You are designing a new VMAX array. The customer’s primary concern is maximizing capacity
available to the host. What RAID protection should you recommend?

What is a best practice when configuring a Symmetrix VMAX for optimal performance and cost?

You are proposing a new VMAX array with FAST VP. The customer reports their application
needs a small amount of EFD capacity and asks whether 200 GB EFDs or 400 GB EFDs would
provide better overall performance. Which drive size do you recommend and why?

A Symmetrix VMAX has been configured with Dynamic Cache Partitions.
What is a criterion that must be met for a cache slot to be eligible for donation?

A Symmetrix VMAX hosts four applications. Each application is assigned a named dynamic cache
partition. Two of the partitions are static and two are flexible. The write pending limit for each
partition is set to 60%.
What will happen if an application running in a flexible partition reaches the write pending limit set
for that partition?

A Symmetrix VMAX hosts four applications. Each application is assigned a named dynamic cache
partition. Two of the partitions are static and two are flexible. The write pending limit for each
partition is set to 60%.
What will happen if an application running in a static partition reaches the write pending limit set
for that partition?

A customer is using virtual provisioning on a Symmetrix VMAX which is being shared for
Production and non-production workloads.
What can be used to separate the different workloads?

You are designing a new VMAX implementation. All applications will share physical drives and
participate in SRDF/S replication.
The customer has two high I/O applications used for OLTP and a several low I/O applications
used for testing. The customer wants to ensure the high I/O applications take precedence over the
low I/O applications on the VMAX array. What do you recommend?

Which condition results in effective prioritization by Symmetrix Priority Controls (SPC)?

A storage administrator receives a warning message that one of the thin pools in the Symmetrix is
low on storage space. The pool contains a large number of thin devices that have been fully
preallocated but have small amounts of used space. What is the least disruptive and most cost
effective way to make more thin pool space available?
