Patent number: 10915481Abstract: An approach is provided in which an information handling system detects a reduced capacity on a PCIe link that interfaces a host system to a PCIe I/O expansion drawer over a first/second physical cable. The information handling system verifies a first/second connection to a first/second connector on the PCIe I/O expansion drawer, receives a first/second set of vital product data over the first/second physical cable, and determines that the first physical cable and the second physical cable are connected to the same PCIe I/O expansion drawer based on analyzing the first/second set of vital product data. The information handling system then suspends operation of one or more components corresponding to the PCIe link and trains the PCIe link to an increased capacity. In turn, the information handling system resumes operation of the one or more components and restores the PCIe link to the increased capacity.Type: GrantFiled: April 18, 2019Date of Patent: February 9, 2021Assignee: International Business Machines CorporationInventors: Curtis S. Eide, Christopher J. Engel, Aditya Saripalli

Patent number: 10664040Abstract: A method utilizes event-driven reoptimization to reallocate one or more logical partitions within a pool of logically-partitioned data processing systems in a logically-partitioned computing environment in response to detection of a system event that is likely to increase or decrease the collective resource demands of logical partitions resident in a logically-partitioned computing environment. The reoptimization may be used to consolidate logical partitions on fewer processor nodes to improve the potential for powering down hardware resources and thereby reduce power consumption.Type: GrantFiled: November 27, 2017Date of Patent: May 26, 2020Assignee: International Business Machines CorporationInventors: Curtis S.

Patent number: 10108575Abstract: An approach is provided in which a host system receives a request to power down a selected I/O module located in a PCIe I/O expansion drawer. The host system identifies at least one cable card located in the host system that corresponds to the selected I/O module and transmits at least one set of sideband signals to the PCIe I/O expansion drawer through at least one set of PCIe cable links. The host system, in turn, inhibits the transmission of the at least one set of sideband signals to power down the selected I/O module.Type: GrantFiled: April 14, 2016Date of Patent: October 23, 2018Assignee: International Business Machines CorporationInventors: Curtis S.
