QSAN XF5 Series

The QSAN XF5 series (XF5226) is the flagship of QSAN's NVMe block storage line — extreme-performance NVMe with ultra-low 100µs latency on PCIe Gen4. Engineered for mission-critical Australian workloads such as real-time analytics, financial systems, and AI inference, the XF5 delivers tier-1 performance at price points that consistently land 40–50% below Pure Storage FlashArray and Dell PowerStore.

XEVO 3 brings mirrored firmware HA, complete RAID protection (0/1/3/5/6/10/30/50/60 plus N-way mirror plus RAID EE for fast rebuilds), QThin thin provisioning with space reclamation, QSnap snapshots up to 4096 per system, QReplica synchronous and asynchronous replication with traffic shaping. Dual-active SAN controllers with NTB-bus cache mirroring, ALUA, multipath I/O, zero-downtime firmware updates. New host-card options: 2x 32Gb FC SFP28 and 2x 25GbE SFP28 per slot.

QSAN's flash-management story is a structural differentiator: QSLife monitors SSD wear and predicts replacements before they become emergencies; QSRAID optimises endurance across the array. Both are native to XEVO 3 — no bolt-on third-party tooling required. The shared hardware platform with the [XN5 series](/vendors/qsan/products/xn5-series) unified array also gives Australian customers a future-proofing path: the chassis is the same; controllers can be swapped to add file protocols later.
