Which factors contribute to response time elongation in an SRDF/S environment?

Using SRDF/S, In Enginuity 5772 and later, How many concurrent writes can a device
receive?

In Enginuity 5671 and earlier, how does SDRF/S behave when multiple writes to a device
are received?

An SRDF/S implementation is being designed. The RA performance limits are 3800 4k IOPS
for a Fibre RF adapter. The application is doing 6000 4k IOPS with 30% writes and uses
multiple volumes. How many RAs are recommended?

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. What should you recommend?

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 ThrougEMCut chart shows that the available througEMCut is greater
than the peak througEMCut. The “Volume Exceptions” table lists ten devices. What should
you recommend?
