Question
A company is planning to deploy synchronous remote replication between two sites over 13 MB/s ESCON links. The two sites are 50 miles apart. The workload profile of the application is as follows:
- Peak work load = 3,000 I/Os per second
- Read/Write Ratio = 70:30
- Write I/O block size = 8 KB
- Current average response time = 5 milliseconds (ms)
- 1 ms latency is added for every 125 miles
If the delay per channel extender is 0.5 ms and one round trip (ESCON) equals four passes, what is the average response time of this solution?
Options
- A1.08 ms
- B2.06 ms
- C4.01 ms
- D6.02 ms
