What do you advise the customer?
A customer has a pair of VMAX arrays configured to replicate thin devices at one site to thin devices at another site using SRDF/A. The customer wants to implement TimeFinder/Snap replication of the R2 device on the target array and asks you to confirm this is a supported configuration. What do you advise the customer?

How many disks are required for each configuration type?
A customer is deploying a new Microsoft Exchange environment and has requested assistance with the associated disk design. They are deploying Exchange for 850 users with an average of 3 I/Os per user.
They expect a 60% read and 40% write distribution.
The customer would like to know the number of disks required for both RAID 5 and RAID 1/0 DMX configurations with 15k rpm drives. How many disks are required for each configuration type?
What is the most costeffective EMC solution?
A customer plans to create two regional offices that are between 800 and 2,000 km away from their main data center. Each regional office will have a data center that will serve four to six branch offices between 30 and 50 km away.
At the close of business each evening the customer will shut down the application and transmit changes to each regional office. The amount of new information sent from the head office each night will vary from 0.5 and 1.5 GB. Later each night, an application at the regional offices will read the data from the head office and generate approximately 50 MB of new rate information appropriate for its branch offices.

Which initial solution should be considered?
A customer decided to consolidate their storage onto a Symmetrix. They have a mix of Windows and UNIX servers and want one copy of data for creating backups each night. They also want another copy to be made during the day. This second copy will be a standby to perform a fast recovery in the event of data corruption.
during the day and 5. 1 at night. The application appears to be highly sensitive to disk response times during the day.

What would you recommend to solve the performance problem?
A customer has implemented a second Brocade director into their environment. They have moved several hosts and one of their two storage arrays onto the new director. When a large batch cycle was run, the customer experienced queuing on the directors when previously there was none.
The customer discovered the following during their analysis of the issue.
The hosts running the batch cycle used storage from both arrays.
The only LUNs having problems came from the array attached to the new director.
When the batch process was rerun with all LUNs made available through the original director, no problems were encountered.
