A Symmetrix VMAX 40K customer has recently upgraded the Enginuity level to 5876 Q4 2012 SR.
The customer is interested in implementing the FAST VP compression feature. What is a required
step to enable FAST VP compression?
A.
Ensure FAST VP policy contains at least one tier with a compressible thin pool
B.
Enable compression when associating storage group with FAST VP policy
C.
Ensure that all thin pools in all SATA FAST VP tiers are compressible
D.
Enable FAST VP compression when adding thin pool to tier
Explanation:
I’ll go with D

Fast VP compression is a global parameter, for all policies
But if pool is not compressible, compression won’t happen (even with Fast VP Compression enabled)
The extent must be located in a thin pool that has been enabled for compression
‘A’ seems the right answer to me
