A system and method for fault containment and error handling within a domain in a partitioned computer system includes a system manager having read and write access to a resource definition table. The system manager is adapted to quiesce the system when failure occurs within a domain, identify an allocated resource associated with the failed domain, identify a non-failed domain, and exit the quiesce mode for the non-failed domain, thereby containing a failure within the failed domain. The system manager further handles an error within the failed domain by deallocating a resource allocated to the failed domain so that the resource becomes available to non-failed domains.

Fault containment and error handling in a partitioned system with shared resources

A mechanism for balancing message traffic in a multi-chassis fully interconnected computer system partitioned into multiple domains allows the system to identify I/O transactions, to route I/O transactions over inter-domain cables, and to route non-I/O transactions over intra-domain cables. This beneficially reduces message traffic congestion on intra-domain cables.

Routing mechanism for static load balancing in a partitioned computer system with a fully connected network

A domain partitioning system for a multi-node computer system is disclosed. An external server manager is coupled to a domain configuration unit by a dedicated sideband channel. The server manager has write privileges to the domain configuration unit that allows the server manager to control the domain partitioning and the routing tables. None of the domains of the computer system are permitted write access to the domain configuration unit. In one embodiment, the domain configuration unit is a set of domain partition registers and routing table registers coupled to a system interconnect.
