Patent number: 9875168Abstract: In an approach to automatic connection detection in an environment, the environment including a first device and a switching device, a first port on the first device being connected to a second port on the switching device, automatic connection detection occurs by associating a fifth port on the switching device to the second port. In response to detecting an identifier of a sixth port on a third device at the first port on the first device, it's determined that the sixth port on the third device is connected to the fifth port.Type: GrantFiled: August 21, 2015Date of Patent: January 23, 2018Assignee: International Business Machines CorporationInventors: Chang W. Chen, Jin Yan Huang

Patent number: 9229764Abstract: Responsive to a hypervisor determining that insufficient local resources are available for reservation to meet a performance parameter for at least one resource specified in a reservation request for a particular logical partition managed by the hypervisor in a host system, the hypervisor identifies another logical partition managed by the hypervisor in the host system that is assigned at the least one resource meeting the performance parameter specified in the reservation request. The hypervisor estimates a first cost of migrating the particular logical partition and a second cost of migrating the another logical partition to at least one other host system communicatively connected in a peer-to-peer network based on at least one previously recorded cost stored by the host system of migrating a previous logical partition to the at least one other host system.Type: GrantFiled: July 2, 2015Date of Patent: January 5, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Kevin J. Cawlfield, Chang W. Chen, Mitchell P. Harding, Michael C. Hollinger, Michael R. Reddock

Patent number: 8694996Abstract: A hypervisor negotiates to reserve at least one available local resource in a host system that meets a performance parameter for at least one resource specified in a reservation request by a particular logical partition from among one or more logical partitions of virtualized pools of resources managed by the hypervisor in the host system, wherein the at least one performance parameter is specified by a particular application initiating the reservation request. The hypervisor, responsive to determining that the at least one available resource is not available in the host system, negotiates for offers to migrate the particular logical partition to at least one other host system comprising at least one available remote resource that meets the performance parameter, wherein the at least one other host system is managed by at least one other hypervisor that manages one or more other logical partitions of virtualized pools of resources.Type: GrantFiled: July 18, 2012Date of Patent: April 8, 2014Assignee: International Business Machines CorporationInventors: Kevin J.
