ABSTRACT:
A method and a mechanism are capable of partitioning computer hardware components or elements at the level of individual processing paths, or ropes. Incoming and outgoing queues may be designed such that transactions to/from one rope do not interfere with another rope. Each common queue is treated as a collection of virtual queues/buffers. Transaction generated by computer system components may include both the address and the partition identification (ID) of the component. This ensures that components of one partition cannot adversely affect components of another partition, or the entire computer system. The computer components include input/output (I/O) devices, such as ethernet cards, or other I/O devices. The method and mechanism may be adapted for use by computer components other than I/O devices.
