Key Features

Superior Port Density with Exceptional Forwarding Performance

The WatchDog WD9865 delivers industry-leading port density with support for 400G, 200G, and 100G interfaces. With a peak forwarding capacity of up to 16 Tbps, the switch enables data centers to implement high-density server connectivity strategies while maintaining full non-blocking fabric performance across all port speeds and configurations.

Comprehensive Data Center Networking Capabilities

Modern data center deployments demand sophisticated networking features. This WD9865 Series portfolio includes: Advanced Overlay Networking: Full support for MP-BGP EVPN and VxLAN VTEP technologies, enabling flexible network virtualization and multi-tenant architectures. Low-Latency RDMA Support: Built-in ROCEv2 networking capabilities leveraging Priority-based Flow Control (PFC) and ECN Enhanced Transmission Selection (ETS) to guarantee minimal latency and lossless packet delivery for RDMA applications and high-performance computing workloads.

Programmable SDN Architecture

The WatchDog WD9865 integrates next-generation switching silicon that provides substantially greater flexibility for software-defined networking implementations. Enhanced OpenFlow table architecture, expanded ACL resources, and precision packet classification capabilities deliver dramatically improved SDN functionality compared to legacy platforms. This programmability fully addresses the requirements of enterprise SDN networks and controller-based fabric architectures.
