A VSP G1000 Performance Analysis Shows That Server Response Times

A VSP G1000 performance analysis shows that server response times for virtualized volumes are high, 100 ms and higher, but HDD utilization rates in an external HUS 150 never exceed 35%. There are no processor or path constraints in the configuration. The workload is steady and stable. Which two actions will optimize this configuration? (Choose two.)

A) Increase the external path LUN queue depth in the VSP G1000.
B) Spread the server load across more and smaller LUNS per RAID group in the HUS.
C) Break up each HUS LUN into several smaller volumes in the VSP G1000.
D) Migrate the HUS LUNs to RAID groups with faster HDDs.
