A customer wants to improve write performance on their FAS2552 HA system. The system
is built with SAS drives, and they are not interested in purchasing additional disk shelves.
The workload consists of mostly small, random overwrites and random reads.
What should the customer do to improve performance?
A.
Enable free space reallocation on the aggregate.
B.
Enable FlashCache on both nodes.
C.
Increase the amount of NVRAM in the system.
D.
Assign a Flash Pool RAID group to the aggregates.
Explanation:
A Flash Pool is built from a Data ONTAP aggregate in a two-step process,
described in section 3,1, “7-Mode CLI.” Essentially it is the addition of SSDs into an
aggregate to provide a high-bandwidth, low-latency location that is capable of cachingrandom reads and random overwrites.

For me it must be a.
Because the costumer wouldn´t buy a additional shelf
