5 Year Warranty

Synology's 5-year limited warranty provides hardware replacement and technical support via email and telephone services, maximizing your enterprises' return on investment.

Synology Replacement Services(SRS)

SRS provides free advance replacement units as early as the next business day in selected regions, maximizing the service uptime for your mission-critical storage and ensuring your business continuity.

RAID F1

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.

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.

Next-generation file system for better data protection

The Btrfs file system introduces advanced storage technologies and optimized snapshots to prevent data corruption and reduce maintenance overhead. While ensuring high-level data integrity, it also offers flexible, efficient data protection and recovery tools.

Flexible Shared Folder / User Quota System provides comprehensive quota control on 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 accelerates data recovery, providing more flexibility for businesses

 
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.

Snapshot Replication

Provides schedulable and instantaneous data protection for shared folders and virtual machines on iSCSI LUNs in the event of disaster.

Synology High Availability

Ensures seamless service transition between clustered servers in the event of a server failure.

Hyper Backup

Store multiple backup versions with block-level incremental data backup and cross-version deduplication.

CMS

Manage multiple Synology NAS servers simultaneously on a centralized interface to increase business efficiency.

Cloud Station Suite

Synchronize cross-platform data automatically with file version control on all your devices.

MailPlus

Secure, reliable, and private mail server solution with an intuitive and modern mail client.
