Abstract
A method, system, and computer usable program product for energy conservation in multipath data communications are provided in the illustrative embodiments. A current utilization of each of several of I/O devices is determined. A violation determination is made whether an I/O device from the several I/O devices can be powered down without violating a rule. The I/O device is powered down responsive to the violation determination being false. A powering up determination may be made whether an additional I/O device is needed in a multipath I/O configuration. The I/O device may be located, powered up, and made available for multipath I/O configuration. A latency determination may be made whether a latency time of the I/O device can elapse before the time when the additional I/O device is needed. The powering on may occur no later than the latency time before the time the additional I/O device is needed.
