DX Object Storage Platform Overview 19
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. The DX
Storage Node redirects the requests if necessary, and returns the response
back to the requester.
Communicating With a Cluster Through the Cluster File Server
Applications that do not support HTTP integration with the DX Object
Storage Platform can communicate with DX Storage through the DX Storage
Cluster File Server (CFS). The CFS is an optional node in the DX Platform
ecosystem that extends the DX Platform archiving front-end enablement to
support a network file system for Windows and UNIX clients using CIFS and
NFS protocols.
