A costconscious customer expressed concern that during backup windows they experience poor performance from their CLARiiON array. However, during the day they have experienced no performance problems. Using NaviAnalyzer, they have determined that the read cache is completely saturated during the backup processes and they believe this is causing the performance problem.
The customer is requesting that you design a solution to resolve the problem. How would you resolve the customer’s issue?

A.
Adjust cache read/write before and after the backup job runs via NaviCLI commands

B.
Permanently adjust cache read/write ratios

C.
Use Dynamic LUN Migration to modify the LUN layout

D.
Use EMC Avamar to deduplicate the data and reduce backup windows
