摘要： A method and system for communication in a system area network (SAN) data processing system are described. The SAN includes a plurality of interconnected nodes that each have at least one port for communication. To avoid communication-induced errors that may arise, for example, if multiple nodes share the same node ID, the port of a node in the SAN is marked as “fenced” to prevent transmission of packets of a first traffic type while permitting transmission of packets of a second traffic type. The marking of the port may be recorded, for example, in a configuration register of the port. While the port is fenced, only packets of other than the first traffic type are routed via the port. In one preferred embodiment, the second traffic type represents SAN configuration traffic, and the first traffic type represents non-configuration traffic. In this preferred embodiment, the marking of the port may be removed following communication of configuration traffic utilized to negotiate unique node ID throughout the SAN.

摘要： A clustered computer system, bridge device and method include support for an atomic ownership change operation that ensures orderly and reliable ownership management of an input/output (I/O) bridge device. A lock indicator is associated with a bridge device, and is used to indicate a “locked” or “unlocked” status of the bridge device. Whenever the lock indicator indicates that the bridge device is unlocked, an atomic operation such as a read request to a lock indicator register is utilized to both set the indicator to indicate a locked status for the bridge device, and to associate the bridge device with a source node that initiated the atomic operation. In connection with the lock indicator, write access to one or more configuration parameter registers is controlled such that only the node that is associated with the bridge device is permitted to update such configuration parameter registers.

摘要： A circuit arrangement, node, clustered computer system, and method incorporate a primitive communication mechanism for use in exchanging data between adjacent nodes coupled via a point-to-point network. A plurality of network ports are used to couple a node to other nodes in the clustered computer system over point-to-point network interconnects, and a plurality of communication registers are associated with each of the network ports for the purpose of storing data received through their associated network ports. A node desiring to communicate information to another node receives a port identifier from the other node that identifies the network port on the other node through which the pair of nodes are coupled. The port identifier is then used by the node to communicate data to the other node through the use of one or more write operations directed to the communication register on the other node that is associated with the network port identified by the port identifier. On the other node, a control circuit is used to automatically notify the other node whenever data is stored in any of its communication registers, e.g., by generating an interrupt in response to non-zero data being stored in any of such communication registers.
