An RLINK is associated with an RVG and establishes the link between the Primary and a Secondary RVG. The RLINK associated to the Primary RVG controls the replication settings such as mode of replication, packet size that is used for replication, latency, or Replicator Log protection and protocol. Each RLINK associated with a Primary RVG represents one Secondary. Each RLINK associated with a Secondary RVG represents a Primary.

The attributes of an RLINK specify the replication parameters for the corresponding Secondary.

A Primary RVG can have up to 32 associated RLINKs. Although a Secondary RVG can also have 32 associated RLINKs, it can have only one active RLINK; this active RLINK represents the Primary that replicates to this Secondary RVG.

Volume Replicator reads data from the Replicator Log volume and sends it to the Secondary. Each Secondary receives data from the Primary at its own rate. For each Secondary, a write on the Replicator Log volume is marked as done when all the Secondary RVGs have successfully received the writes. If a Secondary does not keep up with the write rate, the Replicator Log volume can overflow for the corresponding RLINK.
