Context Before

BlueField-4 will be the silicon anchor of this third network.

Evidence

Positioned on the storage array, it terminates NVMe-oF and RDMA traffic at line rate and manages KV movement independently of host CPUs and GPUs.

Context After

With 2×400G SerDes links providing 800Gb/s of bandwidth, integrated Grace CPU, and LPDDR, BlueField-4 would act as the controller for a distributed context memory fabric.

② Atomic Claim

部署在 storage array 上的 BlueField-4 會以 line rate 終結 NVMe-oF 與 RDMA traffic，並在不依賴 host CPUs、GPUs 的情況下管理 KV movement。
