Award winning OS - DiskStation Manager

Synology DiskStation Manager (DSM) is a sleek, browser-based operating system running on every DiskStation and RackStation, which makes managing your Synology NAS a breeze. Featuring an intuitive user interface, DSM makes accessing and sharing your data smarter and simpler. Synology's Package Center lets you download and install useful add-on packages designed specifically for 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, DS216+ 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 DS216+ allows IT administrators to fine tune access controls and set up privileges to files and folders on DS216+ through the familiar Windows user interface. With compatibility for major protocols, DS216+ can eliminate server configuration overhead and enhance IT administrators’ efficiency.


Ultimate file center

File Station is a fast and secure feature for sharing and managing your files stored on DS216+. Just drag-n-drop and upload data from Mac or PC. Advanced filters make it easy to search for documents, photos, or videos. With built-in FTP or email clients, DS216+ lets you organize and share files through an advanced web application effortlessly. You can even share files and folders with others by simply sending a link. Files can be reached on mobile devices via the companion mobile app DS file. HTTPS, SSL/TLS encryption, and link expiry dates also ensure file sharing over the Internet is highly secure.


The most compatible sharing

Enjoy seamless files sharing across Windows®, Mac®, and Linux® platforms as DS216+ offers comprehensive network protocol support including FTP, SMB2, AFP, NFS and WebDAV. With Windows AD and LDAP integration, DS216+ can fit effortlessly into any existing network environment - there is no need for IT administrators to maintain two sets of credentials. You also won't worry about missing files with the Recycle Bin feature which is supported on AFP, CIFS, File Station, and WebDAV. All files deleted in a shared folder will be automatically moved into the Recycle Bin.

Effective backup solution

Synology DS216+ can serve as a centralized backup target. Whether you are a Windows or Mac user, you can back up everything on your computer directly to Synology NAS using Cloud Station. Whenever you modify a file, the changes are backed up to DS216+ automatically. Mac users also enjoy native Apple® Time Machine support. You can also back up data from your DS216+ to another DiskStation, rsync servers, external drives, or even Amazon® S3, Glacier cloud service, Microsoft Azure, SFR, and hicloud. "Backup & Replication" allows you to schedule backup tasks and restore the server to any particular point in time, while minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions.


All-in-one server

With just one DS216+, it's possible to handle a vast amount of tasks. DS216+ helps your company gain a competitive edge by acting as your multi-function server. Directory Server provides LDAP service, while DNS and DHCP packages allow you to host a domain name server and automate network IP assignment at no extra cost. With Synology's Proxy Server, you can regulate content access and monitor who can access which website while saving bandwidth. You can host up to 30 websites with Web Station, safeguard the office environments with Surveillance Station, send and receive mails using your own email domain with Mail Station, share printing capability with Printer Server, make DS216+ act as a VPN server to access company’s resources remotely, and more.


Increase business productivity with cloud solutions

With comprehensive cloud solutions, DS216+ 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.


Secure your data

DS216+ 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, DS216+ provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention.


Get mobility with our apps

Synology develops versatile mobile apps — DS note, DS audio, DS video, DS photo+, DS cloud, DS file, DS download and DS cam — allowing you to access and manage the contents of your DS216+ with smartphones and tablets. QuickConnect brings an easier network experience as it eliminates complicated router configuration or port forwarding. With Synology mobile apps, your multimedia collection and work files are always on the go.
