Astonishing Performance

Powered by an Intel Xeon D-1541 eight-core processor and 16GB DDR4 ECC RDIMM (up to 128GB), Synology FS2017 delivers over 90K 4K Random Write IOPS1 , making it ideal for video post-production, mail server, virtualization and database solutions, which require low-latency and ultra-high performance.

FS2017 comes with dual 10GBase-T ports and supports optional 10GbE / 25GbE / 40GbE network interface cards, allowing flexible, high-performance network configurations.

Cost Effective Unified Storage

Synology FS2017 is compatible with major SAS / SATA SSD brands to avoid vendor lock-in. FS2017 is also a unified storage server supporting iSCSI protocol and file sharing services, which provides the cost savings and simplicity of consolidating storage over an existing network while providing the flexibility required by virtual server environments. In addition to the internal 24 drive bays, FS2017 supports up to two Synology RX2417sas expansion units to provide a total of 72 2.5" drive bays for scalability.

Virtualization Ready

FS2017 provides seamless storage solutions for virtualization environments, including VMware, Citrix, Hyper-V, and OpenStack. With VMware vSphere 6 and VAAI integration certified, FS2017 helps offload specific storage operations and optimizes computing power for unparalleled performance and efficiency in VMware environments. Windows Offloaded Data Transfer (ODX) and Synology Advanced LUN support greatly improves the efficiency on massive data transfer and migration. With OpenStack support, FS2017 can be used as a block-based storage component for servers complying with the Cinder API.

Rock-Solid Data Protection

The Snapshot Replication application provides schedulable, near-instantaneous data protection. It replicates 65,000 system-wide backup copies to offsite servers and local volumes, bringing near-instantaneous data protection and ensuring data in shared folders or virtual machines in iSCSI LUNs remain available in the event of a disaster.

With block-level incremental backup and cross-version deduplication, Synology Hyper Backup provides multi-version backup with optimized storage space utilization and allows multiple backup destinations to local shared folders, external hard drives, network shared folders, rsync server, and public cloud services.

Comprehensive Business Applications

Powered by the innovative Synology DiskStation Manager (DSM), FS2017 comes fully-equipped with applications and features designed specifically for large-scale business:

  • Windows AD and LDAP support allowing easy integration with existing business directory services without recreating user accounts.
  • Windows ACL support provides fine-grained access control and efficient privilege settings, allowing FS3017 to fit seamlessly into current infrastructure.
  • MailPlus allows your business to set up a secure, reliable, and private mail server while giving your employees a modern mail client for receiving and sending messages.

Reliability and System Availability

System reliability is of paramount importance to businesses which depend upon their commercial servers every day. FS2017 responds to these concerns with wide-ranging availability and redundancy features:

  • Synology High Availability ensures seamless transition between clustered servers in the event of one node failing with minimal impact to applications.
  • Redundant power supplies, system fans, and multiple network ports with failover support ensure maximum continuous service uptime.
  • DDR4 ECC RDIMM detects and corrects errors during data transmission.
  • The tool-free system fan design allows hot swapping and simple exchanging of malfunctioned system fans. Optional Synology RKS1317 rail kit provides fast and easy system installation and maintenance.


Faster performance, greater scalability, and easier management

Synology FlashStation FS2017 is a high performance 24-bay rackmount NAS designed for 2.5" SSDs. FS2017 brings easy to manage, lightning-fast storage, perfect for video post-productions, mail servers, virtualization environments, and database applications.


Due to the peculiarities of SSD and RAID technology, a common challenge lies in how to prevent all of the drives from failing at the same time because of the evenly distributed workload. RAID F1 alleviates this problem with a specially designed algorithm to unevenly distribute workload to drives, enhancing the resilience of the storage pool and ensuring your data remains safe.

Compared with traditional RAID, RAID F1 distributes uneven workload to SSDs to prevent all drives from wearing out simultaneously.

Fast and reliable networking

Fast and reliable networking

With the multi-LAN design, FS2017 is capable of performing Link Aggregation and failover. For environments requiring a higher speed, an optional Ethernet add-on card can be installed into the PCIe slot, providing fast data transmission of 40GbE/25GbE/10GbE.

Btrfs: Next generation storage efficiency

Btrfs file system introduces 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
  • Snapshot Replication provides schedulable and storage capacity-saving data protection with 1,024 shared folder backups and 65,000 system-wide snapshots
  • File or folder level data restoration makes data recovery fast and flexible
  • Automatic file self-healing detects and recovers corrupted files without user intervention

Fully certified storage virtualization solutions

Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with easy management interface. VMware vSphere 6 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate. OpenStack Cinder support turns your Synology NAS into a block-based storage component.
