SAN Synology UC3200 Rack 2U Intel Xeon D-1521 8GB DDR4 0TB

The Synology UC3200 is a 2U rack-mounted unified controller SAN engineered for reliable, highly available iSCSI services in small and medium business environments. Equipped with dual active-active controllers, an Intel® Xeon® D-1521 4-core processor (2.4 GHz, burst up to 2.7 GHz), support for up to 12 x 3.5"/2.5" HDD/SSD drives, and modular redundant components, the UC3200 is designed to deliver continuous block storage services with hardware-level security and flexible expansion options.

Advantages

Dual controller modules operate in active-active mode with automatic failover to maintain uninterrupted iSCSI services. The unit supports high-density SAS drives with up to 576 TB raw capacity, SED (Self Encrypting Drive) support for hardware-level data encryption, and a dedicated SATA DOM to isolate the operating system from user data. Hot-swappable 500W redundant power supplies and modular fans reduce service downtime. A PCIe 3.0 slot and onboard 10GbE plus 1GbE interfaces provide options to increase network throughput, while a Mini-SAS HD port enables easy volume expansion with Synology expansion units.

Suitable for

• iSCSI block storage for virtualization hosts (VMware, Hyper-V)
• Enterprise or SMB shared storage with high availability requirements
• Environments needing fast recovery and snapshot-based protection for VMs

How to use

Install the UC3200 in a standard 19" rack and populate drive bays with supported HDDs or SSDs. Connect network interfaces and, if required, install a 10GbE/25GbE NIC in the PCIe 3.0 slot to increase throughput. Use the DSM UC management portal to configure iSCSI LUNs, set up RAID groups, enable SED where supported, and configure networking (link aggregation, VLANs). For capacity expansion, connect compatible Synology expansion units to the Mini-SAS HD port. Configure Snapshot Replication and schedule snapshots to protect critical volumes and virtual machines.

Recommendations

For production deployments, use ECC memory and populate both controller modules according to Synology guidelines, deploy redundant power supplies and redundant network paths, and schedule regular snapshot and replication jobs. Test failover and recovery procedures in a controlled environment to ensure uninterrupted iSCSI service.
