A customer has an existing VNX system and plans to add more disks. They are using AVM in a
production environment and need the same level of performance that they currently have.
What is the recommended way to expand the system capacity?

A customer is interested in the spin-down feature of their new VNX array. However, they cannot
get the feature to function. Their current drive configuration consists of a pool of 32, 2 TB NL-SAS
drives for their backup-to-disk application.
Why is the spin-down feature failing to run?

You have been tasked with designing the storage layout for a VNX7600 array. VMware hosts will
attach to the array using two HBAs and two Fibre Channel switches. The array will have FAST VP,
SnapView, and FAST Cache installed.
The customer wants to configure FAST Cache with a capacity of 2000 GB. They also want to put
as many drives as possible into a single FAST VP pool while still being able to use SnapView.
Snapshots will be taken each day of 10 x 1 TB LUNs and will be used for backups to tape. Once
the backups complete, the snapshots will be destroyed. The customer insists on using SnapView
due to the backward compatibility with their scripts. The source LUNs will produce less than 20%
change daily.
The array has the following hard drives installed:
— 31 X 200 GB Flash hard drives
— 34 X 600 GB 15K SAS hard drives
— 17 X 2 TB 7.2K NL-SAS hard drives
The entire design should follow EMC best practices.

How should the three tiers for the FAST VP pool be configured?

A customer wants to configure FAST Cache on their VNX storage system. Their working data set
is 600 GB in size. They plan to have sufficient FAST Cache to hold the working data set. There
are currently no Flash drives in the storage system. The customer wants to follow EMC best
practices.
How can this be achieved?

A customer wants to add Flash drives to their VNX array and use them as FAST Cache. They
want at least 250 GB of FAST Cache capacity on each SP. There are no Flash drives in the array
and they want to follow EMC best practices on spare disks. What should be used?

After reviewing the design for a new VNX5800, a customer requests an explanation of the sparing
algorithm used by the array. The following information is provided:
— A RAID group consists of eight 600 GB 10K SAS drives in a 6+2 RAID 6 configuration
— Within this RAID group there are three 125 GB LUNs
— One of the eight drives has just failed
Based upon this information, which spare drive would the array select first to replace the failed
drive?

What is a benefit of VNX FAST Cache?

A customer has an application requirement of 3000 IOPS with a 60:40 read/write ratio and 4.85 TB
storage capacity. The I/O is small-block random. The customer is concerned about cost. You
propose a VNX with 300 GB 10K SAS drives.
If spare drives are not included, which configuration minimizes costs while adhering to EMC best
practices?

Which subnet range should not be used for VNX iSCSI ports because of the static management
service ports?
