Your customer has recently purchased a VNX to host their three Oracle RAC database
environments and automated payment processing application. The RACs and application
are differentiated as follows: ORA-PROD, ORA-STAGE, ORA-DEV, APP-PROD,
APPSTAGE, and APP-DEV. The customer has provided you with their Enterprise Storage
Policy (ESP) and is requesting that you adhere to this policy when architecting their new
VNX solution. The ESP states the following as it relates to Oracle database storage
requirements:
All LUNs must be configured as raw devices
All LUNs must be managed using ASM
No fewer than two LUNs per ASM disk group
No more than one database per RAC per RAID Group
No more than three databases per RAID group
All data LUNs must be 1000 GiB RAID 5
All FRA LUNs must be 500 GiB RAID 1/0
No more than eight total disks per RAID Group
No fewer than four disks per RAID Group
Based on the ESP, and assuming ORA-PROD has six instances, what is the minimum
number of RAID Groups required?

You designed the disk layout on a VNX storage system for a large client. They have a very
large amount of basic file data consisting of Word documents and text files. The data needs
to be accessible but sits for long periods of time without activity. You decided to place this
data on a thin LUN and compress it to maximize capacity. The client is concerned about how
much capacity they will reclaim with compression. Based on the data that is going to be
placed on the compressed LUN, what compression ratio will the client typically see?

Your customer wants to expand each back-end bus to the maximum of 10 enclosures
attached via an LCC with an edge expander. They are concerned that it will add extra
latency.
What should be your response?

You are currently investigating a SQL performance issue on a VNX array. You narrow down
the RAID group where the log file resides. You find that the disk response time is 12 ms.
Based on EMC best practices, what should be your assessment of the environment?

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?
