Synology RackStation 16-bay (up to 40-bay); Octa Core 2.1 GHz; 16GB DDR4 ECC UDIMM RAM (up to 64GB); 4x GbE LAN; 2x10GbE LAN; 2x USB3.2
This is a Synology RS4021xs+, a 16-bay 2U rackmount NAS from Synology's enterprise xs+ line, expandable up to 40 total drives — a serious storage backbone for organisations running large file shares, backup infrastructure, surveillance footage archives, or virtualization datastores. It's built around an Intel Xeon D-1541 octa-core processor at 2.1GHz, a genuine server-grade CPU (not a repurposed consumer chip) that comfortably handles the parity calculations, encryption, and simultaneous client load an enterprise NAS needs to sustain.
It ships with 16GB of DDR4 ECC UDIMM memory and scales up to 64GB, with ECC protection catching silent memory corruption before it can propagate into stored data — an important distinction from consumer NAS units. Storage scales from the 16 internal bays out to 40 drives total via expansion units, giving substantial headroom to grow capacity over the unit's lifetime without a forklift upgrade. Networking is built for throughput: 4x Gigabit Ethernet plus 2x dedicated 10GbE ports for link aggregation or segregated backup/client traffic, alongside 2x USB 3.2 ports for direct-attached expansion or UPS signalling. Runs Synology's DSM operating system with full support for Snapshot Replication, Btrfs self-healing file systems, and High Availability clustering — the same enterprise software stack shared across Synology's whole xs+ rackmount range, so administrators moving between units in this family don't need to relearn a different management interface.
