If you plan to use Resiliency Platform Data Mover for replication of data in your environment, you need to deploy and configure at least one Replication Gateway in your production as well as recovery data center.
The Replication Gateway component of Veritas Resiliency Platform is a staging server that aggregates and batches data from multiple virtual machines during replication. The Gateway also performs data optimization like write cancellation. The Gateway on production data center is always paired with a Gateway on recovery data center. The recovery data center Gateway is a staging server that applies the data on the recovery data center storage.
Each Replication Gateway includes the following components:
I/O receiver
Receives the application I/Os that were tapped and sent by the application host in a continuous fashion.
Transceiver
Transfers and receives data over the WAN link periodically.
Applier
Applies the data to the storage after it is received on the cloud Gateway.
Scheduler
Manages the jobs and policies in the Gateway.
Engine
Maintains the state of replication and also coordinates with all other components.
During the deployment of the Gateway, the Gateway is registered as an asset to the respective IMS.
