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 overutilization 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?
