Scale storage and memory for growing data requirements
The Synology SA6400 is a 12-bay enterprise storage server designed for rapid expansion. Its 12-core AMD EPYC processor, 32 GB ECC memory, dual built-in 10GbE ports, out-of-band management and support for up to eight expansion units suit large data sets and demanding centralised storage environments.
Purpose-selected processor
AMD EPYC 7272 with 12 cores supports the model's verified business-storage positioning.
12 hot-swappable drive bays
Install compatible 3.5-inch sata hdd; 2.5-inch sata ssd and expand to 108 bays where the listed expansion unit is used.
Expandable ECC memory
The system includes 32 GB DDR4 ECC RDIMM and supports up to 1,024 GB (64 GB × 16).
Integrated business networking
4 × 1GbE RJ-45 plus 2 × 10GbE RJ-45 provides wired connectivity without requiring the main PCIe expansion option.
Storage and I/O expansion
The verified Mini-SAS HD expansion connection and 2 × Gen3 x8 slots (x8 link) support future capacity or connectivity requirements.
Redundant power supplies
Two power paths reduce exposure to a single power-supply failure.
Who is the Synology SA6400 best for?
A strong choice for
- Centralised business file storage and backup
- Growing data sets that need verified bay expansion
- Rack deployments using ECC memory and built-in 10GbE
- Multi-site file sharing and synchronisation
- IT teams that require hot-swappable drive support and managed expansion
Consider another model if you need
- A smaller system with fewer than 12 drive bays
- An active-active SAN architecture for dedicated block storage
- Dual-port SAS drive support
- A desktop enclosure rather than a rackmount system
