When performing a consistent mode change from SRDF/A to SRDF/S, how many cycles does this
process take?

What is supported for the second leg (R21 -> R2) of an SRDF Extended Distance Protection
(EDP) configuration?

An SRDF configuration is running in SRDF/A mode. The customer’s decision to switch from
SRDF/A to SRDF/S is rejected. At which percentage of write cache in use at the SRDF R2 site will
this occur?

When designing SRDF/A, what is the recommended configuration for the DSE pool?

What is a supported mode for disk based Cascaded SRDF?

A Symmetrix VMAX SRDF/A customer is planning to implement DSE.
What are the recommended DA and RA utilization levels before implementing DSE?

A customer is facing intermittent outages on their SRDF/A link. Typically, an outage does not last
for more than 5 minutes. The storage administrator is planning to configure transmit idle along with
the DSE.
Applications on the production VMAX generate approximately 1500 write operations every second.
Assuming that all writes are 128KB in size, how much disk space is required in the DSE pool?

Which SRDF/A feature is recommended for improving resiliency from link outages?

You have been working with a customer on a new SRDF/A design and need to validate the
configuration using host data. Which tool do you use?

Refer to the exhibit.

You have used BCSD to model an SRDF/A solution. Based on the SRDF/A risk analysis shown
what are your recommendations?
