A customer plans to configure their new Symmetrix VMAX 20K. They want your advice on
how to configure a storage pool. This new storage pool will handle random write I/O What
should be your advice about RAID types as they relate to performance?

A.
Use RAID 1 because RAID 5 and RAID 6 will have a higher write penalty.
B.
Use RAID 5 because it can be more efficient for random writes than RAID 1.
C.
Use RAID 6 because both RAID 1 and RAID 5 have a higher write penalty.
D.
RAID type does not matter since everything in the VMAX goes through cache.
