Synology SA3400D - Rackmount Network Attached Storage server

The Synology SA3400D is a 2U rackmount NAS server designed for high-availability environments. It features 12 hot-swap drive bays for SAS drives, supporting both 2.5-inch and 3.5-inch HDDs and SSDs. The unit is powered by an 8-core, 16-thread Intel Xeon D-1541 processor, with a base clock speed of 2.1 GHz that reaches 2.7 GHz under load. Dual controllers and redundant 500 W power supplies ensure service continuity in the event of hardware failure.

Network connectivity is provided by three RJ45 LAN ports supporting speeds up to 10 Gbit/s. The system includes 8 GB of ECC DDR4 memory, which detects and corrects single-bit errors to prevent data corruption. Total memory is expandable to 64 GB to accommodate demanding workloads or virtualisation. Storage is managed via the Synology DiskStation Manager, a web-based administration interface. Supported file systems include Btrfs and ext4, providing features for snapshots and metadata integrity. Two 60 mm fans provide cooling, and the system has a typical power consumption of 257.78 W. Access and security are managed through ACL permissions, with support for protocols such as LDAP and SNMP.
