What Is the Principle of Setting Bandwidth for Remote Replication and LUN Copy among Storage Arrays

What Is the Principle of Setting Bandwidth for Remote Replication and LUN Copy among Storage Arrays

Question

What is the bandwidth for remote replication and LUN copy among storage arrays be to achieve the optimal system performance?

Answer

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 in the network, that is, 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 reduced to guarantee the normal running of ongoing services.
