A customer has a VNX system to provide storage for a VMware 4.1 Cluster with 4 ESX
hosts. MS Exchange servers and other application servers will be hosted on VMs. The
customer wants to have the best performance at the VMFS disk/volume level. What would
you recommend when creating boot and email stores using the Virtual Infrastructure client?

You are working with a customer that recently refreshed their hardware with a VNX storage
system configured with Flash drives. During this swap customer also migrated their
Exchange 2010 environment to the VNX. Now the customer is claiming that they do not see
any performance improvement with their Exchange environment.
What is your explanation?

A company recently purchased a VNX storage system to support its clustered SQL Server
environment. You are designing the disk layout.
Based on EMC best practices, what design characteristics should you follow when
configuring SQL Server on the VNX?

A customer is migrating an application to a virtualized environment. After the implementation
is completed they realize that performance is below their expectations.
You are tasked to investigate and recommend an economical solution. Using VMware Tools
and Analyzer on the VNX, you conclude that their application servers are experiencing CPU
over-utilization and storage connection congestion.
What should be your first recommendation?

You have designed a VNX for File solution for a creative content provider. The solution
involves 10, 2 TiB file systems. Each file system has a Checkpoint taken every hour,
refreshed every day. The customer predicted a 2% daily change rate, and SavVol storage
was allocated based on that change rate.
Sometime after the implementation, the customer notices that some of the older
Checkpoints are disabled.
What is the most likely explanation?

Your customer recently upgraded their IP switch hardware. Since the upgrade, the customer
is experiencing performance degradation on certain NFS exports configured on a VNX for
File storage system. The file systems providing the problem exports are all mounted to
DataMovers that have been attached to ports on the new switches as part of the upgrade.
They have engaged you for advice. Which action would you recommend?

A Storage Administrator with a VNX Unified solution is using the CLI to monitor daily storage
performance. They must type long commands to examine the statistical types and names to
get the desired results. You have been asked to make statistical groups to accelerate and
ease the demanded monitoring tasks. Which command must be used to accomplish this
job?

A customer implemented SAN Copy with default settings to create full copies of 60 DMX
array volumes on a VNX storage system. After several hours, they determine that the
process is taking much longer than expected.
Which setting change on the storage system will improve performance?

A company has two data centers. They run multiple Exchange servers in each data center in
a virtualized environment. The Exchange Admin would like the storage for each Exchange

server to be configured to provide the most flexibility for migrating virtual machines between
physical servers. VSS tools for application consistency compatibility needs to be maintained.
How should the storage for the Exchange virtual machine be allocated to the hypervisor?

A customer has installed a VNX storage system for their VMware cluster based environment
with six ESX hosts. The ESX will be dedicated for MS SQL servers supporting two heavy
SQL online transaction processing applications with multiple instances and 16 single SQL
instance applications. You are designing the scaling approach scope for those ESX hosts.
What is your recommendation in scaling the deployment of SQL servers?
