What is the principle of setting bandwidth for remote replication and LUN copy among storage arrays?
The bandwidth refers to the amount of data that is transferred on a channel in a certain period of time. Its common unit is bit per second (bps). The bandwidth of a computer network refers to the maximum data rate on the network, namely, the number of bits transferred per second. When setting the bandwidth, note the following:
• The bandwidth should be set to meet the requirements of actual services. You can customize a proper bandwidth as required.
• The bandwidth should be set no larger than the current bandwidth of customers' network.
If the workload in the system is heavy, the bandwidth for remote replication and LUN copy among storage arrays can be correspondingly reduced to guarantee the normal running of ongoing services.
