Cluster File System (CFS)
CFS enables you to simultaneously mount the same file system on multiple nodes and is an extension of the industry-standard Veritas File System. Unlike other file systems which send data through another node to the storage, CFS is a true SAN file system. All data traffic takes place over the storage area network (SAN), and only the metadata traverses the cluster interconnect.
In addition to using the SAN fabric for reading and writing data, CFS offers Storage Checkpoint and rollback for backup and recovery.
Access to cluster storage in typical SF Oracle RAC configurations use CFS. Raw access to CVM volumes is also possible but not part of a common configuration.
For detailed information, see the Storage Foundation Cluster File System High Availability Administrator's documentation.
