Why E1
Software-defined architecture
Accelerate innovation and efficiency with easily programmable, software-defined silicon built for rapid development. Program with XDP, DPDK, SPDK. No proprietary SDK required. Arm System Ready.
On-path CPU fabric
The only DPU that doesn’t need a separate exception-handling slow path. On-path CPU fabric handles every packet.
Built to scale
Converge compute, storage, and networking to simplify and scale your infrastructure.
Key features
