In a VNX array with FAST VP enabled, what is the size of the data slice (chunk) that can be relocated between
tiers?

A.
1 GB

B.
2 GB

C.
5 GB

D.
10 GB

Explanation:
For example, if you have Flash (SSD) disks, SAS disks, and NL-SAS disks in the pool, the Flash disks form a
tier, the SAS disks form a tier, and the NL-SAS disks form a tier. Based on your input or internally computed
usage statistics, portions of LUNs ( 1GB slices) can be moved between tiers to maintain a service level close to
the highest performing storage tier in the pool, even when some portion of the pool consists of lower performing
(less expensive) disks. The tiers from highest to lowest are Flash, SAS, and NL-SAS. FAST is not supported forRAID groups because all the disks in a RAID group, unlike in a pool, must be of the same type (all Flash, all
FC, or all SATA). The lowest performing disks in a RAID group determine a RAID group’s overall performance.
