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

Which encoding scheme is used by 10 Gb/s fibre channel transmission?

What is the purpose of ISL trunking?

A customer needs to configure SRDF/S between two sites 10 km apart. The customer connected
the R1 ports to fabric-A at site 1 and the R2 ports to fabric-B at site 2. The customer does not want
to merge the two fabrics between sites.
What is the recommended solution?

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?
