Then, which is the required network bandwidth?

The peak write bandwidth of an application is 10 MB’s, the average write bandwidth is 200 KB’s, and the average write IO size is 4 KB. The overhead of private information is about 11%, and the bandwidth utilization rate is 70%. The network employs FC, and the synchronous remote replication mode (considering the overhead of private information) is enabled.

Then, which is the required network bandwidth?
A . Not lower than 128.4 Mbit/s
B . Equal to 128.4 Mbit/s
C . Lower than 128.4 Mbit/s
D . Not lower than 64.2 Mbit/s
