Abstract
A method and computer program product for improving or optimizing the configuration of expansion cards and expansion card slots in a computer system. The slot width of each slot is serially set to two or more link widths supported by the expansion card that is connect in each slot and each of the plurality of expansion cards is retrained at each of the set slot widths. The current link speed and a current link width for each of the plurality of expansion cards may be identified at each of the set slot widths to enable a determination of a configuration of the plurality of expansion cards within the plurality of expansion card slots that will improve collective throughput of the expansion cards. Optionally, the throughput of one expansion card may be prioritized over the throughput of another expansion card, such as those expansion cards or functionalities specified by user preferences or identified by system monitoring of loads placed on the expansion cards.
