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:

Transactionperiod:8 hours (business day)
Throughput 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?

A customer has created a thin LUN, enabled compression on a LUN Pool, and installed their
Exchange environment. The Exchange application is showing poor performance.
Which workload characteristic of Exchange would produce poor access times on a compressed
LUN?

You are migrating a backup application that runs on physical servers to a VDC. The VDC storage
is currently a VNX configured with NL-SAS drives only. Your customer is concerned about the cost
to achieve reasonable performance. You are designing the VMs that will support the application.
Based on cost, which would be the first solution you would recommend?

Your customer is designing a Proof of Concept with SQL Server attached to a VNX. The storage
design includes seven LUNs on a RAID Group. The system is generally very heavily loaded, with
a particularly high load on the cache. This is a very carefully controlled environment and your
customer has asked for assistance in planning the layout of the LUN location on the physical
spindles.
Where in the RAID Group would you recommend placing the two heavily used LUNs for a “shortstroked” architecture?

A customer is about to implement your VNX for File design for a file-sharing environment. The
design specifies both NFS and Windows clients that access file systems in a multi-threaded
manner. All file systems will be created using the Automatic Volume Manager. The customer is
most concerned with disk efficiency, and wants to use all storage in each pool entry before
creating another.
Which value would you change to meet this requirement?
