUNs to the new RAID group.

D.
Stop the snapshots, create a new RAID 1/0 (2+2) RAID group, create new LUNs on the new
RAID group, and migrate the RLP to the new LUNs.
