An application hosted on the Symmetrix is experiencing increasingly longer processing times.
However, the data has not changed in several months. New servers are being added regularly to the array, some of which are also experiencing poor performance.
Performance Manager shows an unbalanced back-end. How could this be resolved?

A.
Move the application’s LUNs to more lightly utilized disks to bring overall response time down

B.
Double the number of drives on the director loop to increase the available capacity

C.
Double the size of the drives used to reduce overall drive capacity usage

D.
Adjust the application I/O to a larger size to increase its throughput while reducing IOPS
