Product Overview Powerful storage solution
RS18017xs+ is built for flexible storage management with ultra-high performance at over 568,000 sequential read IOPS and 4,800 MB/s sequential read throughput1. DDR4 ECC RDIMM and 10GbE connectivity guarantees data accuracy and performance for mission-critical environment.

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.

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. Features Robust scalability and reliability
RS18017xs+ provides flexible storage scalability with the free combination of Synology Expansion Unit RX1217sas and RX2417sas2. Up to 7 Expansion Units can be connected, allowing business to start small and scale big.
