High Availability (HA) with Dual-NAS Failover
Prevent unexpected downtime and data loss.
Build an HA cluster using two TVS-h877AX units — one as the active server and the other as the passive server. When the active server encounters an unexpected failure, the passive server automatically takes over, providing instant protection. This ensures uninterrupted storage services and system availability.
Easily set up, remove, or rebuild clusters via the High Availability Manager application.
Real-time data synchronization between active and passive servers minimizes data loss risk (RPO).
When the active server fails, the passive server can take over within 1 minute (RTO < 60 seconds).
