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 for RAID 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.
