A customer plans to use MirrorView/S as their DR solution. They have slightly in excess of 10 TB
of data to protect, and are concerned about the performance impact of MirrorView/S on their
production data. They are also concerned about the consequences of an accidental fracture on
their environment.
How should they configure their data LUNs?

A customer asked for your assistance sizing a MirrorView/A solution. Following EMC best
practices, which factors would you consider?

A customer has a VNX array replicating to a CLARiiON CX4 array using MirrorView/S. A new VNX
array will be installed and used for testing. A copy of the existing VNX/CX4 data needs to reside
on the new VNX array. Incremental SAN Copy will be used to perform the copy.
What is a valid source LUN for the migration?

A customer has a 300 GB primary MirrorView/S image. The image workload is 5,000 IOPs of
random 16 KB I/Os with a read/write ratio of 4:1. The secondary image is fractured for 20 seconds
as the result of a connectivity failure.
How much data will be copied to the secondary as part of the resynchronization process?

You have advised a customer to upgrade their current CLARiiON storage array before migrating to
a new VNX. The customer would like additional information about what benefits the upgrade will
provide.
Where can information about known and fixed problems for EMC products be found?

A customer wants your assistance in deciding if their existing VNX array can be used to do
backup-to-disk instead of for tape backups. The customer has a VNX Unified storage system that
is fully populated with 125 disks. When looking at analyzer data for the array, you see that it has a
consistent utilization of over 70% on both SPs.
According to EMC best practices, what should be recommended to the customer?

During a data gathering meeting with a customer, a discussion about applications was presented.
Most of the applications are best suited for a RAID 5 pool on the VNX. However, one of the
applications has an I/O requirement for RAID 1/0 spindles.
How should the RAID 1/0 application requirement be handled?

After deploying a new VNX, a customer has asked about features and tools to optimize their
VMware environment. Which tool or feature enables efficient SCSI LUN reservation methods and
reduces I/O traffic during cloning or zeroing operations?

A customer is planning to migrate 14 Microsoft Windows clusters onto a VNX. They want to
preserve all CIFS server names. Using best practices, what should be recommended?
