Using multiple AWS DataSync agents for a location
For most workloads, we recommend that you use one AWS DataSync agent for each self-managed location. However, there are exceptions:
-
Some workloads have tens of millions of small files. In these cases, we recommend up to four agents for each location.
-
If your network has limited bandwidth (for example, an agent is on a network link with less than 2.5 Gbps), we recommend four agents for each location.
When using multiple agents for a location, remember the following:
-
All the agents must be online to run your DataSync task.
Note If even one of the agents goes offline, you can't use the location in a task.
-
If you're using a VPC endpoint to communicate with AWS, all the agents must use the same endpoint and subnet.
