How many concurrent writes can a device receive?
Using SRDF/S, In Enginuity 5772 and later, How many concurrent writes can a device receive?
how does SDRF/S behave when multiple writes to a device are received?
In Enginuity 5671 and earlier, how does SDRF/S behave when multiple writes to a device are
received?
How many RAs are recommended?
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
What is the impact on response time when multiple concurrent writes to an RDF device arrive from
different FA ports on a Symmetrix VMAX?
How many RA should be recommended?
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?
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 2 RFs.
The RA utilization chart shows the maximum utilization at 80%. How many RFs should be
recommended to ensure a successful implementation?
How many GigE ports 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.
