Two FX2421 expansion units extend the system to 72 drives for organisations building high-performance virtualisation, database or media-production storage. Twenty-four flash bays Deploy compatible 2.5-inch SAS HDDs, SAS SSDs or SATA SSDs in a hot-swappable 2U system. Dual Xeon processors Two Intel Xeon Silver 4110 processors provide 8 cores and 16 threads per CPU. Large ECC memory capacity Start with 32 GB DDR4 ECC RDIMM and expand to 512 GB across 16 slots. Built-in dual 10GbE Two 10GbE and two 1GbE ports provide fast connectivity without consuming PCIe slots. Scale to 72 drives Connect two identical FX2421 expansion units to increase the verified drive count. Resilient rack hardware Redundant power and replaceable system fans support service-continuity planning. Who is the Synology FS6400 best for? A strong choice for All-flash virtualisation storage Database and transaction workloads Media post-production teams Large flash-based file services Organisations needing up to 72 drives Consider another model if you need You require a compact desktop NAS Your workload does not justify a 2U all-flash platform You need more than 72 drives You need a newer platform generation for a greenfield deployment Key specifications Model FS6400 Product type 24-bay 2U all-flash storage server Processors 2 × Intel Xeon Silver 4110 CPU frequency 2.1 GHz base / 3.0 GHz turbo System memory 32 GB DDR4 ECC RDIMM Maximum memory 512 GB (32 GB × 16) Drive bays 24; up to 72 with FX2421 × 2 Drive types 2.5-inch SAS HDD/SSD or SATA SSD Built-in network 2 × 10GbE and 2 × 1GbE PCIe expansion 2 × Gen3 x8 slots (x8 link) Dimensions 88 × 482 × 724 mm Warranty 5 years Full technical specifications Processor and memory CPU model Intel Xeon Silver 4110 CPU quantity 2 CPU cores 8 per processor CPU threads 16 per processor CPU architecture 64-bit CPU frequency 2.1 GHz base / 3.0 GHz turbo Hardware encryption engine Supported System memory 32 GB DDR4 ECC RDIMM Pre-installed memory 32 GB (16 GB × 2) Total memory slots 16 Maximum memory 512 GB (32 GB × 16) Memory guidance Use identical Synology modules and follow the exact-model manual Storage, network and expansion Drive bays 24 Maximum drive bays 72 (FX2421 × 2) Drive categories 2.5-inch SAS HDD, 2.5-inch SAS SSD or 2.5-inch SATA SSD Hot-swappable drives Supported RJ-45 1GbE ports 2 RJ-45 10GbE ports 2 USB ports 2 × USB 3.2 Gen 1 Expansion ports 1 × Mini-SAS HD PCIe expansion 2 × Gen3 x8 slots (x8 link) Expansion guidance FX2421 expansion units must be used as an identical pair Drive compatibility Confirm exact drives on Synology’s FS6400 compatibility list Physical design and power Form factor 2U Size (H × W × D) 88 × 482 × 724 mm Weight 17.26 kg Rack support 4-post 19-inch rack; RKS-02 sold separately System fans 80 × 80 mm × 4 Fan modes Full-speed, cool and quiet Replaceable system fans Supported Noise level 53.7 dB(A) Power recovery Supported Scheduled power on/off Supported Wake on LAN/WAN Supported Power supply 800 W Redundant power Supported AC input 100 V to 240 V AC Power consumption 288.49 W access; 145.8 W HDD hibernation Thermal output 984.37 BTU/hr access; 497.49 BTU/hr HDD hibernation Environment, warranty and package Operating temperature 0°C to 35°C Storage temperature -20°C to 60°C Operating humidity 8% to 80% RH Storage humidity 5% to 95% RH Certifications FCC, CE, BSMI, VCCI, RCM, UKCA, EAC, CCC, KC, BIS Environment RoHS compliant Warranty 5 years Package contents Main unit × 1; accessory pack × 1; AC power cord × 2; quick installation guide × 1 Rail kit RKS-02 sold separately Frequently asked questions about the Synology FS6400 What is the Synology FS6400?The Synology FS6400 is a 24-bay 2U all-flash storage server for I/O-intensive and latency-sensitive business workloads.Which processors are in the FS6400?It uses two Intel Xeon Silver 4110 processors, each specified with 8 cores, 16 threads and a 2.1 GHz base / 3.0 GHz turbo frequency.How much memory does the FS6400 include?It includes 32 GB DDR4 ECC RDIMM and supports up to 512 GB across 16 memory slots.How many drive bays does the FS6400 have?The FS6400 has 24 hot-swappable bays and expands to 72 drives with two identical FX2421 units.Which drive categories does the FS6400 support?Synology lists 2.5-inch SAS HDDs, SAS SSDs and SATA SSDs.
