A storage administrator asks for help in redesigning the backup environment. The current
environment has a CX4-120 that hosts data for multiple applications. The CX4-120 has 120 disks
and is at 75% capacity utilization. Performance statistics from Navisphere Analyzer show that the
CX4-120 is consistently at 75% utilization for all resources.
What should your next step be?

A.
Inform the storage administrator that the array has neither the performance nor the capacity to
support snapshots or clones

B.
Calculate the change rate of data on the hosts for IOPS performance requirements

C.
Suggest clones and ensure the clones and clone private LUNs use separate disk groups than
the source LUNs

D.
Suggest snapshots and calculate the amount of storage for the required reserved LUN pools
