How would you advise the customer about the next step?
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.

Which advice regarding FAST Cache should be provided to the customer?
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?
What should you tell 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 do 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?
how does BLOB externalization affect the number of drives required for the same workload?
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?
Which VNX feature will address this concern?
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 multi-pathing solution is a viable option for this company?
You are assisting a company with planning a new VMware environment. The hosts will be
connected to a VNX array using two HBAs and two Fibre Channel switches. The host initiators will
be configured in ALUA mode and will have multiple paths to the VNX.
The customer wants to take advantage of the multiple paths for increased performance. Any
trespassed LUNs should be handled without manual intervention from their SAN administrator.

Which statement is correct?
A customer new to EMC, is upgrading from a simple JBOD array to a VNX array. They plan to
deploy MS Exchange 2010 on the VNX and have asked you for recommended best practices.
Which statement is correct?
which applications’ LUNs should you recommend FAST VP be enabled?
A customer will connect Oracle OLTP and Oracle DSS servers to a new VNX array. They ask if
FAST VP should be enabled for each application’s LUNs.
