A customer recently added a large number of new users to their VNX for Block storage system.
They now complain that the system is slow. You have been asked to fix this problem.
Their configuration uses traditional LUNs exclusively. They have a number of Flash drives that are
currently unused. Analysis of their application environment shows that several LUNs have skew >
90%.
Which technology would you implement to solve their performance problem?

A.
FAST Cache

B.
FAST VP

C.
Flash RG

D.
Pool LUNs
