Enterprise 12-bay rackmount NAS

The Synology SA3400 is a 2U rackmount network-attached storage system built around an Intel Xeon D-1541 8-core processor running at 2.1 GHz with turbo up to 2.7 GHz. It ships with 16 GB of DDR4 ECC memory expandable to 128 GB and provides twelve drive bays accepting 3.5" or 2.5" SAS and SATA drives. Connectivity includes two 10 GbE RJ-45 ports, four Gigabit RJ-45 ports and two USB 3.0 ports.

Suited for scalable file and backup workloads

This platform suits organisations needing high-throughput file serving, virtualization storage or large-scale surveillance recording with native capacity for up to 180 drives via expansion units. It is not for buyers who require pre-populated drives, who need a tower form factor, or who want a system with integrated graphics for transcoding workloads.

Verify rack space, power and drive compatibility

Confirm the 2U rack depth of 27.24 inches (28.50 inches with server ears) fits your cabinet and that the 100-240 V AC supply matches your PDU. Ensure you source 3.5" or 2.5" SAS or SATA drives separately, as the unit is diskless, and plan memory upgrades using DDR4 ECC RDIMM modules only.
