CHALLENGE

Addressing Critical MS-SQL Cluster Failover Delays

During infrastructure deployment with the Legacy D brand storage system, D-Company encountered significant performance limitations in its MS-SQL cluster environment. The cluster failover process exceeded 30 seconds, introducing unacceptable service disruption risks for internal database operations.

For a mission-critical internal database environment, such delay posed operational concerns and required immediate improvement. The primary objective was to significantly reduce cluster failover time and ensure stable business continuity.

SOLUTION

Validated Resilience for MS-SQL Clusters with QSAN XF5

To resolve the critical failover bottleneck, D-Company initiated a comprehensive Proof of Concept (PoC) with the QSAN XF5 high-performance storage platform, aiming to validate real-world performance under production-like MS-SQL cluster workloads.

During rigorous validation testing, the XF5 delivered exceptional storage responsiveness and significantly enhanced failover efficiency. Most notably, MS-SQL cluster failover time was reduced from over 30 seconds to under 5 seconds—an improvement of more than 80%, dramatically minimizing service interruption risks and strengthening database resilience.
