Synology RackStation RS4826xs+ 12-Bay 2U Rackmount NAS (Diskless, Intel Xeon D-1739, 16 GB ECC, 2x 10GbE)

The Synology RackStation RS4826xs+ is a high-performance 2U rackmount network-attached storage (NAS) server built for demanding enterprise and data-centre workloads. Powered by an 8-core Intel Xeon D-1739 processor and shipping with 16 GB of DDR4 ECC RDIMM memory, it combines reliable always-on operation with the throughput needed for virtualisation, surveillance, backup consolidation and large-scale file services.

Advantages

Twelve hot-swappable drive bays and dual built-in 10GbE ports deliver fast, resilient storage in a compact 2U chassis. Error-correcting memory, redundant power supplies and a five-year manufacturer warranty keep mission-critical data available, while DiskStation Manager (DSM) provides a mature, web-based platform for storage, backup and application management.

Suitable for

• Enterprise file servers and centralised storage consolidation
• Virtualisation back-ends (VMware, Hyper-V, Proxmox) and iSCSI targets
• Video surveillance recording and high-resolution media workflows
• Backup, archiving and disaster-recovery repositories

How to use

Mount the RS4826xs+ in a standard 19-inch rack, install 3.5" or 2.5" SATA drives in the hot-swap trays and complete initial setup through Synology DiskStation Manager. Create storage pools and volumes, configure the preferred RAID level, and connect the dual 10GbE ports to your switch for high-throughput access. Scale capacity later by attaching RX1225RP expansion units or adding M.2 NVMe cache and 25GbE network cards.

Recommendations

Populate the bays with enterprise-grade SATA drives and use a redundant RAID level (5, 6 or 10) for production data. Take advantage of the dual 10GbE links with link aggregation, and add an M.2 NVMe cache or 25GbE network card to remove bottlenecks in high-demand environments.
