Fibre channel diagnostics in a storage enclosure
View Patent ↗A fiber channel analyzer for analyzing the operation of a fiber channel arbitrated loop (FC-AL) to which a plurality of devices are connectable is disclosed. The analyzer is adapted to be housed in an enclosure which, in use, houses at least one of the fiber channel devices. The analyzer extracts data from the fiber channel, processes the extracted data; and communicates processed data to a SES Processor through a secondary communication bus.
1. A fibre channel analyser for analysing the operation of a fibre channel arbitrated loop (FC-AL) to which a plurality of devices are connectable, said analyser being adapted to be housed in an enclosure which, in use, houses at least one of said devices and comprising:
means for extracting data from the fibre channel,
means for processing extracted data; and
means for communicating processed data to an environmental control and monitoring unit through a secondary communication bus
wherein the analyser is arranged to be located on one of a number of branches from the FC-AL and not in the loop itself.
2. The analyser of claim 1 wherein the analyser is adapted to analyse activity occurring on the loop but does not itself contribute to loop delay.
