Veritas Volume Replicator Performance Improvements
Previously TCP was one of the replication protocols used, where one data structure was used to transport the data. This data structure had eight connections which used the bandwidth. These eight connections can be increased and tuned to 16 or 32 to use more bandwidth. However, with one data structure the bandwidth utilization would have very little effect on latency between the Primary host and Secondary host.
Now in this 7.3.1 release, to improve the bandwidth utilization, TCP connections are tuned to multiple data structures to achieve better performance. Every data structure has one transport connection which is set as default, and available all the time. Currently there are 16 data structures available and enabled which are intended to use in parallel. Hence all the data is transited in parallel through these data structure connections, and distributes the network load. If more bandwidth is required, you can tune the existing data structure in the multiple of 16. SeeVeritas InfoScale™ Replication Administrator's Guide for more information.
