About configuring MSDP optimized duplication and replication bandwidth
Each optimized duplication or Auto Image Replication job is a separate process or stream. The number of duplication or replication jobs that run concurrently determines the number of jobs that contend for bandwidth. You can control how much network bandwidth that optimized duplication and Auto Image Replication jobs consume.
Two different configuration file settings control the bandwidth that is used, as follows:
bandwidthlimit |
The bandwidthlimit parameter in the If bandwidthlimit is greater than zero, all of the jobs share the bandwidth. That is, the bandwidth for each job is the bandwidthlimit divided by the number of jobs. If bandwidthlimit=0, total bandwidth is not limited. However, you can limit the bandwidth that each job uses. See the following OPTDUP_BANDWIDTH description. If you specify bandwidth limits, optimized duplication and replication traffic to any destination is limited. By default, bandwidthlimit=0. The
|
OPTDUP_BANDWIDTH |
The OPTDUP_BANDWIDTH parameter in the
OPTDUP_BANDWIDTH applies only if the bandwidthlimit parameter in the If OPTDUP_BANDWIDTH and bandwidthlimit are both 0, bandwidth per replication job is not limited. By default, OPTDUP_BANDWIDTH = 0. See About the MSDP pd.conf configuration file.
