QSAN Unified Storage
XN5226S-12C

Performance-Oriented All NVMe Unified
Storage for Demanding Workload

Presenting Lightning-Fast Performance for Enterprises

QSAN XN5 series is the premier enterprise-level all-NVMe flash unified storage solution with unparalleled speed. With μs-level latency, it meets the responsiveness needs of the most challenging enterprise applications. The XN5 is ideal for modern applications, including AI model training, real-time databases, HPC (HighPerformance Computing), and media production.

Accelerate Your Business with 100 µs Latency

The XN5 series features an NVMe SSD architecture designed to ensure consistent response times, prioritizing steady performance instead of occasional peak throughput. Tailored for enterprise high-performance computing infrastructures, it delivers high IOPS with latency at the microsecond level. With minimal latency concerns, applications are shielded from slowdowns or halts caused by high response times. Matching with the RDMA technology, XN5 can mostly eliminate the latency when accessing data from the host to the drive.

Always-on for Business

XN5 is equipped with mirrored firmware architecture, built-in hot-swappable, and fully redundant hardware design, streamlining maintenance and upgrades. Its dual active controllers operate, and online firmware upgrades deliver seamless storage services in real-time, guaranteeing uninterrupted service delivery with zero downtime.

Sweatless Management Experience

QSM continuously evolves security levels to protect data across storage and adhere to industry best practices. Supporting SED (Self-Encrypting Drives) coupled with WORM (Write Once Read Many) will keep your sensitive data safe even if the drives are lost, stolen, or misplaced. Additionally, Windows ACL (Access Control List) and RBAC (Role-Based Access Control) help to prevent unauthorized access to your data.

Reduce Business Overhead through Data Reduction

Equipped with advanced data reduction capabilities, including deduplication and compression, the XN5 offers unparalleled efficiency, allowing businesses to significantly reduce overhead costs.
