Abstract
A system and method for dynamic reconfiguration of at least one peripheral bus switch of a system includes a management controller that detects whether a server system is connected to each peripheral bus slot of the system. The management controller selects a peripheral bus switch topology for the at least one peripheral bus switch, based on the detecting. The management controller sets each port of the at least one peripheral bus switch to either an upstream port configuration or a downstream port configuration, based on the peripheral bus switch topology.
Claims18
A method, by a management controller, for dynamic reconfiguration of at least one peripheral bus switch of a system, comprising:
- detecting whether a server system is connected to each peripheral bus slot of the system;
- selecting a peripheral bus switch topology for the at least one peripheral bus switch, based on the detecting;
- and
- setting each port of the at least one peripheral bus switch to either an upstream port configuration or a downstream port configuration, based on the peripheral bus switch topology.
A system, comprising:
- at least one peripheral bus switch, each connected to a peripheral bus slot;
- a least one graphics processing unit connected to a downstream port of the at least one peripheral bus switch;
- and
- a management controller connected to the at least one peripheral bus switch, the management controller configured to:
- detect whether a server system is connected to each peripheral bus slot;
- select a peripheral bus switch topology for the at least one peripheral bus switch, based on the detecting;
- and
- set each port of the at least one peripheral bus switch to either an upstream port configuration or a downstream port configuration, based on the peripheral bus switch topology.
