US Patent 7248592 Partitionable data fabric and computing arrangement

A circuit arrangement and method for interfacing a node and a data fabric. In a computing arrangement that includes a plurality of nodes intercoupled by the data fabric, each node is assigned to one of a plurality of partitions. A node-interface circuit is configured to interface with the source node, and a translation circuit translates data between a first format compatible with the nodes and a second format compatible with the data fabric. An access control circuit either enables or disables transmission of data from the source node based on whether the source and destination nodes are in the same partition.
