A company is running their parts inventory applications on an HP 3PAR F400 storage system with
NearLine (SATA) disk drives. These applications are currently using LUN utilizing a Raid 5 (7+1)
NL CPG. They are having performance issues while compiling their monthly reports in a timely
manner. HP 3PAR System Reporter indicates several high write I/O volumes during production
runs.
What should the design team recommend to improve this performance?

A.
HP 3PAR Adaptive Optimization and a new RID 1 CPG

B.
snapshot to capture all writes to a RAID 1 CPG

C.
thin provisioning to achieve a better distribution across all physical disks

D.
HP 3PAR Dynamic Optimization to move the high performance volumes to a new RAID 1 CPG

• Allows for large-scale performance optimization after adding new resources to the system or
moving a large number of volumes between tiers
