Fit into business environments easily

With the support of Windows AD, LDAP, and Domain Trust, RS3617xs enables seamless account integration. The User Home feature can automatically create a "home" folder for every user account to minimize the administrator's effort in repeatedly creating "home" folders for all accounts. Windows ACL support on RS3617xs allows IT administrators to fine tune access controls and set up privileges to files and folders on RS3617xs through the familiar Windows user interface. With compatibility for major protocols, RS3617xs can eliminate server configuration overhead and enhance IT administrators’ efficiency.


Next-generation data protection and integrity

When dealing with large-scale data storage, businesses require a solution that offers reliable backup and prevents file corruption. With support for the next-generation Btrfs file system, RS3617xs ensures information is stored with a high level of data integrity, while providing flexible and efficient data protection tools.


Fast and efficient snapshots

Snapshots preserve the history of a shared folder allowing you to save up to 1024 backup copies for point-in-time recovery. Snapshots can be automatically captured up to every 5 minutes, without noticeably impacting system performance.


Metadata mirroring and survivability

Btrfs file system stores two copies of critical metadata on a volume, improving the availability and ensuring the integrity of your file system.


Corruption detection and correction

Btrfs generates checksums for data and metadata, and then verifies the checksums during each read process to ensure the integrity of the filesystem and files. If the file system discovers a mismatch, metadata will be repaired to keep file system consistent. In the meantime, corrupted files will be reported and logged.


Customizable quotas for shared folders

With Btrfs, you can specify a storage limit for each shared folder, making it possible to precisely control space consumption when multiple teams or departments save files on the same Synology NAS server.


Seamless storage solution for virtualization environments

RS3617xs provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® &VAAI integration, RS3617xs helps offload specific storage operations and optimizes computation power in VMware environments. Windows ODX support speeds up data manipulation as the data transfer is offloaded. iSCSI also lets SMB users consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks


Unified storage system

RS3617xs enables businesses to cost-effectively manage multi-protocol data by integrating file-level (NAS) and block-level (SAN) storage into one unified storage system. Files can be shared across Windows®, Mac®, and Linux® platforms seamlessly with comprehensive network protocol support (CIFS/SMB, AFP, and NFS). RS3617xs provides a cost-effective iSCSI solution, allowing large scale businesses to consolidate storage into data center storage arrays. With thin provisioning available for file-level iSCSI LUN, you can maximize storage utilization by oversubscribing provisions and grow storage space as needed.


Protection with LUN backup, snapshot, and clone

RS3617xs enhances the ease of moving and copying data in a virtualized environment with the features LUN Snapshot, clone, and replication. Synology’s LUN Clone and LUN Snapshot only consume 1/1000 of the original size highly optimizing storage usage. In addition, Synology's LUN Snapshot lets you create up 256 snapshots per LUN using point-in-time technology without having any impact on system performance. With better support to servers under VMware vSphere or Windows environment, IT managers can expect guaranteed VM status and data consistency through application-consistent snapshots


Synology CMS (Central Management System)

For enterprises with more than one Synology NAS server, CMS offers the flexibility and convenience for IT administrators to manage all of them from a single point of entry. Through a simple interface, you can obtain a clear overview on resource consumption and logs, helping you identify any issue right away. With group policies, CMS can do much more for your daily tasks. Once a NAS joins a group, it will automatically adopt its rules and behave as intended, without extra configuration


Increase business productivity with cloud solutions

With comprehensive cloud solutions, RS3617xs lets you create your own private cloud easily. Cloud Station is the perfect package to sync files across multiple devices. Files can be edited in offline mode and later synced to Cloud Station, which keeps up to 32 historical versions, allowing you to restore a file back to previous version or recover deleted files. With the mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprises, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can handpick individual folders that they want to sync to different devices, manually or automatically based on file format and size. Folders synced by Cloud Station can be encrypted on DSM — no one will be able to access its content without your private key.


Ensuring business continuity &reliability

Uninterrupted availability is a critical goal for all businesses. RS3617xs offers Synology High Availability (SHA) technology which combines an active and passive server into one cluster, the former always mirrored to the latter. Shared Folder Sync can replicate data in real-time to another Synology NAS at a remote location, giving your business the Recovery Time Objective (RTO) for prompt disaster recovery. With multiple LAN ports, RS3617xs also ensures redundancy in the event of unexpected network failure.


Secure your data

RS3617xs offers advanced security measures to protect you from potential security holes. Security Advisor analyzes system settings, password strength, network preferences and removes any possible malware. AppArmor blocks malicious programs from accessing unauthorized system resources. You can also customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered files. In addition, RS3617xs provides other security add-ons, such as AES encryption, 2-Step verification, IP block &allow list, Antivirus packages, firewall, and DoS attack prevention.
