Abstract: A method utilizes priority-based bandwidth allocation to reallocate unused bandwidth capacity of a virtualized IO resource such as a self-virtualizing IO resource to one or more virtual functions in an allocation pool based upon priorities assigned to such virtual functions.

Abstract: An apparatus and program product utilize priority-based bandwidth allocation to reallocate unused bandwidth capacity of a virtualized IO resource such as a self-virtualizing IO resource to one or more virtual functions in an allocation pool based upon priorities assigned to such virtual functions.

Abstract: A method, system and computer program product are provided for implementing dynamic adjustment of Input/Output bandwidth for Virtual Machines of a Single Root Input/Output Virtualization (SRIOV) adapter. The SRIOV adapter includes a plurality of virtual functions (VFs). Each individual virtual function (VF) is enabled to be explicitly assigned to a Virtual Machine (VM); and each of a plurality of VF teams is created with one or more VFs and is assigned to a VM. Each VF team is enabled to be dynamically resizable for dynamic adjustment of Input/Output bandwidth.

Abstract: A network appliance is emulated in a logically partitioned environment. Activity of a logical partition (LPAR) acting as a network appliance is monitored. When a change in activity occurs in the LPAR acting as the network appliance, a set of business logic partitions served by the LPAR acting as the network appliance is determined, and resource utilization of each business logic partition served by the LPAR acting as the network appliance is determined. A determination is also made whether each business logic partition served by the LPAR acting as the network appliance needs more or less resources. Availability of resources is determined, and resources are allocated or deallocated to or from the business logic partitions served by the LPAR acting as the network appliance based on the need for resources and the availability of resources for each business logic partition.
