An Oracle database is stored on an EMC VNX storage array and replicated to a second VNX array
at a DR location. EMC RecoverPoint is providing the replication.
According to best practices, how many Consistency Groups are required to provide application
consistent recovery?

A customer has placed their user data, consisting of text, Word, and Excel files, on a thin LUN
created from an existing pool. The thin LUN is reaching capacity and cannot be expanded over the

pool due to capacity constraints on the pool.
What is the best way for the customer to reclaim some of the capacity on the thin LUN?

An application owner is concerned about the performance of a set of application servers. The
applications generate a large amount of small I/O. Disk and LUN response times appear to be
acceptable for the servers in question. The servers are all Windows hosts using QLogic HBAs with
the default EMC driver settings.
Which Unisphere Analyzer counter would provide the most useful insight into the issue?

A customer has recently virtualized an Oracle database on a VNX system. Initially, performance
was satisfactory. Now, with more usage there is some performance degradation. You used
Analyzer to check the backend and did not see any problems.
Which VMware best practice would be easiest to resolve the issue?

A customer wants to use Replication Manager (RM) to create local copies of their SQL databases.
They want RM jobs to complete as soon as possible without any interruption to the database.
They also want to minimize the impact on the storage system.
Based upon EMC best practices, which solution would you recommend to address their
requirements?

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, APP-STAGE, 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?
