What is the expected initial bandwidth at which data chunks will be written into the reserved LUN pool?
A customer wants to add a SnapView snapshot to a 300 GB LUN. Captured data shows that the
LUN performs 200 random 4 KB writes per second.

how much capacity will the SavVol be extended when the High Watermark is reached?
Your customer wants to increase the length SnapSure snapshots are being kept but is concerned
about having the available capacity to extend the SavVol Space. The file system is currently 350
GiB in size and the SavVol is 20 GiB in size.
By how much capacity will the SavVol be extended when the High Watermark is reached?
which way do VNX Snapshots differ from SnapView Snapshots?
In which way do VNX Snapshots differ from SnapView Snapshots?
Which VNX local protection product provides redirect on writes, point-in-time copies for block LUNs?

LUNs?
What are they?
A customer is purchasing EMC AppSync software and additional VNX array capacity to create
application consistent replicas of their MS Exchange databases using Microsoft Volume Shadow
Copy Service. The Storage Administrator asked for a review of the command signals and data
flows during the backup process. What are they?

What do you tell the customer?
A customer plans to replace a CLARiiON CX4-960 with a new VNX system. The disks on the CX4-
960 are all configured as RAID Groups. The new system will use Pools exclusively.
Local replicas are made using SnapView Snapshots, and have required the use of Reserved
LUNs with a total size of 11 TB. The customer wants to take a point-in-time-copy every hour from
8:00 am to 5:00 pm.
The customer wants to know if they should continue to use SnapView Snapshots, or should
change to VNX Snapshots. What do you tell the customer?
