Product Info

RackStation RS18017xs+

Highly scalable NAS designed for virtualization, data-intensive applications and service continuity for large scale businesses

The Synology RackStation RS18017xs+ 12-Bay NAS Enclosure features four Gigabit Ethernet and two 10GbE ports as well as twelve storage bays, so you can provide a custom storage solution for network-connected users. The twelve bays support SATA and SAS interfaces on 2.5" SSDs along with 2.5" and 3.5" HDDs. Once user-supplied drives are installed into the bays, you can configure them in a RAID 0, 1, 5, 6, 10, JBOD, or Basic mode to preserve data and increase the drives' read and write speeds. Aside from storage capabilities, the RS18017xs+ leverages a 2.2 GHz Intel Xeon D-1531 six-core processor and 16GB of DDR4 ECC memory to quickly manage and deliver data.

The RackStation RS18017xs+ comes with an expansion port as well as two USB 3.0 ports for attaching optional storage expansion units, thumb drives, and other devices. For future upgrades, the RS18017xs+ can hold up to 128GB of RAM and additional 10GbE network interfaces cards installed in its two PCIe 3.0 x8 slots. To cool all the internal components, four onboard 80mm fans spin at various speeds to help dissipate the internal heat. In addition, the NAS features a 2 RU rack-mountable design and runs on two redundant 500W power supplies.
