What utility should you use to investigate performance trends?
You are planning a technical refresh of a customer’s CLARiiON storage array to a VNX. They have stated that the CLARiiON seems to perform slowly and believe that they require additional disk spindles to satisfy their performance requirements.

According to EMC best practices, what do you recommend to your customer?
A customer wants your help in deciding if their existing VNX array can be used to do back up to disk, instead for tape backups.
The customer has a unified VNX that is fully populated with 125 disks. When looking at analyzer data for the array, you see that it has a consistent utilization of over 70% on both SPs.

What key information should be collected to size and configure the VNX for their CIFS shares?
Your customer is looking to consolidate their current Windows CIFS server virtualized on VMware to a purpose built file sharing device. Their environment consists oF.
– 250-300 power users leveraging complex macros and import data from other applications
– 15000-18000 average users leveraging home directories
– Some files are shared between their Windows and Red Hat application teams.

Why are you unable to configure FAST Cache on the array?
You are doing performance analysis on a VNX5100 that is configured with three virtual pools. You determine that FAST Cache would benefit overall performance. Why are you unable to configure FAST Cache on the array?
Where can you find information on known and fixed problems for EMC products?
You have advised your customer to upgrade their current CLARiiON storage array before migrating to a new VNX. The customer would like additional information about what benefits the upgrade will provide.

How would you explain utilization metric to this customer?
A customer is experiencing a performance issue with a specific VNX file system. Analyzer showed that the utilization of several RAID Groups was in the red. The problematic file system, however, was mapped only to one of those RAID Groups, while other RAID Groups served file systems without known issues. How would you explain utilization metric to this customer?
To start your evaluation, what information will you ask the customer’s storage administrator to provide?
A customer is questioning whether their Unified VNX configuration is compliant with EMC VNX best practices. To start your evaluation, what information will you ask the customer’s storage administrator to provide?
