A customer is experiencing performance issues during their anti-virus scanning in their
VMware environment. They have determined the problem to be a storage issue. Full clones
on SAS drives are being used for replicas. All the anti-virus scans must be run during a
limited time window. What can the engineer recommend to alleviate the bottleneck?

A Customer is planning to build a VDI environment on a VNX array. The customer is working
to determine what type of VM replicas would be acceptable in their environment. It needs to
have best performance. What could be recommended?

A Customer is planning to build a VMware DTaaS environment on a VNX array. The
customer is deciding what type of VM replicas would be acceptable in their environment. It
needs to have a small footprint and contain frequently accessed data on SSDs drives. What
should be recommended?

A customer built a VDI on a VNX array. The customer currently has only NL-SAS drives. The
customer wants to simulate I/O characteristics of users accessing the storage from the
virtual desktops. What tool should be recommended?

Click the calculator icon in the upper left-hand corner. A customer is building out a VDI
environment of 1000 light users and 50 heavy users. They plan to use Boot from SAN for all
VDI users. They are preparing a complete HA environment. If boot requires 6300 I/Os, with
5700 write I/Os and 20 seconds to complete. How many I/Os will occur during an HA failover
in this environment?

What factors can be used to determine the number of IOPs per desktop that a VNX will need
to satisfy during the boot of a virtual desktop?

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’s database resides on a RAID 5 Pool with SAS drives. Which best practice
should be followed to optimize Reserved LUN Pool disk performance?

A customer is supporting 800 Exchange users on a VNX5700. The users are divided among
four Exchange storage groups using a total of eight LUNs each for data and logs and two
LUNs for a cluster quorum disk and MSDTC. The company purchased a VNX5300 for its
remote site. The company is using MirrorView/A with consistency groups to ensure
consistent point-in-time recovery. The Exchange LUNs have been added to the consistency
group, but the administrator is having trouble adding the quorum and DTC LUNs. What
should the administrator do?

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