Open-E - Automatic Failover for NAS volumes.

Open-E delivers automatic NAS (NFS) failover, using two nodes set up in an active-passive configuration. You can buy it as Data Storage Software V6 extension called Feature Pack - NAS (NFS) Failover

Open-E DSS V6 provides fault tolerance via synchronous NAS Volume Replication for NFS shares. Once configured, all data written to the primary server is mirrored to a secondary server. In the event the primary server fails, Open-E DSS V6 automatically switches operation to the secondary server. NFS locks are also reassigned to the secondary server after primary server fails.

This functionality requires the purchase of a feature pack. A single license of the feature pack will enable two licensed full version copies of Data Storage Software V6 to operate as a failover solution.
