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

You are designing a Symmetrix VMAX SRDF/S over GigE solution. The production and remote
data centers are 100 kilometers apart. What is the expected write response time delay due to
latency?

You are designing an SRDF/S solution. The workload profile is:
Total I/Os per second = 10000
Write % = 25
Read block size = 8 KB
Write block size = 8 KB

Network bandwidth can be purchased in increments of single T3 (45 Mb/s) links. Data
compression is not in use. How many T3s links would you recommend?

A customer is using SRDF/S to replicate a Symmetrix VMAX at the production site to the VMAX at
the DR site. The sites are connected using a dedicated T1 link and are 38 km apart.
What will significantly improve the link service time between the 2 sites?

You are designing an SRDF/S solution. The workload profile is:
Total I/Os per second = 30000
Write % = 20
Read block size = 4 KB
Write block size = 4 KB
Network bandwidth can be purchased in increments of single OC3 (155 Mb/s) links. Data
compression is not in use. How many OC3 links would you recommend?

When should customers implement SRDF/S solutions?

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?
