Synology RackStation RS3618xs 12-Bay NAS Server

Synology RackStation RS3618xs Overview

Well-suited for large-scale enterprises with demanding business applications, the RackStation RS3618xs 12-Bay NAS Server from Synology helps simplify data management, optimizes virtualization environments, and rapidly expands storage capacities. This unit has 12 drive bays, each of which natively supports 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs. Should users need to expand the overall capacity of their RS3618xs, the optional RX1217/RX1217RP expansion units offer an additional 12 drive bays, and two of these units are supported via an integrated expansion ports.

The RackStation RS3618xs is powered by a 2.4 GHz Intel Xeon D-1521 Quad-Core processor, which will allow you to run multiple functions simultaneously. The built-in 8GB of DDR4 ECC RAM will allow quick access to frequently used files and programs and may also be upgraded to a total of 64GB by installing four 16GB modules into the available memory slots. Also featured are two USB 3.0 Type-A ports, which allow it to be connected to your Windows or Mac system. Network connectivity is achieved via the four Gigabit Ethernet ports with failover support, which help to provide redundancy in the case that a LAN connection malfunction occurs on one port. In addition, link aggregation, powered by four LAN ports, helps to increase connection speeds beyond the limits of a single network port or cable. If you're looking to expand this NAS, there are two PCIe Gen 3.0 x8/x8 slots that support a 10GBE NIC and more.

The RackStation RS3618xs runs on the DiskStation Manager (DSM) operating system, which helps simplify managing your NAS, as well as accessing and sharing data. A variety of RAID modes are supported, which help provide users with data redundancy, speed, or a combination of both. Supported RAID modes include RAID 0, 1, 5, 6, 10, Basic, and Synology Hybrid RAID. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.

Synology has engineered the RackStation RS3618xs to be energy efficient. Not only does it offer four 80 x 80mm fans to help keep the system running cool, the server supports numerous scheduled power on / off cycles and hard drive hibernation to further minimize power consumption and operation expenses. The RackStation RS3618xs operates on 100-240 VAC at 50/60 Hz and includes an accessory pack and an AC power cords. Protection is provided by a limited 5-year hardware warranty.
