The RS2418RP+ comes with four 1GbE RJ-45 ports, which can be bonded with Link Aggregation to enable automatic network failover and load balancing.Two RS2418RP+ units can be paired using Synology High Availability to form a reliable active-passive server cluster, maximizing service uptime.The RS2418RP+ also features redundant and hot-swappable power supply units to protect service continuity in case there are issues with one power source.
Room for expansionEasily adjust the 2U 12-bay RS2418RP+ to match the usage of your environment, whether it needs performance, faster networking, or higher storage capacity.Storage expansionAdd 12 extra drive bays for a total of 24 drive bays with a RX1217RP expansion unit.SSD cacheBoost read/write IOPS for HDD arrays with NVMe or SATA SSD cache.Flexible networking optionsImprove I/O or add redundancy with 10GbE SFP+ or RJ-45 networking.Versatile storage for businessesThe RS2418RP+ is ideal for small to medium-sized businesses and branch offices seeking a high-performing, reliable, and cost-efficient storage solution for file management, data backup, and surveillance.Intuitive storage for on-site and remote teamsMulti-endpoint data protectionSmart and scalable surveillanceIntuitive storage for on-site and remote teamsProvide secure and convenient cross-platform file access, sharing, and synchronization across multiple locations.
Private file cloudEnable efficient collaboration with Synology DriveSynology Drive provides remote data access, synchronization, on-demand file restoration, and backup via handy desktop and mobile applications.Learn moreMulti-platform supportAccess personal and shared data from mobile apps, desktop clients, web browsers, or another Synology system. Any changes you make are automatically synced to other devices as soon as they are connected.Collaborate in real timeEnable concurrent editing of documents, spreadsheets, and slides with Synology Office, with support for conversion to and from Microsoft Word, Excel, PowerPoint, and OpenDocument files.Learn more
Efficient multi-site synchronizationConnect teams with Hybrid ShareUse Hybrid Share to store large sets of data in the cloud, leveraging the large bandwidth of our data centers to stream requested files to local NAS deployed at the branch offices.Learn moreReliable data access on demandWith Hybrid Share-enabled folders, remote teams retain full access to the most up-to-date files while benefiting from a reduced local storage footprint and lower bandwidth usage.Local caching of most-used dataFrequently-accessed files are kept on the local NAS, allowing users to access them at LAN speeds. Files and folders can also be pinned manually to prevent them from being replaced when the cache is full.
Multi-endpoint data protectionDesign an effective backup strategy to maximize data and system availability with a host of native and license-free solutions.
Consolidated backup serverEndpoint, VM, and NAS/SAN protectionSecurely back up Windows, Mac, and Linux endpoints, Synology servers, and VMware® and Hyper-V® virtual machines with Active Backup for Business.Learn moreMicrosoft 365 and Google WorkspaceCentralize backups of Microsoft 365 and Google Workspace data to protect cloud data from accidents and simplify compliance with data retention policies. Schedulable backups, flexible file versioning, and block-level deduplication ensure flexibility and savings in terms of storage and bandwidth consumption.Learn more
Data protection and recoveryHyper BackupBack up files, LUNs, installed applications, and system configurations to destinations including Synology C2 Storage, public cloud platforms, USB devices, file servers, local folders, and other Synology systems.
Set and forget backup tasks with regular schedules, enhance security with granular user permissions and encryption, keep backup sizes small with built-in deduplication, and restore data flexibly with multi-versioning.
Snapshot ReplicationSnapshot Replication enables configurable point-in-time snapshots of shared folders and VM storage with an RPO as low as 5 minutes and recovery within seconds.Learn more
Smart and scalable surveillanceLeverage flexible deployment options, intuitive management capabilities, and advanced video analytics to secure your premises.
Simple-to-deploy local surveillanceWide device compatibilityConnect up to 40 IP cameras from a selection of over 8,600 validated models thanks to Synology Surveillance Station’s wide camera compatibility.Multi-platform convenienceMonitor live streams or watch recordings from web browsers, desktop clients, or the DS cam mobile app.Secure and private storageFootage is stored locally for easier compliance with data protection regulations and further protected from unauthorized access with industry-standard AES-256 encryption.
Flexible monitoring of multiple locationsAssisted camera deploymentAutomatically locate new cameras within a set IP range, and configure units in batch via spreadsheet import or replicating settings to new cameras.Centralized management and monitoringStay on top of your deployment by previewing triggered events directly on multi-floor or multi-location maps, with online map integration for Google Maps and OpenStreetMap.Time-saving video analyticsTake advantage of intelligent monitoring features such as motion detection, no-idle zones, foreign object detection, and anomaly detection that cater to common surveillance scenarios.

Notes: Model specifications are subject to change without prior notice. The figures are based on Synology internal testing. Each performance test is done individually. No other services or applications are processed at the same time. The actual performance may be lower than lab testing figure due to differences in server configuration, deployment, and the number of active operations. If usage requirements exceed the specifications above, please contact our regional partners for professional advice.
