About Flexible Storage Sharing

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 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.

FSS allows growing the existing storage by growing the LUN, which is termed as Dynamic LUN Expansion (DLE). To use the DLE feature, you invoke the vxdisk resize command with the length option from the master node in an FSS configuration. Alternatively, you can use the Management Server console of InfoScale Operations Manager to resize a disk, which internally invokes this command. The command intelligently detects the remote disks and gets the required protocol executed to complete the LUN expansion; you don't need to specify any additional options. No explicit master switching is required.

Note:

Do not resize an LVM disk or any other disk on which the OS is installed.

For details on growing the existing storage by growing the LUN, refer to the platform-specific Storage Foundation 9.0 Administrator's Guide.

FSS can be used with SmartIO technology for remote caching to service nodes that may not have local SSDs.

FSS is supported on clusters containing up to 64 nodes with CVM protocol versions 140 and above.

The following figure depicts a FSS environment.
