A VNX customer is using storage pools and FAST Cache to support a mixed workload
environment. The mission-critical application is SAP with an underlying MS SQL database.
The SQL database has an IO profile that is well suited for FAST Cache. The customer would
like to increase the efficiency of FAST Cache while not degrading the performance in any
way. Cost is not a consideration. What action should the SE recommend to improve FAST
Cache efficiency?

A.
Review the SP Collects and .nar data to determine which pools currently have FAST
Cache enabled. Recommend FAST Cache only on pools that generate small to medium
random IO.

B.
Review the SP collects and .nar data to determine if the FAST Cache is currently at the
maximum supported value. If it is not, recommend adding additional SSDs to FAST Cache.

C.
Discuss the benefits of VNX with MCx in regard to FAST Cache and DRAM cache
improvements.

D.
Request an EMC Customer Engineer perform a comprehensive health check of the array
to determine if any hardware faults exist.
