Dual-controller 12-bay SAS NAS

The Synology SA3200D is a 2U rackmount storage array with two active-passive controllers, each built around an Intel Xeon D-1521 4-core processor at 2.4 GHz with Turbo Boost to 2.7 GHz. It presents twelve 3.5"/2.5" SAS drive bays and ships with 8 GB DDR4 ECC UDIMM per controller, expandable to 64 GB. The platform runs DiskStation Manager and targets organisations that need continuous file, block and object services without a single point of failure.

Sustained multi-controller throughput

Under continuous load the active-passive pair maintains service while the standby controller mirrors state, enabling minute-level failover if the primary encounters a fault. Each controller provides a PCIe 3.0 x8 slot and an expansion port for additional SAS shelves, allowing raw capacity to scale beyond 500 TB with minimal performance impact. The architecture supports RAID F1, RAID 5 and RAID 6 for large volumes up to 200 TB when at least 32 GB RAM is installed.

Thermal and power envelope

The chassis operates from 0 °C to 35 °C with dual 100-240 V AC power supplies sharing the load across both controllers. Redundant cooling keeps internal temperatures stable during extended RAID rebuilds or iSCSI workloads, while the 2U form factor fits standard rack airflow without requiring specialised ducting. Power draw scales with the number of installed SAS drives and active expansion units.

Questions about this item

How much power does the SA3200D draw when both controllers run 24/7?

The unit accepts 100 V to 240 V AC at 50/60 Hz single phase; each controller uses an Intel Xeon D-1521 4-core 2.4 GHz processor with Turbo Boost up to 2.7 GHz and 8 GB DDR4 ECC UDIMM.

What drives and cabling must I supply to populate the 12 bays?

You need 12 SAS SSDs or HDDs in 3.5" or 2.5" form factor; drives are not included and the chassis provides 12 SAS drive slots.

Will the SA3200D share storage with my existing 1GbE and 10GbE switches?

Each controller has 2 x 1GbE RJ-45 and 1 x 10GbE RJ-45 (10GBASE-T) ports for direct connection to standard Ethernet switches.
