NAS Synology UC3400 Rack 2U Intel Xeon D-1541 8GB DDR4

The Synology UC3400 Rack 2U with Intel Xeon D-1541 and 8GB DDR4 is an enterprise-class SAN appliance designed for high availability and mission-critical workloads. The system supports Fibre Channel (FC) and iSCSI protocols, offers active-active dual controllers with non-transparent bridge (NTB) for inter-domain communication, and delivers high sustained performance suitable for virtualization and large-scale block storage deployments.

Advantages

UC3400 provides zero-downtime protection through active-active dual controllers and NTB, delivers over 180,000 4K random write IOPS for demanding workloads, and includes certifications and integration with VMware, Microsoft Hyper-V, Citrix XenServer and OpenStack. It also supports Windows ODX, VMware VAAI, ALUA, snapshot-based protection, self-encrypting drives, flexible networking options up to 10/25 GbE and 16 Gb Fibre Channel HBAs, and capacity expansion with Synology RXD1219sas units.

Suitable for

• Enterprise SAN for virtualization platforms (VMware, Hyper-V, Citrix)
• Database and high IOPS workloads requiring low latency
• Block-storage back-end for OpenStack Cinder
• Environments needing continuous availability and data protection

How to use

Install the UC3400 into a standard 19-inch rack (2U height) and connect power and network interfaces according to your chosen topology. Configure storage pools, LUNs and networking through Synology’s management interface, enable required integrations (VMware, Hyper-V, OpenStack) and install optional network cards or Fibre Channel HBAs on each controller if needed. Add Synology RXD1219sas expansion units to increase raw capacity up to supported limits and populate drive bays with supported HDDs or SSDs following Synology guidelines.

Recommendations

For production environments, deploy UC3400 with redundant power and network paths, use enterprise-grade drives certified for Synology systems, enable snapshot and encryption features for data protection, and test controller failover and array integration with your virtualization platform during commissioning.
