A customer recently added two new applications to their CLARiiON environment.Application A is a reporting/data warehouse with a performance profile of primarily sequential read activity. Application B is a customer service application with a performance profile containing high numbers of random writes.
When the applications were deployed. The LUNs were created on a sungle 8+1 RAID group.The customer is experiencing performance problems throughout the day. They cannot understand the reason for the problems since only the LUNs for these two applications are on the RAID group and capacity utilization is less than 50%. No other LUNs are experiencing degraded performance at this time. What should the customer do to resolve the performance problem?

A.
Change the Read/Write cache ratio for the affected LUNs

B.
Increase the number of HBAs in the servers to increase bandwidth to the LUNs

C.
Move one of the application LUNs to a new separate RAID grouo

D.
Use the LUN Expansion Wizard to restripe the LUN and add three more disks
