Which Unisphere Analyzer metric is most useful when determining whether an application’s
read IO access pattern is random or sequential?

Which Unisphere Analyzer metric would you compare with read cache hit/s to determine
whether an application’s read IO access pattern is random or sequential?

When designing a VNX Block Pool layout for a high performance application, how should
LUN ownership be assigned?

Why is it important for Pool LUNs to always have the same Default SP owner and Default
Allocation owner?

How do you change the Allocation Owner of a FAST VP pool LUN to match the Default SP
owner?

Your customer has LUNs with a total size of 25,000 GB. The total I/O load is 10,000 IOPS,
with a 4:1 R/W ratio. Analysis of your customer’s data indicates that data skew is 95%. RAID
5 (4+1) is used exclusively in the environment.
How many 200 GB FAST VP optimized Flash drives would be needed to handle the load of
the working data set?

A customer is trying to determine the correct configuration for an application they are
planning to run on a VNX. The application consists of a heavy transactional workload with
high (greater than 30%) random writes. Which drive type and configuration would you
recommend to the customer?

A customer is trying to determine the correct configuration for an application they are
planning to run on a VNX. The application consists of a heavy sequential workload with high
(greater than 30%) writes. Which drive type and configuration would you recommend to the
customer?

A customer has recently migrated an application from one VNX to another via EMCopy
migration. The VNX’s hardware is completely identical but they have been experiencing
performance issues on the new machine. Their workload primarily consists of small random
read access to their file system.
What could be the cause of this?

What is the best practice for configuring VNX OE File SavVol LUNs?
