QSAN XN3 Series — Dual-Active NVMe Unified Storage
The Synology graduation point — dual-active NVMe at SMB pricing.
The QSAN XN3 series is the smallest dual-active NVMe unified storage product on the market in 2026, and for Australian SMBs that's the headline. Where the older XCubeNAS 3000 line caps out at single-controller towers, and the broader Synology RS / QNAP TVS family ship single-controller (or active-passive cluster pairs at best), the XN3212 brings genuine active-active controllers, mirrored firmware, and 99.9999% high availability into a 12-bay 2.5"/3.5" mixed NVMe-ready chassis priced for small business.
Running QSM 4 — QSAN's 128-bit ZFS-based unified operating system — the XN3 delivers the full enterprise data-services suite on a small chassis. Snapshots, replication, deduplication, compression, WORM, SED at folder/pool/drive level, XMirror multi-site sync, public-cloud backup to Amazon S3 / S3-compatible targets, and public-cloud sync to Google Drive / OneDrive / Dropbox. Block (iSCSI) and file (CIFS, NFS, AFP, FTP, WebDAV) on the same array — true unified storage rather than a NAS with iSCSI bolted on.
For Australian SMBs and mid-market organisations who have outgrown Synology's single-controller architecture but cannot justify NetApp / Pure / Dell pricing, the XN3 is the structural answer. The shared chassis platform with the [XF3 series](/vendors/qsan/products/xf3-series) block array also gives partners a clean upgrade path: start a customer on XF3 block, swap controllers later for XN3 when file protocols become a requirement.

In Australia the XN3 lands directly opposite Synology UC-series (cluster-pair active-passive HA, not true active-active) and QNAP TES-series (active-active but with QNAP's security track record baggage). Dell PowerVault ME5 and Pure Storage land at roughly twice the price for similar dual-active NVMe. NetApp does not play in this size band. The structural difference: XN3 is the smallest genuinely active-active NVMe unified product on the market, and it ships with QSM 4 cross-platform replication that lets the array act as a DR target for QSAN block arrays — a tiering and DR story competitors can't match between their own product lines.
One of the advantages of working with CRS — we can recommend the best combination of vendors for your specific needs.
NAKIVO
NAKIVO backs up VMs running on XN3 iSCSI block targets and protects file shares with agentless snapshot integration.
Keepit
Keepit handles SaaS data in the cloud while the XN3 manages on-premises unified storage — clean separation of concerns.
Proxmox
Proxmox VE clusters connect to XN3 via iSCSI for VM storage and NFS for ISO / template libraries — true unified.
StoneFly
Replicate XN3 snapshots to StoneFly air-gapped immutable DR targets for ransomware protection.
