A customer has a VMAX 1 Engine with 128 GB of cache. The disks are configured in RAID 1 and
SRDF is not implemented. The applications on the VMAX perform heavy writes with a ratio of
20/80 (Reads/Writes). Due to continuous rate of writes, the VMAX reaches the Device Write
Pending Limit.
What is the most cost effective way to address the problem?

A.
Add cache on the VMAX

B.
Spread write activity to more devices

C.
Migrate from RAID 1 to RAID 5

D.
Migrate from RAID 1 to RAID 6
