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.

Award winning OS

Fit into business environments easily

With the support of Windows AD, LDAP, and Domain Trust, DS3615xs 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 DS3615xs allows IT administrators to fine tune access controls and set up privileges to files and folders on DS3615xs through the familiar Windows user interface. With compatibility for major protocols, DS3615xs can eliminate server configuration overhead and enhance IT administrators’ efficiency.

Fit into business environments easily

Seamless storage solution for virtualization environments

DS3615xs provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® 5 & VAAI integration, DS3615xs 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.

Seamless storage solution

Unified storage system

DS3615xs 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). DS3615xs 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.

Unified Storage System

Protection by LUN backup, snapshot, and clone

DS3615xs enhances the ease of moving and copying data in a virtualized environment with the features - LUN Backup, LUN Snapshot, and LUN Clone. DS3615xs offers iSCSI LUN backup at storage level without extra charge. Synology LUN Clone and LUN Snapshot only take up 1/1000 of the original size which highly optimizes 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.

Protection

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.

Synology CMS

Increase business productivity with cloud solutions

With comprehensive cloud solutions, DS3615xs 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.

Increase Business Productivity with Cloud solutions

Ensuring business continuity & reliability

Uninterrupted availability is a critical goal for all businesses. DS3615xs 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, DS3615xs also ensures redundancy in the event of unexpected network failure.

Ensuring business continuity and reliability

Secure your data

DS3615xs 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, DS3615xs provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention.
