individual or business needs, meaning you can enjoy more
entertainment in your life or better productivity at work.
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
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. See
the white paper for more technical details regarding Btrfs and data
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
Seamless storage solution for virtualization
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
Synology CMS (Central Management System)

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
Ensuring business continuity & reliability
