A VMware 5 customer is planning to upgrade their networking environment to 10 Gb
Ethernet. They would also like to use real time vMotion to ensure balanced application load

distribution throughout their environment. They are also currently running their VMware
environment on 64bit, dual core processors.
What advice would you give to your customer to assist them with the upgrade of their
environment?

You are conducting an analysis of a Celerra system to migrate the data to a new VNX
Unified storage subsystem. You want to collect statistical information about the CIFS
subsystem.
Which “server_stats” statistic type would you use to get the desired information?

Your customer has LUNs with a total size of 25,000 GiB. The total I/O load is 10,000 IOPS,
with a 4:1 R/W ratio. Analysis of your customer’s data indicates that data skew is 95%. 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 with a VNX configured with homogenous pools wants to upgrade the
performance of their array. The customer has a limited budget.
Which approach would you recommend?

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 disks required?

A customer needs to move data from a CLARiiON to a new VNX storage system. Attempts
to configure a SAN Copy session with Unisphere fail. The customer uses Navisphere Secure
CLI to configure the session. The session can be successfully started from Navisphere
Secure CLI but fails just prior to completion each time it is started. What is the cause of the
failure?

A customer is experiencing performance degradation when accessing certain CIFS shares
configured on a VNX for File storage system. To troubleshoot, they would like to create a
report that shows a combination of CIFS and network data.
What command would you recommend that they use?

Your customer has a 2,000 GiB traditional LUN containing a database of customer
information. Data belonging to active customers is frequently accessed, but the majority of
the data is static and seldom used. Your customer wants to implement block compression on
the LUN.
What should your customer be made aware of?

A customer has implemented a VNX array that hosts multiple SQL database applications,
but there are significant performance issues with some of the applications. They have
purchased a small number of Flash drives and have asked for your recommendation on
maximizing performance using the limited number of new drives. What suggestion would you
make about using the Flash drives?

A customer is designing an environment that utilizes thin LUNs on a pool. The customer
makes capacity calculations before they create the thin LUNs, and determine that three thin
LUNs are required. After the customer creates them they experience a capacity shortage.
How much overhead should the customer have calculated into the usable capacity for each
thin LUN?
