A cost-conscious 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.
Use EMC Avamar to de-duplicate the data and reduce backup windows
C.
Use Dynamic LUN Migration to modify the LUN layout
D.
Permanently adjust cache read/write ratios
