XCubeNXT 5100 Hybrid Unified Storage
Unify data management — flash speed meets HDD capacity.
The XCubeNXT 5100 series is the hybrid cousin of the NVMe model, and for many organisations it's the sweet spot: you get unified block-and-file storage with intelligent tiering between flash and spinning disk. It's built for businesses that need performance where it matters and capacity where it's affordable — without managing two separate arrays.
Running on QSM 4 (the same ZFS-based operating system as the NVMe variant), the 5100 series delivers enterprise features like Hybrid SSD Cache, automatic data tiering, deduplication, and compression. The active-active dual-controller architecture ensures zero downtime during upgrades and intelligent failover — your apps keep running even when you're doing maintenance. QSM 4 also brings cross-platform replication: a 5100 unified pool can act as a DR target for an XEVO 3 block array on the same network, which is a tiering and DR story very few competitors can match between their own product lines.
This is the go-to box for enterprise data consolidation, hybrid cloud deployments, cross-platform file sharing, and backup repositories. It competes with NetApp FAS and the top-end Synology/QNAP enterprise units, but unlike those platforms, QSAN brings true active-active dual controllers and enterprise-grade ZFS data integrity to the mid-market. No more choosing between reliability and budget.

The XCubeNXT 5100 hybrid goes head-to-head with NetApp FAS, and honestly, with enterprise Synology and QNAP units that are increasingly being pushed into business environments. Here's the difference: Synology and QNAP use active-passive or single controllers — fine for a home lab, risky for production workloads. NetApp FAS is brilliant but priced for the top end. QSAN's XCubeNXT brings true active-active HA dual controllers with enterprise-grade ZFS data integrity to the mid-market. For Australian organisations that've outgrown their Synology but can't justify NetApp pricing, the XCubeNXT hybrid is the logical step up.

Branded drives and renewals are where a tier-one storage array actually costs you. A look at how QSAN structures it differently, and what that changes.
VSAN vs SAN: Which is Best for You?
SAN and vSAN solve the same problem — shared storage for your virtual machines — in very different ways. Here is how to tell which one fits your environment.
