12-bay active-passive dual-controller SAS storage
Synology SA3200D 12-Bay Dual-Controller High-Availability Storage Server
The Synology SA3200D is designed for high-availability file services and centralised business storage, combining Intel Xeon D-1521, 8 GB DDR4 ECC UDIMM per controller, 12 hot-swappable bays and 2 × 1GbE plus 1 × 10GbE RJ-45 per controller.
- Processor

- Networking
- 2 × 1GbE plus 1 × 10GbE RJ-45 per controller
Shared storage with automatic controller failover
The Synology SA3200D uses two active-passive controller modules to reduce service interruption in a 2U shared-storage design. It provides twelve dual-port SAS bays, 8 GB ECC memory per controller, built-in 10GbE and expansion to 36 drives.
Active-passive controller protection
A secondary controller can take over services when the active controller is unavailable.
12 hot-swappable drive bays
Install compatible 3.5-inch dual-port sas hdd; 2.5-inch dual-port sas hdd/ssd and expand to 36 bays where the listed expansion unit is used.
Expandable ECC memory
The system includes 8 GB DDR4 ECC UDIMM per controller and supports up to 64 GB (16 GB × 4) per controller.
Integrated business networking
2 × 1GbE plus 1 × 10GbE RJ-45 per controller provides wired connectivity without requiring the main PCIe expansion option.
Storage and I/O expansion
The verified Mini-SAS HD expansion connection and 1 × Gen3 x8 slot (x8 link) per controller support future capacity or connectivity requirements.
Redundant power supplies
Two power paths reduce exposure to a single power-supply failure.
Who is the Synology SA3200D best for?
A strong choice for
- Business file and block storage where service continuity matters
- Backup repositories and centralised data management
- Organisations wanting active-passive controller failover in one chassis
- SAS deployments expanding from 12 to 36 drive bays
- Rack environments requiring redundant power and built-in 10GbE
Consider another model if you need
- A smaller system with fewer than 12 drive bays
- An active-active SAN architecture for dedicated block storage
- A SATA-only drive strategy without SAS media
- A desktop enclosure rather than a rackmount system
