ABC.com has identified an application that is not performing within service levels and resides on
Tier 2 storage. The DMX-4 has multiple tiers of storage. Tier 2 storage consists of 300 GB 10k
rpm and Tier 1 storage consists of 146 GB 15k rpm.
Which EMC product can assist the customer in moving the application data from Tier 2 to Tier 1
storage while maintaining application availability?

Exhibit:

A customer is creating a dual fabric topology from four independent switches. Each switch has 32
ports, each operating at 4 Gb/s. The observed loads are displayed in the exhibit.
Based on the information provided, what is the minimum number of ISLs required between each
switch pair?

ABC.com has a number of hosts that generate 1200 IOPS, each with a block size of 4 KB. A Fibre
Channel port on the storage array has a maximum I/O rate of 6,000 IOPS with a 4 KB block size.
What is the maximum number of hosts the customer should attach to one Fibre Channel port?”

A cost-conscious customer expressed concern that during backup windows they experience poor
performance from their CLARiiON array. However, during the day they have experienced no
performance problems. Using NaviAnalyzer, they have determined that the read cache is
completely saturated during the backup processes and they believe this is causing the
performance problem.
The customer is requesting that you design a solution to resolve the problem. How would you
resolve the customer’s issue?

ABC.com is storing data on their primary storage server and using EMC NetWorker to back up this
