Centralize data right on your desk
Meet the 12-bay desktop NAS that allows instant deployment with scalability up to 36 drives, delivering outstanding 2,358MB/s sequential throughput reading. DS3617xs is certified for VMware, Citrix, Hyper-V, and OpenStack, ready to bring superior agility and efficiency to businesses.
High-performance NAS server for RAM-intensive applications
Equipped with an Intel Xeon-D quad-core processor, DS3617xs delivers stunning performance with over 2,358 MB/s reading under a RAID 5 configuration with optional 10GbE and Link Aggregation enabled. Initially equipped with 16GB DDR4 ECC RAM (upgradable to 48GB), it ensures data accuracy when handling high-value data and mission-critical tasks.
Scale on demand
DS3617xs can be connected to one or two dedicated DX1215 expansion units, allowing you to expand storage capacity to up to 36 drives without disrupting service. The high-bandwidth cable ensures instant and lossless connections between the main server and the expansion units.
In addition to the four built-in Gigabit ports, DS3617xs comes with a PCIe 3.0 x8 slot to support an optional 10GbE Network Interface Card (NIC), maximizing bandwidth and meeting high performance requirements for data-intensive applications.
Reliable redundancy mechanisms
DS3617xs comes with comprehensive redundancy mechanisms to ensure business continuity. Built-in four LAN ports with failover provides reliable redundancy in the event of unexpected network failure. The high reliability system design, including fanless CPU heat-sink and passive cooling technologies, prevents a single point of failure.
5 year warranty
Synology DS3617xs is backed with Synology's 5-year limited warranty. With technical support and hardware replacement service, the 5-year warranty maximizes your enterprises' return on investment.
Synology Replacement Service (SRS)
The Synology Replacement Service (SRS)* provides free shipment of replacement units as early as the next business day. SRS can expedite the process of replacing defective products and minimize service downtime.
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, DS3617xs 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 DS3617xs allows IT administrators to fine tune access controls and set up privileges to files and folders on DS3617xs through the familiar Windows user interface. With compatibility for major protocols, DS3617xs 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, DS3617xs ensures information is stored with a high level of data integrity, while providing flexible and efficient data protection tools.
Seamless storage solution for virtualization environments
DS3617xs provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® & VAAI integration, DS3617xs 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
DS3617xs 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). DS3617xs 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
DS3617xs 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, DS3617xs 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. DS3617xs 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, DS3617xs also ensures redundancy in the event of unexpected network failure.
Secure your data
DS3617xs 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, DS3617xs provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention.
