Context Before
Datacenter Secure Control Module (DC-SCM)
Evidence
These modules provide management security functions over the compute tray. Hyperscalers usually have their own in-house management module design. Therefore, the management modules may be different for each end customer. Besides BlueField-4, the power delivery module and the management modules are the only other two components within the compute tray that Nvidia allows customization for. Some end customers are considering integrating the management modules into the power delivery module. Nevertheless, the modules need to follow the form factor that Nvidia provides so it can fit into the designated connector on the compute tray midplane.
Context After
Compute Tray Topology
The compute tray topology of VR NVL72 is roughly similar to that of GB200 and GB300. The three main differences to Grace Blackwell are the connections between GPU and ConnectX NICs, the connections to the local NVMe storage, and the connection between the BlueField-4 and ConnectX-9.
② Atomic Claim
不過，這些 modules 仍必須遵循 Nvidia 提供的 form factor，才能裝入 compute tray midplane 上指定的 connector。
