What is the impact on response time when multiple concurrent writes to an RDF device arrive from
different FA ports on a Symmetrix VMAX?

A customer is implementing SRDF/S for an application that generates 16000 8K IOPS with 30%
writes. A single RDF port can service 1200 8K IOPS. How many RA should be recommended?

A proposed SRDF/S solution was modeled with BCSD. The model assumed that the Source array
had 2 RFs.
The RA utilization chart shows the maximum utilization at 80%. How many RFs should be
recommended to ensure a successful implementation?

A proposed SRDF/S solution was modeled with BCSD. The model assumed that the Source array
had 4 GigE ports. The RA utilization chart shows the maximum utilization at 70%. How many GigE
ports should be recommended to ensure a successful implementation?

A proposed SRDF/S solution was modeled with BCSD using host-based data.
The BCSD model assumed two engine VMAX arrays with SRDF Fibre ports.
The RA Utilization chart shows a maximum utilization of 45%. The Volume Exceptions table
lists five devices.

A proposed SRDF/S solution was modeled with BCSD using host-based data.
The BCSD model assumed two engine VMAX arrays with SRDF Fibre ports.
The Compressed Throughput chart shows that the available throughput is greater than the peak
throughput. The Volume Exceptions table lists ten devices.

What should you recommend?

A colleague implemented cascaded SRDF for a VMAX technology refresh and site relocation
activity.
The colleague reports they shutdown the hosts at production Site A and copied all data to the
bunker Site B VMAX. But they are unable to enable SRDF/S between Site B and remote Site C.
What should you advise them?

Refer to the exhibit.

A customer has a legacy DMX-3 at Site 1, where a BCV-R1 copy is taken of the production
volumes and then replicated to another DMX-3 at Site 2 via SRDF/A. The customer will replace
the legacy DMX-3 arrays at both sites with new VMAX arrays.
The customer wants to enable concurrent SRDF on the Site 1 SRDF source volumes, to maintain
disaster restart protection between the legacy DMX-3 arrays and migrate the legacy DMX-3 at Site
1 to the new VMAX array. What should you advise the customer?
