CX864E-N, Switch Ultra Ethernet IA 64×800Gb, Enterprise SONiC Ready

The CX864E-N is Asterfusion's flagship Ultra Ethernet switch, purpose-built for the next generation of AI, machine learning, HPC and cloud-scale infrastructures. Powered by the Marvell Teralynx 10 ASIC, it delivers an exceptional 51.2 Tbps switching capacity through 64 native 800Gb ports while supporting flexible breakout configurations down to 100Gb.

Running AsterNOS, Asterfusion's Enterprise SONiC-based network operating system, the CX864E-N combines open networking with advanced AI transport technologies including WCMP, INT-driven Routing, Packet Spray and extensive RoCE optimization. A large on-chip packet buffer exceeding 200 MB and hardware-assisted PTP synchronization with 10 ns accuracy ensure deterministic, high-performance networking for the most demanding AI clusters.

Designed for hyperscale AI infrastructures, the CX864E-N provides vendor-independent interoperability with heterogeneous GPU clusters and SmartNICs while delivering the performance and flexibility required by next-generation Ultra Ethernet Consortium (UEC) architectures.
