What is the EMC recommended network quality for SRDF/S over GigE?

You are designing an SRDF over GigE solution. What is a consideration to maximize TCP
connection scaling?

When working with Fibre Channel connectivity, which statement is correct about buffer
credits?

You are designing an SRDF/S over Fibre Channel solution. Data centers are 50 km apart
and 4 Gb/s FC links are in place. What is the minimum number of buffer-to-buffer credits
required to maximize the utilization of the links?

What is the maximum recommended distance for an SRDF/S over CWDM deployment?

What is the maximum number of wavelengths that can be multiplexed on a single optical
fiber over CWDM?

What is the effect of block size on response times in an SRDF/S environment?

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

An SRDF/S implementation is being designed. The application is doing 6,000 4 KB IOPS
with 30% writes and uses multiple volumes. Assume that the RA performance limits are
3,800 4 KB IOPS for a Fibre RF adapter. How many RFs are recommended?

You are designing an SRDF/S solution. Network bandwidth can be purchased in increments
of single OC3 (155 Mb/s) links. Data compression is not in use. The workload profile is as
follows:
Total I/Os per second = 30,000
Read block size = 4 KB
Write block size = 4 KB
Writes = 30%
How many OC3 links should be recommended?
