Synology UC3400
The Synology UC3400 is a 2U, 12-bay dual-controller SAN designed for mission-critical, high-performance environments. With active-active controllers based on Intel Xeon D-1541 CPUs and ECC memory, it delivers over 180,000 4K random write IOPS (up to ~455K mixed IOPS over Fibre Channel), ensuring uninterrupted block storage via iSCSI or Fibre Channel. Fully virtualisation-ready, it supports VMware, Hyper-V, OpenStack Cinder, and comes with enterprise tools like Snapshot Replication, self-encrypting drive support, and high availability failover. The system includes hot-swappable power supplies, up to 576 TB expansion via RXD1219sas units, and flexible networking from built-in 10GbE/1GbE ports to optional 25GbE or Fibre Channel add-ons. Backed by Synology’s DiskStation Manager and a five-year warranty, the UC3400 brings pro-grade NAS scalability and resilience with minimal downtime.
Reliability and & Availability
Active-active dual controllers work simultaneously to ensure zero downtime in the event of a controller failure while the non-transparent bridge (NTB) enables inter-domain communication to maximize the protection of in-flight data.
Active-Active SAN
Designed for mission-critical environments, UC3400 is a high-availability SAN solution supporting Fibre Channel (FC) and iSCSI protocols. With over 180,000 4K random write IOPS,1 it supports a wide range of demanding workloads.
Virtualisation Ready
Support for Windows Offloaded Data Transfer (ODX), VMware vSphere Storage APIs Array Integration (VAAI), and ALUA ensure optimized and efficient storage operations, and the unit is full certified for VMware, vSphere, Micr. OpenStack® Cinder support enables the UC3400 to become a block-based storage component as well.
Flexible Network Options
Boost network from 10GbE and dual 1GbE RJ-45 ports to 10/25 Gb Ethernet cards or 16 Gb Fibre channel host bus adapters on each controller.
Data Protection & Security
Maximize service uptime for critical services and enhance data security with snapshot protection and self-encrypting drive support in UC3400. Built-in software offers application-aware snapshot protection and instant recovery of virtual machines in iSCSI LUNs in the event of a disaster. In terms of SEDs, the unit natively supports it, providing hardware-level encryption for mission-critical and sensitive data at rest.
