QSAN XCubeNAS 5100R

The QSAN XCubeNAS 5100R series is the capacity-optimised, cost-effective sibling to the [8100R](/vendors/qsan/products/xcubenas-8100r). Same QSM 4 software stack, same multi-layer security, same multi-PB scalability via XCubeDAS — but with optional 10GbE host-card networking instead of built-in quad 10GbE SFP+, giving Australian SMBs and remote offices a lower entry price for capacity-intensive workloads.

The compact chassis generates a small carbon footprint and remains versatile for storage and expansion across general-purpose deployments. Hybrid SSD cache accelerates I/O when needed; the underlying chassis is media-inline ready for capacity-driven file workloads. Multi-protocol QSM 4 (AFP, CIFS, FTP, iSCSI, NFS, WebDAV) plus Windows AD / LDAP / ACL plus the built-in security stack (WORM at folder level, pool encryption, SED at folder/pool/drive) deliver enterprise-grade controls at SMB pricing.

For Australian customers building backup repositories, departmental file servers, or low-I/O archive targets where the 8100R's built-in 10GbE is over-provisioned, the 5100R is the right answer. For higher-throughput workloads, step up to the 8100R or move to a dual-active unified array like the [XN3 series](/vendors/qsan/products/xn3-series).
