Key highlights of QNAP Dual-NAS HA solution

• Cost-efficient: QNAP HA offers ZFS-based storage with a low total cost of ownership (TCO), making it accessible even to budget-conscious organizations.
• Automatic failover: In the event of a failure in the active server, the passive server takes over seamlessly in less than 90 seconds, avoiding costly downtime.
• Real-time data synchronization: Powered by SnapSync technology, QNAP HA ensures consistent, real-time replication of data between NAS units (minimal RPO), minimizing the risk of data loss.
• Simplified cluster management: The High Availability Manager application allows IT teams to easily manage clusters, monitor system health, and administrate both NAS units through a centralized, user-friendly interface.
• Versatile use cases: From virtualization storage, AI server expansion storage, to media production storage, the QNAP HA solution fits seamlessly into diverse IT infrastructures.
