About Direct mode replication
For migrating your data center assets to Amazon Web Services (AWS) using Veritas Resiliency Platform, you have an option to choose between two modes of replication: Direct mode and Object Storage mode.
For migrating to a data center other than AWS using Veritas Resiliency Platform, only Direct mode replication is used.
The Replication Gateway on source data center is always paired with a Replication Gateway on target data center. In Direct mode replication, the Replication Gateway at source data center directly communicates with the Replication Gateway at target data center. The source site Replication Gateway acts as a staging server that aggregates and batches data from multiple virtual machines during replication. The target data center Gateway is a staging server that applies the data on the recovery data center storage.
