Managing a subsystem of an information handling system by a data processing unit (DPU)

An information handling system comprising a processor having access to memory media storing instructions executable by the processor to perform operations, comprising:

• identifying a first connection between a DPU and a switch;
• identifying a second connection between the switch and a subsystem;
• identifying computational capabilities of the DPU, including routing support of the DPU;
• determining, based on the identified computational capabilities of the DPU, that the DPU supports multi-directional link subdivision;
• in response to determining that the DPU supports multi-directional link subdivision:
• configuring the DPU to select the multi-directional link subdivision as an operating mode of the DPU;
• configuring the switch to invoke a virtual switch hierarchy at the switch to enable communication between the DPU and the subsystem through the virtual switch hierarchy;
• and
• after configuring the DPU and the switch, accessing, by the DPU, the subsystem to manage operation of the subsystem.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• identifying a first connection between a DPU and a switch;
• identifying a second connection between the switch and a subsystem;
• identifying computational capabilities of the DPU, including routing support of the DPU;
• determining, based on the identified computational capabilities of the DPU, that the DPU supports multi-directional link subdivision;
• in response to determining that the DPU supports multi-directional link subdivision:
• configuring the DPU to select the multi-directional link subdivision as an operating mode of the DPU;
• configuring the switch to invoke a virtual switch hierarchy at the switch to enable communication between the DPU and the subsystem through the virtual switch hierarchy;
• and
• after configuring the DPU and the switch, accessing, by the DPU, the subsystem to manage operation of the subsystem.
