A customer wants advice on how to provision storage for a performance-intensive OLTP application. It has a 3:1 R/W ratio and a maximum 8 KB block size.

What advice do you give them?

A customer wants to create a file system on a metavolume. What is the smallest metavolume that can be used?

You are examining NAR files from a VNX Block system and notice that the I/O has no write burst and overall is very low. The low and high watermarks are currently set at 40/60. What settings would you recommend for the low and high watermarks?

A customer needs to give a host 300 GB of disk space to improve performance. The VNX to be used has three RAID groups available.

– RAID group 1 is RAID 5 (4+1) with 240 GB free
– RAID group 2 is RAID 5 (4+1) with 220 GB free
– RAID group 3 is RAID 5 (6+1) with 250 GB free

The utilization of each RAID group is minimal and all use 300 GB SAS drives. Keeping in mind the best practices, how would you create a metaLUN?

You have collected four Analyzer archives (Day1.NAR, Day2.NAR, Day3.NAR and Day4.NAR) and would like to merge them into one. What is one way you can do this in Unisphere?

In Unisphere Analyzer, what are two possible views when you right-click a RAID group?

What is the best way to set up a FAST VP pool on a VNX Block system running VNX OE for Block (v31)?

Refer to the exhibit.

The array has only the disks shown on the exhibit. All disks in the array are 600 GB 15K drives.
One disk is used as a hot spare.

What is the maximum number of disks you can add to a single pool?

Refer to the exhibit.

This VNX has the disks shown in the front view. They are all 300 GB 10K disks.

What is the maximum number of drives that you can add to a new RAID group in this situation?
