A customer has designed an environment using block based LUNs presented to individual
hosts. They have configured a pool to start using both thick and thin LUNs. One of the
standalone servers is an archive server running on Windows. They want to maximize
capacity on the standalone server since the data is no longer accessed. They have no more
drives to increase LUN capacity.
How can the customer increase available capacity to the archive server?

A customer is checking a NAR file in Unisphere Analyzer. They see that a RAID Group with
only a single LUN is shown with consistently large Disk – Average Seek Distances.
What could this indicate?

A SQL Data Warehouse database is replicating between two VNX storage systems with
Incremental San Copy. The production database is on 15, 15k rpm SAS drives and the
Reserved LUN Pool uses five NL-SAS drives. The database is continuously updated locally
and replicated once a day to maximize the benefits of write folding. Replication takes place
from 6 PM until 10 PM. At 6 PM the storage administrator notices an increase in response
time of the application, which steadily improves until 10 PM. What should be done to
improve performance during replication without affecting recovery data granularity?

A pair of VNX storage arrays is replicating between two data centers over an iSCSI
connection. The SQL Admin has noticed that a small OLTP database with a write size of 4k
periodically experiences increased disk response times. The Storage Admin reports that
during the same period, replication sessions are taking longer to complete. The Network
Admin reports degraded performance between the sites during the same period. Why is the
SQL application seeing increased disk response times from the local array?

You are working with a customer to design a VNX for Block solution for their SQL database.
They currently have a CX4-480. In the past they have co-located their database and log
files. In the new VNX design, the database will be placed in a FAST VP enabled pool. The
transaction logs will be placed on a traditional RAID Group. Your customer needs help
determining the number of spindles they need to satisfy the needs of their transaction logs.
You know the following:
Transaction period: 8 hours (business day)
ThrougEMCut during transaction period: 240 GB
How many RAID 1/0 15K spindles will the transaction log volume require?

Which action would be most effective in reducing the performance impact of a Snapshot on
a Source LUN?

A customer has a VNX system to provide storage for a VMware Cluster with five ESX hosts.
Each ESX host has one dual-port FC HBA connected to two FC switches. They are using

VMware native failover functionality for high availability and load-balancing. The customer
requires higher availability for the ESX host connectivity to the storage system. What would
you recommend to the customer?

A customer would like to configure their VNX for File for the highest possible level of client
availability. There are five Ethernet ports on a single DataMover and a single Ethernet switch
available for client communications.
What availability features would you recommend to the customer?

A customer would like to use five Ethernet ports on a VNX to increase the port and switch
availability. Two non-stackable Ethernet switches are available for the VNX and both support
Full Duplex communications.
How should the customer configure the VNX for the network?

A client has asked for assistance with designing his Exchange environment. The
environment today is fully virtualized and Exchange will be as well. The client is concerned
about local recovery and has decided to make VMware snapshots of their VMFS File system
housing Exchange. The VMware servers are all attached through fiber to a VNX. What
volume type is required to meet the customer’s protection needs?
