A customer is planning on migrating their Exchange data to a VNX array. You have gathered the
following information:
6000 IOPS; 50% read/write ratio
Calculating for RAID 5, what is the minimum number of 15K SAS drives required?

A customer has the following requirements for their ESX environment:
Three 500 GiB datastores
One 1 TiB datastore

–
One 7 TiB datastore
Based on the datastore information, what would you recommend?

After deploying their new VNX, your customer has inquired about features and tools to optimize
their VMware environment.
Which tools or feature enables efficient SCSI LUN reservation methods and reduces I/O traffic
during cloning or zeroing operations?

Click on the calculator icon in the upper left-hand corner. Your customer has the following
requirements for their CIFS home directories:
Checkpoint every 10 minutes
Data retention 24-hours
Self-service file-level recovery
Which checkpoint interval in minutes should you recommend?

A customer has purchased a VNX array and is in the process of allocating RAID 5 (4+1) storage.
They have asked you for best practices on number and placement of LUNs for the Reserved LUN
pool.
Which response provides the best answer?

Click on the calculator icon in the upper left-hand corner. A customer wants to add a SnapView
snapshot to a 500 GiB LUN. Captured data show that the LUN performs 500 4 KiB IOPs with a
read/write ratio of 3:1. What is the expected initial bandwidth at which data chunks will be written
into the Reserved LUN Pool?

Click on the calculator icon in the upper left-hand corner. A customer wants to add a SnapView
snapshot to a 600 GiB LUN. Captured data show that the LUN has an access rate of 1000 IOPs
with a read/write ratio of 4:1, and 8 KiB IOs. What is the expected initial bandwidth at which data
chunks will be written into the Reserved LUN Pool?

A snapshot is being used to perform a backup of the LUN. How can the backup activity impact the
host performance on the source LUN?

A customer would like to implement SnapView but has expressed concern about performance.
Which applications will cause performance issues?

Click on the calculator icon in the upper left-hand corner.
Customer requirements call for a SnapView snapshot to be made of a clone prior to
resynchronization. The source LUN is 256 GiB, and performs 500 random reads/s and 25 random
writes/s of 8 KiB. The clone will be fractured every 15 minutes, and resynchronized after the
snapshot is started.
How many COFWs will be performed each time the clone is resynchronized?
