Abstract: 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 nullfencednull 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.

Abstract: An address translation manager creates a set of chained tables that may be allocated in non-contiguous physical memory, and that may be dynamically resized as needed. The chained tables comprise one or more tables that each correspond to a logical partition, with each table including a pointer to a table corresponding to a virtual connection in the logical partition. The chained tables are managed by the address translation manager, which uses the system memory manager to dynamically allocate and free memory for a chained table as needed.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment dynamically allocate and/or deallocate data structures on demand to respective partitions in a logically-partitioned electronic device. The data structures are associated with an adapter, and the partitions may use the data structures to access the adapter and, in an embodiment, to send and/or receive messages across a network.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment pre-register buffers remotely and create tokens locally that represent the buffers prior to a data transfer operation that uses the tokens to access the buffers. In an embodiment, the buffers are pre-registered via a translation table, and the tokens are used as an offset into the translation table. In an embodiment, the pre-registration verifies that the buffer is within memory allocated to a logical partition, which protects against the risk of address corruption.
