You implement FAST VP on an existing EMC VNX. The Extreme Performance pool holds 5% of
usable storage, the Performance pool holds 20%, and the Capacity pool holds 75%. The Tiering
Policy is set to Auto.
The attached hosts run several applications. Some applications access data frequently, while
others are write-once read-never. Twenty minutes after tiering is started, the customer reports
there is no performance improvement. How should you respond?
A.
Data relocation involves a warm-up period � the performance benefit is seen over the long
term.
B.
The Performance pool is too large for effective data relocation.
C.
The warm-up period for FAST VP is determined by the size of the Capacity pool.
D.
Three-level tiering is not supported in FAST VP.
