Where can a storage administrator createvolumes in Unisphere for VMAX?

• A.System Tab
• B.Host Tab
• C.Storage Tab
• D.Security Tab

A proposed SRDF/S solution was modeled with BCSD. The model assumed that the source array had two RFs. The RA Utilization chart shows the maximum utilization is at 80%.
How many RFs should be recommended to ensure a successful implementation?

• A.3
• B.6
• C.4
• D.2

What is the best practice for adding Flashdrives, per engine, on a VMAX3?

• A.Multiples of 8 RAID 6 (6+2) Flash drives
• B.Multiples of 4 RAID 6 (6+2) Flash drives
• C.Multiples of 8 RAID 5 (3+1) Flash drives
• D.Multiples of 4 RAID 5 (3+1) Flash drives

You are designing an SRDF/S solution. Network bandwidth can be purchased in increments of single OC1 (52 Mb/s) links. Data compression is not in use. The workload profile is as follows:
Total I/Os per second = 30,000 Read block size = 4 KB Write block size = 4 KB Writes = 30%
How many OC1 links will provide sufficient bandwidth?

• A.6
• B.4
• C.1
• D.2

The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storage Group containing 10 devices. An application is actively performing read and write I/Os to these devices. The snapshot is linked to the target in Copy mode. Allocation for the SRP reaches 85%.
What will happen to the copy process?

• A.Tracks required for the copy will be allocated from the Reserved Capacity
• B.Copy to the target will fail
• C.Copy to the target will halt
• D.Copy to the target will continue and complete
