SFHA Solutions 6.2 (AIX and Solaris): Share local storage across the network using Flexible Storage Sharing

Cluster File System (CFS) 6.2 brings the Flexible Storage Sharing (FSS) feature to Solaris and AIX environments, enabling you to share Direct Attached Storage (DAS) across nodes in the cluster to run in SAN-free or hybrid modes.

FSS takes advantage of high speed interconnects to allow shared access to local storage enabling you to create logical volumes in both shared and shared-nothing storage configurations, to create a high-performance, highly available shared namespace. With FSS, enterprises can use software to provide data redundancy, high availability, and disaster recovery capabilities, without requiring physically shared storage.
 

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.
