Your customer is adding a new database application. You are asked to design a solution to
expand the current SRDF/S implementation on the customer’s two Symmetrix VMAX arrays
to account for this growth. As part of the sizing, you notice that the two RA ports are at 85%
utilization. What should you tell your customer that the solution requires?

A customer is using SRDF/S with one Symmetrix VMAX in each data center. An application
is doing 10,000 4 KB IOPS with 40% writes and is using multiple volumes. Assume an RA
port can handle a maximum of 4,000 4 KB IOPS. Based on best practices, how many RAs
are needed for this application?

You are designing a Symmetrix VMAX SRDF/S over Fibre Channel solution. The production
and remote data centers are 50 km apart. What is the expected write response time delay
due to latency?

You have used BCSD to model an SRDF/S solution. What information can be obtained from
the model?

An SRDF/S design analysis was performed with BCSD. The Volume Exception tab in BCSD
has identified several volumes. What is a reason for this issue?

A proposed SRDF/S solution was modeled with BCSD. The model assumed that the
source array had two RFs. The RA Utilization chart shows the maximum utilization is 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 is 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 dat
a. 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 be recommended?

A proposed SRDF/S solution was modeled with BCSD using host-based dat
a. 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 be
recommended?

What is a supported mode combination for disk-based Cascaded SRDF?
