Synology DiskStation DS1817+ features a quad-core processor with AES-NI hardware encryption engine, providing outstanding performance even with encryption. Supercharge your storage with the optional M.2 SSD adapter card for dual SSD cache drives. DS1817+ is the ideal storage solution for centralizing data backups, protecting critical assets, and sharing files across different platforms. Synology DS1817+ is backed with Synology’s 3-year limited warranty.

High Performance & Easy-to-Scale
Synology DS1817+ is a 8-bay network attached storage solution with great performance and scalability. DS1817+ is equipped with an Intel quad-core 2.4 GHz processor and 8GB memory, with the flexibility to expand up to 16GB for even more intensive workloads. With dual-channel memory design, it provides outstanding sequential throughput at over 1,179 MB/s reading and 542 MB/s writing under a RAID 5 configuration with 10GbE Link Aggregation is enabled.

DS1817+ supports up to 18 drives with two Synology DX517 Expansion Unit attached, allowing you to start small and easily to scale up on demand. The PCIe slot supports the optional PCIe M.2 SSD adapter card M2D17 for dual M.2 SATA SSD slots  to be used as SSD cache for greatly enhanced storage performance without using the 3.5" drive bays. The PCIe slot can also be used to upgrade the DS1817+ with 10GbE network add-in-cards.

Btrfs: Next Generation Storage
DS1817+ integrates the Btrfs file system, bringing the most advanced storage technologies to meet the management needs of modern large-scale businesses:

  • Flexible Shared Folder / User Quota System provides comprehensive quota control on all user accounts and shared folders.
  • Advanced snapshot technology with customizable backup schedule allows up to 1,024 copies of shared folder backups and 65,000 copies of system-wide snapshots without occupying huge storage capacity and system resources.
  • File or folder level data restoration brings huge convenience and saves time for users who wish to restore only a specific file or folder.
  • File self-healing: Btrfs file system is able to auto-detect corrupted files with mirrored metadata, and recover broken data using the supported RAID volumes, which include RAID 1, 5, 6, and 10.


Virtualization Ready
DS1817+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, Hyper-V, and OpenStack. With VMware vSphere 6 and VAAI integration certified, DS1817+ helps offload specific storage operations and optimizes computation power for unparalleled performance and efficiency in VMware environments. As the centralized storage of a virtual environment, DS1817+ enables virtual machine migration, allowing movement from server to server whilst eliminating service downtime and disruption to users. Windows Offloaded Data Transfer (ODX) and Synology Advanced LUN support greatly improves the efficiency on massive data transfer and migration. With OpenStack support, DS1817+ can be used as a block-based storage component for servers complying with the Cinder API. 

Robust Scalability
Management of the storage space on DS1817+ is simple and flexible. Multiple Volumes on RAID allows you to create more than one volume on a RAID structure, providing a flexible and efficient way to manage your storage across all available hard drives. When the need for more space arises, the volume can be easily expanded without any service disruption. DS1817+ provides the ability to seamlessly expand a single volume up to 108 TB on the fly. When the storage capacity of DS1817+ nears its limit, expansion is easily accomplished with up to two Synology Expansion Unit DX517 to support up to 18 SATA drives.

Reliability, Availability & Disaster Recovery
System reliability is of paramount importance to businesses which depend upon their commercial servers every day. DS1817+ responds to these concerns with wide-ranging availability and redundancy features:

  • Synology High Availability ensures seamless transition between clustered servers in the event of server failure with minimal impact on applications.
  • Snapshot Replication provides schedulable, near-instantaneous data protection, ensuring business documents in shared folders, virtual machines in iSCSI LUNs, or dockerized application data remain safe and available in the event of a disaster.
  • Redundant system fans and network ports with failover support ensure continual service uptime.
