32x400G and 2x10G ultra-low latency cloud switch with hot-swappable PSU and fans, front-to-rear airflow. Designed for leaf/spine deployments with Enterprise SONiC pre-installed for open, high-throughput automation.
DCS-O3202KE is a compact 1RU ultra-low latency cloud switch equipped with 32 x 400G QSFP-DD and 2 x 10G SFP+ uplinks, delivering up to 12.8 Tbps of full wire-speed L2/L3 switching. Powered by Marvell Teralynx ASIC, the platform is optimized for high-performance spine/leaf deployments in AI/ML clusters, distributed storage, and cloud-scale networks.
With support for RoCEv2, QCN, DCQCN, and in-band telemetry (INT), it delivers true lossless Ethernet and real-time visibility. Running SeraNOS, a SONiC-based containerized OS, it enables full-stack automation via REST API, Ansible, Python, and integrates with the Sera Fabric Controller (SFC) for SDN-driven operations.
