A customer has deployed a new application on a host using VNX storage. The new application I/O
size is 512 KiB, has a 50/50 read-write ratio, and its write behavior is sequential and bursty. All

other host applications are characterized by 4 KiB I/O random writes.
The customer has noticed degraded overall VNX performance during write bursts, which is caused
by the new application. Your analysis reveals a high rate of forced flushing, as well as significant
CMI congestion.
What can you recommend to improve overall VNX performance?

A.
Decrease the write-aside value

B.
Disable write back cache

C.
Increase the read cache area

D.
Enable mirror cache
