Product Overview

SYNOLOGY 24 BAY NAS FLASHSTATION FS6400

Expert Overview

The Synology FS6400 is a 2U rackmount NAS FlashStation designed for high-performance, all-flash storage deployments in business environments. It features dual Intel Xeon Silver 4110 8-core CPUs, 32 GB of DDR4 ECC RDIMM memory (expandable to 512 GB), and 24 drive bays compatible with 2.5" SAS HDD, SAS SSD, and SATA SSDs. This diskless unit provides a foundation for organizations requiring rapid data access and low-latency operations, such as virtual machine storage, high-transaction databases, or demanding multimedia workflows. With a maximum internal raw capacity of 184.32 TB and support for expansion units up to 552.96 TB, it addresses significant storage needs. Connectivity includes two 1GbE and two 10GbE LAN ports, along with two PCIe Gen3 x8 slots for additional network interface cards, ensuring robust data transfer capabilities. Redundant power supplies and hot-swappable drives contribute to system uptime.
