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 sub-system.
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, 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
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?

A customer has a mix of Windows 2003 and Windows 2008 virtualized guests deployed in their
vSphere v4 environment. They have purchased a new VNX array and are also upgrading their
ESX servers from V4.0 to V5.0.
Their VMware administrators are creating the new target LUNs and VMFS file systems for their
datastores. They have noticed that the alignment offset on the new array is not the same as their
old array, so they are concerned about disk crossing on the new array.
How would you respond to the customer?
