Your customer is migrating from a VNX to a VNX with MCx. Based on their workload, 16 KB
constant prefetch sizes were configured on the VNX to improve performance. The customer
wants to implement the same configuration on the VNX with MCx.
What is the smallest prefetch size on VNX with MCx?

A VNX block-only customer is requesting a performance evaluation of their array. The
storage administrator asks you what files you will need to perform the assessment. The
customer does not have Analyzer licensed. How do you respond?

How many threads should be used to provide the best performance to a sequential file
system spanning a single 4+1 RAID 5 LUN?

In designing a disk layout with multiple disk types, which metric should be used for data
locality?

A LUN has the following settings:
Prefetch TypE. Variable
Prefetch Multiplier: 4
Segment Multiplier: 4
Prefetch DisablE. 4097
Write-aside SizE. 2048
Maximum Prefetch: 4096
What is largest write that will be cached?

What size must an I/O exceed for Write Bypass to occur in an EMC VNX with pre-MCx
architecture?

What would happen if both watermarks are lowered in a bursty workload environment with
EMC VNX?

You are being asked to help a customer that is having issues with their new OLTP
application that they have just connected to their existing VNX. The OLTP Administrator has
created a 2 TB pool LUN on 8 NL-SAS drives in a 6+2 raid 6 configuration. The customer
does not have the budget to purchase more hardware this quarter but does have a mixture
of SAS and NL-SAS drives you can use. What configuration would you recommend to the
customer?
