SFHA Solutions 6.1 (Linux): Share local storage across the network using Flexible Storage Sharing
Introduced in this release, Flexible Storage Sharing (FSS) 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 you can create logical volumes 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.
FSS is currently supported on clusters of up to eight nodes running Red Hat Linux (RHEL) or SUSE Linux Enterprise Server (SLES). For supported version of RHEL and SLES in this release, see the Symantec Storage Foundation Cluster File System High Availability Release Notes or the Symantec Storage Foundation for Oracle RAC Release Notes.
For more information about FSS, see:
- Flexible Storage Sharing use cases
- Limitations of Flexible Storage Sharing
- Optimizing storage with Flexible Storage Sharing
Installing Storage Foundation Cluster File System High Availability (SFCFSHA) or Storage Foundation for Oracle RAC (SF Oracle RAC) automatically enables the FSS feature. No additional installation steps are required. The fencing coordination points can either be SCSI-3 PR capable shared storage or CP servers.
