  • Page 19: Communicating Directly With A Remote Cluster

    Communicating Directly With a Remote Cluster Applications may communicate with a remote DX Storage Cluster during local-cluster disaster recovery. For an application to communicate to a remote DX Storage Cluster, the DX Cluster Services Node on the remote public network must be addressed. A proxy server on the DX Cluster Services Node (on the local cluster) accepts HTTP requests from the application and forwards them to a DX Storage Node in the DX Storage Cluster.
