A customer is using a virtualized environment with a large number of NFS datastores
presented from a VNX system. They are experiencing more than expected network traffic on
their datastore networks. What recommendation would you make to your customer?

A customer recently added a large number of new users to their VNX for Block storage
system. They now complain that the system is slow. You have been asked to fix this
problem. Their configuration uses traditional LUNs exclusively. They have a number of Flash
drives that are currently unused. Analysis of their application environment shows that several
LUNs have skew > 90%. Which technology would you implement to solve their performance
problem?

A customer is running a data warehouse server with dual HBAs connected to a SAN . A
performance analysis of the server shows high utilization. This server needs to be backed up
to a SAN-attached backup device. The customer is concerned about production
performance while backing up the data.
Which solution should be proposed?

A customer has implemented your VNX for File design for a high-performance CAD/CAM
application. The design specified several NFS clients, each accessing a single file system in
a single-threaded manner. You need to guarantee that each file system resides on an
exclusive LUN set. Which value would you change?

An application generates 1000 random 16 KiB IOPS with a R/W ratio of 4:1. An
asynchronous mirror is started on the application LUN. The update cycle is configured to be
20 minutes, and updates take 6 minutes to complete. Assume that the data rate is constant.
What is the minimum space that should be configured for the Reserved LUN Pool on the
secondary VNX?

During a white board session with your customer you explain the benefit of partition
alignment. As an example, you use a 64 K write and explain the difference between a
properly aligned partition RAID 5 4+1 and a misaligned partition. If the partition is
misaligned, how many disk operations will be performed for a RAID 5 4+1 write?

Seven users are trying to simultaneously read different parts of the same file from their VNX
for File storage system. All parts of the file are located on the same physical disk. I/O from
each of the users is sent sequentially to the array.
Which type of I/O workload is likely to be reported by the storage array?

You are designing a VNX for File implementation for a customer. SnapSure Checkpoints will
be used for both backup staging and file restore. The customer would like to place the
SavVols on specific disks, but is concerned that this might make administration difficult.
What would you recommend?

Refer to the exhibit.

Which process is illustrated in the exhibit?

You are proposing a storage solution using VNX to support a Microsoft Exchange 2010
virtual implementation on Microsoft Hyper-V. You have worked with the customer to
understand the Exchange requirements, which are described in the exhibit. Based on
availability, performance, and Exchange mailbox size requirements, you are recommending
RAID 5 with 7.2K rpm NL/SAS disks. Following EMC best practices, what is the minimum
number of spindles required for this environment?
