Context Before

Secondly, the local NVMe storage for Rubin has been moved to a different location from that of NVMe storage in Grace Blackwell. Previously, local NVMe storage was managed by BlueField-3.

Evidence

For VR NVL72, the local NVMe storage is physically on the Orchid module managed by the ConnectX-9.

Context After

Lastly, the BlueField-4 DPU is able to control the 8 ConnectX-9 backend NICs allowing for unified management of both front end north-south network & back end high speed East-West networks. This system, known as Advanced Secure Trusted Resource Architecture (Astra), thus takes the provisioning and monitoring load off of the host CPU. The only issue with this is that BlueField-4 is expensive, so we expect most hyperscale customers to deploy their in-house DPU solutions instead.

② Atomic Claim

在 VR NVL72 中，local NVMe storage 實體位於 Orchid module 上，並由 ConnectX-9 管理。
