Abstract
A system includes a central management agent and one or more field replaceable unit type specific management buses. Each field replaceable unit type specific management bus may couple the central management agent to a set of field replaceable units, with each unit in each set being the same type of field replaceable unit.
Claims30
A system comprising:
- a central management agent;
- and
- a field replaceable unit type specific management bus coupled to the central management agent.
A system comprising:
- a central management agent;
- a plurality of field replaceable units of a first type;
- a first management bus coupling the central management agent to only the first type of field replaceable unit;
- a plurality of field replaceable units of a second type;
- and
- a second management bus coupling the central management agent to only the second type of field replaceable unit.
3 more elements
A central management agent comprising:
- a system management circuit;
- a first management bus interface coupled to the system management circuit to communicate management information with only a first type of field replaceable unit;
- and
- a second management bus interface coupled to the system management circuit to communicate management information with only a second type of field replaceable unit.
1 more element
A system comprising:
- a chassis;
- a first plurality of interchangeable components located within said chassis;
- a second plurality of interchangeable components located within said chassis;
- a central management agent located within said chassis;
- a first management bus coupled to the central management agent and coupled to each of the first plurality of interchangeable components, wherein the first management bus is not coupled to any other components;
- and
- a second management bus coupled to the central management agent and coupled to each of the second plurality of interchangeable components, wherein the second management bus is not coupled to any other components.
4 more elements
A method of detecting a component failure in a computer system, the method comprising:
- detecting a failure indication at a central management agent for a first of a plurality of management buses;
- and
- determining that a type of field replaceable units has likely failed based on the identity of said first management bus.
A system comprising:
- a central management agent;
- a first set of components of a first type, wherein each of the components in said first set is interchangeable with the other components in said first set;
- a first management bus that is coupled to the central management agent and to the first set of components and that is dedicated to the first set of components;
- a second set of components of a second type, wherein each of the components in said second set is interchangeable with the other components in said second set but is not interchangeable with the components in said first set;
- and
- a second management bus that is coupled to the central management agent and to the second set of components and that is dedicated to the second set of components.
