In an arrangement comprising a partitioned computer system and a switch with multiple adapters, wherein adapters are combined to form channels on respective partitions, a method is provided for dynamically changing the configuration of channels to which some of the adapters are assigned. The method allows better utilization for over-all network bandwidth. In one embodiment, the method includes initially allocating the adapters to establish at least one communication channel between each partition and the switch, wherein one or more adapters are allocated to each channel. Metric data is acquired for each channel during a time period, wherein the metric data indicates bandwidth utilization of respective channels. The metric data is evaluated to detect a first channel that under-utilizes available bandwidth when a second channel is over-utilizing available bandwidth. Adapters are reallocated from the first channel to the second channel by leveraging advanced Operating System and firmware support for dynamic adapter configuration, following detection of such event.
