Patent ID: 7568052

Claim:
A method of managing input/output (I/O) configurations for a group of logical partitions of a logical partition cluster of a computing environment, said method comprising: determining that said I/O configuration is to be adjusted, wherein said determining comprises using one or more workload goals in making the determination, and wherein the one or more workload goals are associated with workloads of a logical partition cluster, the logical partition cluster comprising a group of logical partitions residing on a common physical processor of said computing environment, the group of logical partitions of the logical partition cluster cooperatively sharing resources of the logical partition cluster and having workloads and resources managed by one or more cooperating workload managers, said determining comprising automatically consulting with the one or more cooperating workload managers of said logical partition cluster of the computing environment in making the determination, wherein said one or more workload goals comprise for a workload executing within the group of logical partitions of the logical partition cluster an expected completion time for the workload and an importance of the workload relative to another workload executing within the group of logical partitions of the logical partition cluster, and wherein the workload and the another workload are executing in one of the same logical partition or different logical partitions of the group of logical partitions of the logical partition cluster; selecting a channel path from a plurality of channel paths to be used in adjusting I/O configuration of the logical partition cluster of said computing environment, said selecting being based at least in part on an I/O velocity resulting from selecting the channel path; and dynamically adjusting said I/O configuration using the selected channel path, wherein said dynamically adjusting comprises dynamically connecting the selected channel path to a subsystem of said I/O configuration, said selected channel path and said subsystem being associated with the workload executing within the group of logical partitions of the logical partition cluster of said computing environment, and wherein the dynamically adjusting provides additional resources to said workload, wherein said selected channel path was removed from the another workload executing within the group of logical partitions of the logical partition cluster, thereby reducing resources of said another workload.
