High-speed scalable storage server
Synology RS3618xs is a reliable, superior-performance network-attached storage solution for large-scale enterprises with demanding business applications. It simplifies data management, optimizes virtualization environments, and rapidly expands storage capacity with minimal time investment in setup and maintenance.
Ready for 10GbE and beyond
PCIe 3.0 slots allow for faster networking options as you expand your infrastructure. Together with the built-in quad Gigabit ports, RS3618xs offers comprehensive connectivity options for link aggregation and failover configurations.
Ultimate Backup Solution
RS3618xs integrates various backup applications to safeguard your important data on any device with an intuitive user interface and durable storage technologies.
Active Backup for Server
An agentless backup solution protects data from Windows and Linux servers through SMB and Rsync to minimize deployment and management costs.
Hyper Backup
Comprehensively back up your data to a local shared folder, an external device, another Synology NAS, an rsync server, or a public cloud to ensure data safety.
Desktop Backup
Safeguard your PC with Cloud Station Backup. Effortlessly back up data stored on macOS to Synology NAS with Time Machine.
Active Backup for Office 365/ G Suite
On-premise backup solution with a centralized dashboard. Optimize storage efficiency with single instancing and block-level deduplication technology.
Fully certified storage virtualization solutions
Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with easy management interface. VMware vSphere 6 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate. OpenStack Cinder support turns your Synology NAS into a block-based storage component.
Next-generation file system for better data protection
