QNAP's HA solution – Simplifying business continuity from small to large enterprises

QNAP Product Manager, Yung Chou, stated: "Business operations rely heavily on critical digital data and services. As a result, IT infrastructure stability has become increasingly important. QNAP's HA solution integrates automatic failover, real-time data synchronization, and intuitive storage management to provide an easy-to-use deployment option that helps businesses achieve their continuous operation goals."

QNAP NAS Dual-Server Architecture High Availability Solution Advantages

Economical Deployment: QNAP's HA solution is built on the high-reliability ZFS storage system, offering excellent performance and low total cost of ownership (TCO), making it an affordable option for organizations with limited budgets to build a high-availability environment.

Automatic Failover: When the primary server (Active) experiences an anomaly, the standby server (Passive) will automatically take over all services within 90 seconds, minimizing business disruption and loss.

Real-Time Data Synchronization: Through QNAP SnapSync technology, the main/standby NAS can achieve real-time data replication, achieving a minimum recovery point objective (RPO), significantly reducing data loss risk.

Simplified Storage Management: The High Availability Manager application enables IT personnel to easily set and monitor the status of main/standby servers from a single interface, optimizing system management efficiency.

Multifaceted Application Scenarios: QNAP's HA solution can be widely applied to virtualized storage spaces, AI server expanded storage, media video production, and other IT infrastructure configurations, flexibly integrating the reliable data availability and operational continuity required by modern enterprises.

Active-Passive HA Scheme Further Strengthens QNAP's High Availability Portfolio

The launch of the QNAP NAS dual-server architecture high availability solution further reinforces QNAP's product lineup in the high-availability field, enabling organizations of all sizes to achieve business continuity goals with greater flexibility and cost-effectiveness. By combining the ES series enterprise-level NAS with active-active dual-controller architecture and L3 Lite network-grade switches supporting MC-LAG network redundancy, QNAP has built a comprehensive high-availability defense line that spans from storage to network, from single-point deployment to multi-node cluster, comprehensively enhancing the resilience, operational continuity, and market competitiveness of enterprises' IT infrastructure.
