Patent ID: 7254652

Claim:
A method for autonomic configuration of port speeds of components in a computing environment, the method comprising: reading a cable identifier of an interconnection cable connecting the components in the computing environment, wherein the cable identifier contains the length of the interconnection cable; storing the cable identifier of the interconnection cable in a software object within the computing environment; and autonomically adjusting the port speeds of the components connected by the interconnection cable based on the identifier, comprising steps of: determining the maximum port speeds of each of the components connected by the interconnection cable; translating the cable length of the interconnection cable to a maximum effective transmission speed for the interconnection cable; if the maximum port speed of any of the components connected to the interconnection cable is less than the maximum effective transmission speed of the interconnection cable, adjusting the port speed of each of the components to the lowest maximum port speed of the components; and if the maximum port speed of each of the components connected to the interconnection cable is greater than or equal to the maximum effective transmission speed of the interconnection cable, adjusting the port speed of each of the components to the maximum effective transmission speed of the interconnection cable.
