QSAN

QSAN Technology delivers a full enterprise storage portfolio across five product categories: SAN (XCubeSAN hybrid flash), Unified NAS (XCubeNAS and XCubeNXT), All-Flash NVMe block storage (XCubeFAS, plus the new XF3, XF4 and XF5 series), Dual-Active NVMe Unified Storage (the new XN3, XN4 and XN5 series — launched May 2026), and Container Servers (the new KS1 and KS2 line, running KSM). Every line is engineered around true active-active controllers and pricing that lands well below Dell, NetApp, HPE and Pure Storage for the same architecture. The SAS/SATA hybrid lines add third-party drive support (Seagate, WD, Toshiba); the NVMe all-flash configurations run QSAN-branded NVMe drives, qualified for performance, reliability and platform compatibility.

The XF3, XF4 and XF5 flash arrays run XEVO 3 with mirrored firmware HA, PCIe Gen4 NVMe acceleration, and headline random-write performance of 50,000 IOPS at 100µs (100,000 IOPS at 200µs) on the XF5 flagship — competitive against Pure FlashArray and Dell PowerStore at materially lower TCO. The XN3, XN4 and XN5 unified series share hardware platforms with their XF siblings (XF32 ↔ XN32, XF42 ↔ XN42, XF52 ↔ XN52) and run QSM 4 for combined block plus file protocols. QSM 4 introduces cross-platform replication, the first time QSAN's unified and block environments can replicate to each other natively — a clean tiering and DR story most competitors don't offer between their own products.

The KS1 and KS2 container servers run the new KSM operating system, providing on-premises Kubernetes infrastructure as a converged compute and storage appliance. Up to 8-node clustering with GUI-driven deployment, no CLI required for daily operations. Designed for Australian customers who need on-prem container hosting for data sovereignty, edge computing, or to avoid Broadcom-VMware licensing on Tanzu. The XE5 NVMe JBOF (XE5026) is QSAN's first NVMe-oF JBOF, purpose-built for AI training and disaggregated infrastructure with server-direct connectivity.

QSAN's XInsight management plane unifies QSM 4, XEVO 3 and KSM under a single console, with two new sub-products: QSeal air-gapped backup for data security — available on the QSM platform only (the XN unified series), not on XEVO block-only arrays — and QComposer for compute orchestration. XCubeSAN remains the workhorse hybrid SAN line with single-to-dual controller upgrade paths, third-party drive support, and 99.9999% availability — the platform that put QSAN on the Australian channel map. XCubeDAS expansion now scales to a 78-bay XD5378 chassis for capacity-intensive deployments.
