Question #14 (Topic: )
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?
