About Flexible Storage Sharing
Flexible Storage Sharing (FSS) is a feature of Storage Foundation Cluster File System High Availability (SFCFSHA) that enables network sharing of local storage, cluster wide. The local storage can be in the form of Direct Attached Storage (DAS) or internal disk drives. Network shared storage is enabled by using a network interconnect between the nodes of a cluster.
FSS allows network shared storage to co-exist with physically shared storage, and logical volumes can be created using both types of storage creating a common storage namespace. Logical volumes using network shared storage provide data redundancy, high availability, and disaster recovery capabilities, without requiring physically shared storage, transparently to file systems and applications.
Refer to the Storage Foundation and High Availability Solutions Software Compatibility List for information on FSS support by your SFCFSHA version and platform.
