How Can I Set the Bandwidth for Remote Replication to Achieve the Optimal Performance?
Question
How can I set the bandwidth for remote replication to achieve the optimal performance?
Answer
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). Bandwidth of a computer network refers to the maximum data rate on 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 to a value not larger than the current bandwidth of customers' networks.
If the workload in the system is heavy, the bandwidth for remote replication between storage arrays can be reduced to guarantee the proper running of ongoing services.
