XN5 Series XN5226
Performance-Oriented All-NVMe Unified Storage (2U / 26 bays)
The XN5 series is a premier enterprise-level all-NVMe flash unified storage solution delivering μs-level latency and high IOPS—ideal for AI model training, real-time databases, HPC, and media production. Its NVMe SSD architecture prioritizes consistent response times over peak bursts and, combined with RDMA, can largely eliminate host-to-drive latency.
QSAN XN5226
Applications
Enterprise reliability with mirrored firmware architecture, dual-active controller option, non-disruptive upgrades, cache-to-flash protection, and modular hardware for effortless management.
