摘要：
Automated techniques ensure that system central processing unit (“CPU”) power is not a bottleneck when migrating logical partitions from one system to another system or systems (e.g., in the event of a system evacuation). CPU resources needed to fully drive available bandwidth during the migration are computed. CPU resources of the system are then adjusted for the migration, which may comprise scaling down the CPU resources that are guaranteed for the executing partitions and/or adjusting relative partition variable weights to limit the amount of excess capacity that can be allocated to a partition.
