As per the business requirement I need to calculate a bandwidth for Rx(Response) between DC and DR.
I have calculated the BW required for Tx(Request) based on Redo data volume. Please see the calculation below based on average 150MB data generation and transfer between DC and DR.
Redo volume - 150MB/hour
Adding 10% Overhead for Network Protocol framing - 150+(150*.1) -> 168.3
Bandwidth in MBps (Bytes) -> 168.3/3600=0.05
Bandwidth in Mbps -> 0.05*8=0.37
Required Link BW with 20% utilization overhead -> 0.37+(0.37*2) =0.45
0.45Mbps is the BW required between DC and DR for Tx (Request packets).
Likewise, I need to calculate the BW for Rx(Response packets). It's an Active-Passive DC-DR setup.
