Synology RackStation RS3618xs 12-Bay 2U Rackmount NAS Server

Accelerate Your High-Density Corporate Storage Workloads With Powerful 12-Bay 2U Enterprise Rackmount Efficiency Engineered For Scalable Performance And Continuous Data Availability

High-Performance 2U Enterprise Storage Built For Heavy Workloads

The Synology RackStation RS3618xs is a reliable, high-speed 12-bay 2U rackmount NAS server designed specifically to satisfy the rigorous data management, virtualization, and centralized backup demands of large-scale enterprises. Powered by a quad-core Intel Xeon D-1521 processor running up to 2.7 GHz with hardware encryption and pre-installed with 8GB DDR4 ECC memory (expandable up to 64GB), this rackmount server delivers massive sequential read throughput exceeding 3,900 MB/s and over 143,500 iSCSI random read IOPS. Engineered to house 12 hot-swappable 3.5-inch or 2.5-inch SATA hard drives and solid-state drives, the RS3618xs provides an exceptionally strong data foundation for enterprise operations. Available now across Bangladesh, TechDistri brings you this genuine Synology enterprise solution backed by verified local warranties and expert technical support.

Dual PCIe Expansion Slots And Flexible Multi-Gigabit Networking

To ensure seamless integration with high-speed corporate network backbones, the RS3618xs comes equipped with four built-in Gigabit Ethernet RJ-45 ports supporting Link Aggregation and failover. For environments requiring ultra-high throughput or SSD cache acceleration, the chassis features dual PCIe 3.0 x8 slots. These expansion slots enable IT managers to install high-performance 10GbE, 25GbE, or 40GbE network interface cards, as well as M.2 NVMe SSD adapter cards to drastically increase IOPS and minimize latency during heavy multi-client access.

Massive On-Demand Scalability And Next-Generation DSM Btrfs Security

Designed to accommodate exponential enterprise data growth, the RS3618xs can scale up to 36 drive bays by connecting two Synology RX1217 or RX1217RP expansion units. Operating on Synology DiskStation Manager (DSM), the system leverages the Btrfs file system to deliver advanced data protection. Administrators benefit from automated file self-healing, fast point-in-time snapshots (up to 65,536 system-wide), and end-to-end volume encryption to shield core digital assets against ransomware threats. DSM also grants immediate access to an extensive application suite, including Active Backup Suite for centralized system backup, Synology Drive for cross-site private cloud file sync, and Surveillance Station supporting up to 75 IP cameras.

Full Virtualization Certification And Enterprise High Availability

The RS3618xs is fully certified for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack environments, delivering seamless virtual machine storage management. To eliminate unplanned downtime, two RS3618xs servers can be paired using Synology High Availability (SHA) to establish an active-passive server cluster with automatic minute-level failover. Backed by a 2-year limited manufacturer warranty, this 2U rackmount NAS serves as a reliable digital foundation for critical enterprise operations.
