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:
Transactionperiod:8 hours (business day)
Throughput during transactionperiod: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?
