StarWind’s Active-Active HA Storage Architecture

StarWind’s Active-Active High Availability (HA) storage architecture uses Synchronous Mirroring (Replication) with Automatic Failover and Failback technology, allowing the SAN to continue operating properly in the event of a node failure.

Automatic failover technology permits you to configure an Active-Active dual node SAN to ensure highly reliable and fault tolerant storage. In StarWind HA Active-Active Failover system, storage data is load balanced across each storage node and, in the event of failure, all storage traffic that was originally intended for the first (failed) node is routed to a remaining node. Both storage nodes continuously monitor each other and failover takes place without any manual intervention from the IT administrator.

The “Heartbeat” feature in StarWind HA guarantees data synchronization between each storage node in a dual-node HA configuration. The Heartbeat eliminates a single point of failure with the SAN nodes by determining which storage node takes priority, while maintaining data synchronization between both nodes.

StarWind Enterprise HA manages synchronous mirroring and active-active automatic failover on a per-volume basis. Because the volume's identity never changes, even in the event when a node or a site fails, your applications and servers experience continuous data availability without a single point of failure.
