The Unisphere Analyzer data shows all disks in a VNX. Using EMC best practices, what would be the best way of allocating storage from the unbound disks?

A customer has reported degraded performance with several of the applications that run on a VNX. After going through the performance data on the array, you find that all the performance issues are centered around the same RAID 6 group, and that the RAID group is supplying 50 percent less IOPS than before.

What is the most likely reason?

What is the default cache page size in KB on a VNX?

A customer system has the watermark processing disabled. To which value will the low water mark (LWM) default?

When setting up QoS for a host’s LUNs, what software must be loaded on the host system?

A customer has implemented Unisphere Quality of Service to ensure that an application obtains the resources necessary to meet the required service level based on a consistent IOPS level.
However, when the storage administrator reviewed performance of the application, the IOPS were variable and lower than expected. Other applications are receiving exactly the resources defined through the performance policies.
What might be the problem?

A customer maintains a mission-critical database with a small transaction logging file. The customer would like to have the transaction log share array resources with other applications while maintaining a specified response time for the database. What Unisphere Quality of Service control mechanism will provide the necessary functionality?

A customer has an application with a large sequential I/O pattern and wants to design the storage for the best possible performance.

Which design solution would you recommend?

Which three metrics can Unisphere QoS control?

A customer would like to capture a NAR file with 26 hours of data outputted by Unisphere. What should the archive interval be set to?
