The CX732Q-N is a high-performance 400Gb Layer 3 switch purpose-built for Super Spine deployments in next-generation CLOS network architectures. Powered by the Marvell Teralynx 7 ASIC, it delivers up to 12.8 Tbps of non-blocking switching capacity with industry-leading latency of approximately 500 nanoseconds, making it ideal for AI clusters, hyperscale data centers, HPC environments and cloud infrastructures.
Running AsterNOS, Asterfusion's Enterprise SONiC-based network operating system, it supports advanced networking technologies including RoCEv2, VXLAN, BGP-EVPN, EVPN Multihoming, INT Telemetry and IPv6. Its high-performance forwarding engine and large packet buffer ensure outstanding throughput and deterministic performance under demanding east-west traffic patterns.
Designed for hyperscale networking, the CX732Q-N combines ultra-high bandwidth, ultra-low latency and open networking flexibility to build future-ready AI and cloud infrastructures.
