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 company needs to create clone LUNs on a VNX storage system. These LUNs will be used
by Replication Manager to back up a Microsoft Exchange server database and log LUNs.
Where must the clone LUNS be created to have the least impact on the Exchange servers?

A storage administrator with a VNX Unified solution is using the CLI to monitor the 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 accelerate and ease the
monitoring tasks.
What is the most suitable solution?

Your customer wants to use a SnapView snapshot as part of their backup strategy. You
need to determine whether or not the proposed RLP configuration will meet the performance
requirement. The source LUN performs 400 random 8 KiB IOPS, with a 3:1 R/W ratio.
At what rate is chunk data written into the RLP when the session starts?

You are conducting an analysis of a Celerra system to migrate the data to a new VNX
Unified storage system. You want to measure the current connections for the CIFS/NFS
protocol.
Which “server_stats” statistic type would you use to get the desired information?

A customer with a VNX for File system has a mix of Windows and Linux clients. The
Storage Administrator wants to track and examine different types of correlated statistics for
their file system read and write operations.
Which correlated statistic can accomplish this job?

You are working with a customer to design a VNX for Block solution for their SQL database.
They currently have a CX4-480. In the past they have co-located their database and log
files. In the new VNX design, the database will be placed in a FAST VP enabled pool. The
transaction logs will be placed on a traditional RAID Group. Your customer needs help
determining the number of IOPS they need to satisfy the needs of their transaction logs.
You know the following:
Transaction period: 8 hours (business day)
ThrougEMCut during transaction period: 240 GB
How many IOPS will the transaction log volume require?

A VNX storage system is being configured to provide storage for an Exchange 2010
implementation for 2,000 users. iSCSI will be used for connectivity between the servers and
the array. Each server has two, dual-ported NICs. Based on EMC best practices for
availability and redundancy, how should the interconnectivity be configured?

Your customer has LUNs with a total size of 20,000 GiB. The total I/O load is 15,000 IOPS,
with a 4:1 R/W ratio. Analysis of your customer’s data indicates that data skew is 90%. RAID
5 is used exclusively in the environment.
How many 200 GB Flash drives would be needed to handle the load of the working data
set?

A customer has recently implemented Microsoft Exchange 2010 on a VNX storage system
that hosts a variety of application servers. The Exchange implementation is currently using
RAID 5 striping metaLUNs across multiple RAID Groups. They are using FAST Cache for
the database volumes, but not FAST VP. Performance has been significantly diminished.
What would you recommend to the customer?
