Multiple production workloads on an EMC Symmetrix array experience performance issues during the backup window. Even though backups are written to SATA devices and production workloads reside on EFD and FC devices, response times for the production hosts degrade during the backup window and quickly recover thereafter.
During the backup window, the Symmetrix is consistently approaching the system write pending limit. What is the best way to provide predictable and controlled service levels for the production workloads?

A.
Create a static Dynamic Cache Partition for the backup workload

B.
Create a static Dynamic Cache Partition for the production workloads

C.
Create a flexible Dynamic Cache Partition for the backup workload

D.
Create a flexible Dynamic Cache Partition for the production workloads
