Synology RackStation
RS4017xs+


Powerful storage solution
RS4017xs+ provides rock-solid storage solution with ultra-high performance at over 690,000 sequential read IOPS and 4,900 MB/s sequential read throughput1. DDR4 ECC UDIMM and 10GbE connectivity guarantees data accuracy and performance for mission-critical environment.

Robust scalability and reliability
Storage capacity of RS4017xs+ can be further scaled up when connected to two Synology Expansion Unit RX1217 or RX1217RP2, providing a total drive number of 40 without disrupting host services.

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.
