Compute Tray Topology - Line hint:

Context Before
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.
Compute Tray Topology
Evidence
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.
