A Storage Administrator with a VNX Unified solution is using the CLI to monitor 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 make statistical groups to accelerate and
ease the demanded monitoring tasks. Which command must be used to accomplish this
job?

A customer implemented SAN Copy with default settings to create full copies of 60 DMX
array volumes on a VNX storage system. After several hours, they determine that the
process is taking much longer than expected.
Which setting change on the storage system will improve performance?

A company has two data centers. They run multiple Exchange servers in each data center in
a virtualized environment. The Exchange Admin would like the storage for each Exchange

server to be configured to provide the most flexibility for migrating virtual machines between
physical servers. VSS tools for application consistency compatibility needs to be maintained.
How should the storage for the Exchange virtual machine be allocated to the hypervisor?

A customer has installed a VNX storage system for their VMware cluster based environment
with six ESX hosts. The ESX will be dedicated for MS SQL servers supporting two heavy
SQL online transaction processing applications with multiple instances and 16 single SQL
instance applications. You are designing the scaling approach scope for those ESX hosts.
What is your recommendation in scaling the deployment of SQL servers?

You have designed an Auto-tiering solution using Flash, SAS, and NL-SAS disks in your
storage pool. Your design was implemented and scheduling has been running daily. The
customer reports that there is no data in the NL-SAS tier.
Why is this the case?

A customer is concerned about the VNX Unified storage performance. The VNX provides
storage services for variety of Windows and UNIX application servers. When monitoring the
switches they notice heavy traffic between the servers and the storage.
The LUN analysis yields the following results:
$ /nas/sbin/naviseccli -h spa getdisk 1_0_4 -rds -wrts -bytrd -bytwrt
Bus 1 Enclosure 0 Disk 4

What is the I/O size being used to send data to disk?

You are designing a VNX storage solution for an Oracle database implementation. The VNX
is populated with Flash, SAS and NL-SAS drives. The customer has asked you to
recommend the optimal disk layout for the Oracle Automated Storage Manager instance disk
group.
Which recommendation best conforms to EMC best practices?

Your customer has a Microsoft SQL installation on a VMware guest Windows 2008 Server
using VMFS. The ESXi server uses a VNX system. The VMFS has been properly aligned
with the physical disk.
What would you recommend to your customer to avoid misalignment between a partition
used by the Windows 2008 Server and the underlying physical disk?

A VMware Administrator has received numerous reports from his users about performance
degradation. The administrator believes that your storage design on the VNX is the reason
for the symptoms.
You ask the administrator for an esxtop analysis of the affected ESXi server. When you
examine the report and notice that the value on the Load Average Line is 2.00.
What would you report back to the administrator?

Your customer wants to enable file deduplication on an existing data-populated VNX for File
system, based on the following specifications:
Moderately busy file system scan rate: 500 files per second
Moderately busy file system ingest scan rate: 5 MB/sec
Number of files: 1 M
Average file size: 50 KiB
Estimated deduplication: 30%
How long will the initial deduplication take to complete?
