A high-density 32x 400GbE QSFP-DD switch that is backward compatible with 100G QSFP28 modules. Break out each 400G QSFP-DD port into 4x 100GbE or 2x 200GbE to get up to 128 ports in a 1RU switch.
Equipped with built-in RoCEv2 capabilities, the switch offers advanced features such as PFC, ECN, and dynamic load balancing, enabling low-latency, lossless communication for RDMA-based AI workloads—without requiring additional investment in network infrastructure.
RoCE EasyDeploy simplifies lossless network deployment by automating PFC and ECN configuration, reducing manual effort and minimising errors to accelerate high-performance fabric rollout for AI and HPC workloads.
