A customer has a VNX environment and wants to begin using compression. You have been asked
to perform an evaluation and make recommendations. What would you recommend?

Your customer wants to create a new pool for file and would like you to validate the configuration.

The pool will be created with one RAID1/0 4+4 FLASH drive group and eight RAID 5 4+1 SAS
drive groups. The customer wants to create an even number of LUNs and allowed for auto
assignment of SPs.
What would you tell the customer?

Which criteria is used by AVM when selecting dVols from a traditional RAID group to create a pool
entry?

An enterprise-level customer has recently implemented a pair of bi-directionally IP replicated VNX
systems for their highly transactional CIFS file-based environment and NFS Office systems. Each
VNX has two storage pools of Flash RAID 5, SAS RAID 5, and NL-SAS RAID 6 for source file
systems and SAS. NL-SAS for destination file systems with multiple checkpoints are being taken
each day and retained for 30 days.
After a number of months, they have growing concerns that the replication performance has

degraded. In addition, the amount of free space available in the source storage pools has been
reduced to almost critical levels. They asked your advice on whether to utilize 16 unassigned NLSAS drives to extend the pools or to purchase additional SAS drives.
How would you advise the customer about the next step?

A customer is considering VNX to host their Microsoft Exchange 2010 environment. In particular,
they want to know how FAST Cache will improve the performance.
Which advice regarding FAST Cache should be provided to the customer?

A customer has 20 physical hosts which will be virtualized. They will then be connected to a new
VNX system. All hosts will use virtual disks with a block size of 1 MB.
The customer shows you performance statistics from the physical hosts. You note that they all
perform a mix of 8 kB and 64 kB I/Os. The customer asks what the I/O profile on the new VNX
system will be.
What should you tell the customer?

A customer plans to deploy SharePoint on a VNX array. They ask about the requirements to
implement BLOB externalization.
What do you tell the customer?

A customer plans to deploy SharePoint on a VNX array. They plan to implement BLOB
externalization. Compared to a traditional implementation, how does BLOB externalization affect
the number of drives required for the same workload?

A customer plans to deploy a VNX array to support their XenDesktop environment. They report
1000 desktops are booted on Sunday at 08:00 and are concerned about the number of concurrent
desktop boots causing performance slowdowns.
Which VNX feature will address this concern?

A customer plans to deploy a VNX array to support their VMware View environment. They report
1000 Helpdesk users login daily at 08:00 and are concerned about the number of concurrent user
logins causing performance slowdowns.
Which VNX feature will address this concern?
