Click the calculator icon in the upper left-hand corner. A customer is building out a VDI
environment of 1000 light users and 50 heavy users. They plan to use Boot from SAN for all
VDI users. They are preparing a complete HA environment. If boot requires 6300 I/Os, with
5700 write I/Os and 20 seconds to complete. How many I/Os will occur during an HA failover
in this environment?

What factors can be used to determine the number of IOPs per desktop that a VNX will need
to satisfy during the boot of a virtual desktop?

A customer is running a data warehouse server with dual HBAs connected to a SAN. A
performance analysis of the server shows high utilization. This server needs to be backed up
to a SAN-attached backup device. The customer is concerned about production
performance while backing up the data. Which solution should be proposed?

A customer’s database resides on a RAID 5 Pool with SAS drives. Which best practice
should be followed to optimize Reserved LUN Pool disk performance?

A customer is supporting 800 Exchange users on a VNX5700. The users are divided among
four Exchange storage groups using a total of eight LUNs each for data and logs and two
LUNs for a cluster quorum disk and MSDTC. The company purchased a VNX5300 for its
remote site. The company is using MirrorView/A with consistency groups to ensure
consistent point-in-time recovery. The Exchange LUNs have been added to the consistency
group, but the administrator is having trouble adding the quorum and DTC LUNs. What
should the administrator do?

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

A customer needs to move data from a CLARiiON to a new VNX storage system. Attempts
to configure a SAN Copy session with Unisphere fail. The customer uses Navisphere Secure
CLI to configure the session. The session can be successfully started from Navisphere
Secure CLI but fails just prior to completion each time it is started. What is the cause of the
failure?

Refer to the exhibit.

A large IO spans multiple disks, and 2 stripes.
How will the stripe crossing counter and the disk crossing counter increase?

Refer to the exhibit.

A single small IO spans 2 physical disks.
What will the disk crossing counter increase by?

Refer to the exhibit.

A pre-MCx VNX has three SAS DAEs configured with eight 4+1 RAID 5 Groups and six Hot
Spares as shown in the exhibit. All RGs are unused except for RG 0, which contains the
Control LUNs. All LUNs except for those in RG 0 are the same size.
Which dvols will be selected for file system creation using Automatic Volume Management
System-defined pools?
