Accelerating AI, Database, and Virtualization with Proven High-Availability Architecture
Taipei City, Taiwan – October 28, 2025 – QSAN Technology Inc., a leading provider of innovative data management solutions, proudly announced latest XN4 Unified NVMe Storage Series has received high praise from StorageReview, one of the most influential technology media outlets in the United States. The review commended the XN4 for its exceptional NVMe performance, ultra-low latency, and effortless deployment, noting that it delivers data-center-class performance across AI, media production, and virtualization workloads—further reinforcing QSAN’s position as a technology leader in enterprise storage innovation.
AI-Optimized Architecture with NVIDIA GPUDirect Storage
When paired with NVIDIA H100 GPUs, the XN4 Series achieved ≈11 GiB/s reads and microsecond-level latency through Magnum IO GPUDirect Storage, enabling GPUs to access NVMe data while bypassing CPU bottlenecks directly.
With this architecture, QSAN enables deterministic performance and latency-sensitive data access across AI inference, HPC, and real-time analytics pipelines—from the edge to the data center.
Data-Center-Class NVMe Performance over Ethernet
In StorageReview’s testing, the dual-active, all-NVMe XN4 Series achieved record sequential throughput and sustained responsiveness across both NVMe-oF TCP and RDMA configurations—demonstrating enterprise-grade performance on standard Ethernet fabrics.
This validation underscores QSAN’s capability to bridge high-speed NVMe performance with cost-effective networking, delivering scalable, future-ready storage infrastructure for next-generation workloads.
Seamless Virtualization with Proxmox Integration
StorageReview also confirmed rapid Proxmox VE integration with the XN4 Series via NVMe-oF (TCP). Through automated discovery and connection, NVMe namespaces instantly appear as LVM storage pools, enabling high-bandwidth, low-latency virtualization in minutes.
This validation reaffirms QSAN’s commitment to simplifying IT operations while maximizing virtualization performance.
