NEW QUESTION 22
A storage architect is evaluating the performance of a PowerMax array during business hours. They want to know how much extra load the PowerMax can handle without significant performance degradation. The Workload Planner is used to identify the hot spots during the recurring backup windows.
Between 9:30 PM and 1:30 AM and between 3:15 AM and 5:30 AM, backups are causing the PowerMax to exceed the best practice recommendation.
