AFM gateway node

Each cache fileset in a cluster is served by one of the nodes that is designated as the gateway in the cluster.

The gateway node that is mapped to a fileset is called the primary gateway of the fileset. The primary gateway acts as the owner of the fileset and communicates with the home cluster. While you are using parallel data transfers, the primary gateway might also communicate with other participating gateway nodes for data transfer to home clusters.

All other nodes in the cluster, including other gateways, become the application nodes of the fileset. Therefore, any node in the cache cluster can function as a gateway node and an application node for different filesets based on configuration of the node.
