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?

Replication Manager (RM) is being used to create replicas for a SQL server installed on VMFS
residing on an ESX server. The operations are sent from a separate virtual RM proxy host.
However, the RM is not able to successfully create copies.
What is the most likely cause of the failure?

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?
