Abstract
In one aspect of the present description, in an input/output (I/O) device having multiple CPUs and multiple I/O ports, a cycle of I/O port rotations is initiated in which each port rotation of the cycle includes rotating an assignment of at least one I/O port from one CPU to a different CPU of a plurality of the CPUs. In the illustrated embodiment, an I/O port assignment for each CPU of the plurality CPUs is rotated for at least a portion of the cycle. Other features and aspects may be realized, depending upon the particular application.
