High-capacity and scalable NAS to serve as a centralized backup destination or a file server for small- and medium-sized businesses
Scalable Storage Server On-Demand
RS2818RP+ is an ideal storage solution for small- and medium-sized businesses with great flexibility in terms of expandable storage capacity, upgradable memory and optional high-speed NIC support. It fits perfectly as a backup target for distributed businesses, a centralized file server, or a backup target for employee workstations in a growing business.
CPU - quad-core 2.1GHz RAM options - 4GB DDR4 UDIMM, up to 64GBNetwork - 4 x 1GbE port, optional 10GbE NIC supportChassis - 3U design, 16 SATA drive bays
Robust scalability and reliability
RS2818RP+ provides large, scalable storage capacity with affordable total cost of ownership. The 3U chassis design accommodates up to 16 drives and the storage capacity can be further scaled when connected to one Synology Expansion Unit RX1217 or RX1217RP1, providing a total drive count of 28 without disrupting host services.
Next-generation file system for better data protection
The Btrfs file system introduces advanced storage technologies and optimized snapshots to prevent data corruption and reduce maintenance overhead. While ensuring high-level data integrity, it also offers flexible, efficient data protection and recovery tools.
Flexible Shared Folder/User Quota System provides comprehensive quota control on all user accounts and shared folders
Snapshot Replication provides schedulable and storage capacity-saving data protection with 1,024 shared folder backups and 65,000 system-wide snapshots
File or folder level data restoration makes data recovery fast and flexible
Automatic file self-healing detects and recovers corrupted files without user intervention
Ultimate Backup Solution
RS2818RP+ 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.
Comprehensively backup your data to a local shared folder, an external device, another Synology NAS, an rsync server, or a public cloud to ensure data safety.
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.
Office 365 G Suite
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.
Digital asset protection
Powered by Synology DiskStation Manager (DSM), Synology NAS offers advanced security measures to protect against sudden data loss and potential security holes.
Analyzes system settings, password strength, network preferences, and removes any possible malware.
A kernel-level enhancement that blocks malicious programs from accessing unauthorized system resources.
AES 256-bit encryption
Encrypt shared folders and network data transmission to keep data from unauthorized access.
Prevent others from logging in to your DSM by generating a one-time password (OTP) on your mobile device.
Customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered package files.
Powered by Synology DSM
Award-winning operating system with an intuitive user interface and powerful capabilities.
Public Cloud Integration
Backup and synchronize data easily between your public cloud accounts and your NAS.
Ensures seamless service transition between clustered servers in the event of a server failure.
Comprehensive built-in security tools are constantly updated to tackle evolving threats and protect your devices.
Provides schedulable and instantaneous data protection for shared folders and virtual machines on iSCSI LUNs in the event of disaster.
Simplified backup solution for your Mac, PC, and mobile devices.
RS2818RP+ supports one Synology expansion unit RX1217/RX1217RP, sold separately.
