A customer is trying to determine the correct configuration for an application they are
planning to run on a VNX. The application consists of a heavy transactional workload with
high (greater than 30%) random writes. Which drive type and configuration would you
recommend to the customer?

A customer is trying to determine the correct configuration for an application they are
planning to run on a VNX. The application consists of a heavy sequential workload with high
(greater than 30%) writes. Which drive type and configuration would you recommend to the
customer?

A customer has recently migrated an application from one VNX to another via EMCopy
migration. The VNX’s hardware is completely identical but they have been experiencing
performance issues on the new machine. Their workload primarily consists of small random
read access to their file system.
What could be the cause of this?

What is the best practice for configuring VNX OE File SavVol LUNs?

You received a call from a customer asking to help troubleshoot why they cannot select
dvols using MVM from their remaining pool LUNS to create a stripe volume.
What could be a reason for this?

A customer implemented your VNX for File design for a high-performance CAD/CAM
application. The design specified several NFS clients, each accessing a single file system in
a single-threaded manner. You need to guarantee that each file system resides on an
exclusive LUN set. Which value would you change?

Your customer has an application on VNX File storage. The customer allocated the storage
using Manual Volume Management in order to achieve the best performance. The customer
noted that the file system used up all of the storage from the File LUNs even though the size
of the file system is much less than the total of the File LUNs used. Why was all of the
storage used when the file system was created?

You have a VNX customer who is concerned that you created multiple LUNs within the same
Flash drive RAID group and believes this will create disk contention with reduced
performance.
What is the reason to create the Flash drive LUNs in this manner?

You are migrating a database on NFS to a new VNX. The customer notes that you have
designated only SAS drives for the database transaction logs and not any Flash drives. The
customer believes that the Flash drives will greatly increase transaction log performance.
What is the reason that you chose SAS drives?

You received a call from a customer asking to help troubleshoot why AVM cannot select
dvols from their remaining classic LUNS to create a stripe volume.
