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.
