Key Features
- Active-Active Dual Controllers: Its most significant feature is the dual-controller architecture, where both controllers remain active and work in parallel. This eliminates a single point of failure and ensures a seamless, sub-minute failover, providing non-disruptive service for mission-critical applications.
- Enterprise-Grade Hardware: Each controller is powered by a dedicated Intel Xeon D-1541 8-core processor and 8 GB of DDR4 ECC memory (for a total of 16 GB), providing the robust performance and data integrity needed for demanding workloads like virtualization and databases.
- SAS Storage & Scalability: The system supports dual-port SAS drives, a standard for enterprise storage. It offers 12 hot-swappable bays and can be expanded to a total of 36 drives by adding two Synology RXD1219sas expansion units.
- High-Bandwidth Networking: Each controller is equipped with a 10GbE port and two 1GbE ports. The system also includes PCIe expansion slots for optional 10GbE, 25GbE, or Fibre Channel (FC) host bus adapters, offering flexible, high-speed connectivity.
- Comprehensive Redundancy: The UC3400 is built with multiple layers of redundancy, including dual redundant power supplies and hot-swappable components, to ensure maximum uptime.
