Abstract:
1. In a computing network having at least two data storage or processing devices, a method performed by a computer system for providing a complete end-to-end data path verification in the computer system, the computer system comprising at least a first physical data path and a second physical data path from a processor of the computer system to a data receiver of the computer system, the method comprising: providing a data initiator within the computer system, the data initiator comprising the processor, wherein the processor is coupled to the first and second physical data paths, and wherein the first and second physical data paths within the computer system are configured to be coupled to the at least two data storage or processing devices in the computing network and external to the computer system; transmitting a predetermined data test pattern from the processor to the data receiver of the computer system over the first physical data path, wherein the first physical data path is within the computer system; requesting from the data receiver the transmitted predetermined data test pattern that the data receiver received from the data initiator; reading the received data test pattern from the data receiver over the second physical data path, wherein the second physical path is within the computer system; and comparing the predetermined data test pattern transmitted to the data receiver over the first physical data path with the data test pattern read from the data receiver over the second physical data path.
