You are proposing a storage solution using VNX to support a Microsoft Exchange 2010 virtual
implementation on Microsoft Hyper-V. You have worked with the customer to understand the
Exchange requirements, which are described in the exhibit. Based on availability, performance,
and Exchange mailbox size requirements, you are recommending RAID 5 with 7.2K rpm NL/SAS
disks.
Following EMC best practices, what is the minimum number of spindles required for this
environment?

Refer to the exhibit.

A junior architect on your team has asked for your assistance in analyzing performance metrics
from a customer’s array. You have been provided with the exhibit, which depicts two devices and
their associated workloads.
Which answer best describes what is occurring?

Refer to the exhibit.

A customer has three SAS DAEs configured with eight 4+1 RAID 5 Groups (RG) 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?

Refer to the exhibit.

A customer is seeking insight about the data access profile on LUN 500, and has provided you the
output shown in the exhibit. The Average Seek Distance (GB) parameter from Unisphere Analyzer
shows a high value relative to the size of the disks that make up the RAID Group on which LUN
500 resides.
What can you determine about the data access profile of LUN 500?

Refer to the exhibit.

What can be concluded from the exhibit about the I/O profile of LUN 600?

Refer to the exhibit.

A customer has three SAS DAEs configured with eight 4+1 RAID 5 Groups (RG) and six Hot
Spares. 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 the second file system creation using Automatic Volume
Management System-defined pools?

Refer to the exhibit.

You are proposing a storage solution using VNX to support a Microsoft Exchange 2010 virtual
implementation on VMware ESXi. You have worked with the customer to understand the
Exchange requirements, which are described in the exhibit. Based on availability, performance,
and Exchange mailbox size requirements, you are recommending RAID 5 with 7.2K rpm NL/SAS
drives.
Following EMC best practices, what is the minimum number of spindles that would be required for
this environment?
