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. The Recurring System Data Exclusion Periods chart is used to filter out these hot spots. After running this workload planning for a few weeks, they notice that the selection of records they previously made are showing different numbers than when they started viewing the report, several weeks ago.
What is the explanation for this behavior?
- A. After a week the data of each time slot is refreshed with new data
- B. After two weeks the 84 data points are filled up and the report resets to default
- C. The average of the viewed window has dropped below the best practice
- D. After two weeks the data of each time slot is refreshed with new data
Answer : D
At a disaster planning meeting, an architect is presented with the following facts by a client:
A Unix host is replicating storage from a Production PowerMax to a VMAX 250FX.
RDF pairs have been split with Production and DR hosts accessing their respective storage.
Invalid tracks have started to build against PowerMax and VMAX 250FX.
The client now wants to bring production back to PowerMax, discarding the VMAX 250FX updates while keeping the updates on the PowerMax. What is the correct action to take?
- A. Failback
- B. Establish
- C. Resume
- D. Failover
Answer : A

The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX All Flash array is set to 15%. A TimeFinder SnapVX snapshot is created for a Storage Group containing 10 devices. An application is actively performing read and write I/O to these devices. Allocation for the SRP reaches 85%.
What happens to the snapshot?
- A. Snapshot persists but new snapshot deltas cannot be created
- B. Snapshot fails
- C. Snapshot deltas are allocated from the Reserved Capacity
- D. Snapshot terminates
Answer : D
