System high availability

A system has several features that can be used to deploy a high-availability storage system with no single point of failure.

Volume mirroring provides protection against a storage system failure by mirroring data across storage systems. For example, for disaster recovery, the Metro Mirror and Global Mirror features can be used to mirror data between systems at different physical locations.

For example, when you use Fibre Channel SAN-attached hosts, attach the node canisters to at least two SAN fabrics, and attach each host system to both fabrics.
