Abstract
Methods, systems, and apparatus are disclosed for throttling a point-to-point, serial I/O expansion subsystem within a computing system that include: receiving, by a link configuration module, an external environmental parameter value representing a condition of an environment external to the computing system; determining, by the link configuration module, a link configuration of a communication link for an I/O adapter in a point-to-point, serial I/O expansion subsystem within the computing system in dependence upon the external environmental parameter value; and configuring, by the link configuration module, the communication link for the I/O adapter in dependence upon the link configuration.
