Synology UC3200 12-Bay Unified Controller SAN Enclosure

The Synology UC3200 is a 12-bay SAN enclosure created for organizations that refuse to accept downtime. Its chassis houses two active controllers that run at the same time; if one ever stops, the second continues serving data so applications stay online.

The unit starts with 12 SAS drive bays that provide up to 192 TB of raw space when filled with 16 TB drives. When projects grow, you can attach up to two RXD1219sas expansion units and reach 576 TB without migrating data or changing your storage platform. This gradual growth model suits fast-moving businesses, video teams with expanding media libraries, or any virtualized environment that outgrows capacity in predictable steps.

Each controller relies on a quad-core Intel Xeon D-1521 processor and 16 GB of ECC DDR4 memory. Memory can be expanded to 128 GB, which helps the array maintain consistent latency during demanding workloads such as virtual desktop sessions or high-transaction databases. ECC protection guards against memory errors that could otherwise corrupt data.

Networking flexibility is built in. Every controller offers four 1 GbE ports and two 10 GbE ports, and link aggregation lets you combine them for higher throughput or failover. Two PCIe 3.0 slots accept additional network adapters or Fibre Channel cards whenever specialised connectivity is required.

Data protection features go beyond redundant hardware. Snapshot Replication lets you keep up to 4 096 point-in-time copies across the system, enabling rapid recovery after accidental deletions or ransomware attacks. Hardware-based AES-NI encryption secures data at rest with minimal performance impact, and self-encrypting drives are also supported to meet strict compliance rules.

The array integrates cleanly with VMware, Hyper-V, OpenStack and Windows ODX, so administrators can provision iSCSI or Fibre Channel storage to multiple hypervisors from a single interface. Day-to-day management is handled through Synology’s familiar browser-based software, making tasks like volume creation, firmware updates and performance monitoring straightforward.

A five-year warranty that includes hardware replacement and expert technical support rounds out the package, giving IT teams long-term confidence in their storage investment.
