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?

A proposed SRDF/S solution was modeled with BCSD using host-based data.
The BCSD model assumed two engine VMAX arrays with SRDF Fibre ports.
The Compressed Throughput chart shows that the available throughput is greater than the peak throughput. The "Volume Exceptions" table lists ten devices.
What should you recommend?
