Abstract: Hypervisor managed memory paging is provided in a data processing system having multiple logical partitions. The data processing system includes a shared memory pool defined within physical memory. The shared memory pool includes a volume of physical memory with dynamically adjustable sub-volumes or sets of physical pages associated with the multiple logical partitions. Each sub-volume or set is associated with a particular logical partition and includes mapped logical memory pages for that logical partition. A hypervisor memory manager interfaces the multiple logical partitions and the shared memory pool, and manages access to logical memory pages within the shared memory pool. The hypervisor memory manager further manages page-out and page-in of logical memory pages from the shared memory pool to one or more external paging devices. This page-out and page-in managing by the hypervisor memory manager is transparent to the multiple logical partitions.

Abstract: Operating system-directed workload scheduling of an adjunct partition in a logically partitioned computer is selectively overridden to handle platform work requiring a Quality of Service (QoS) guarantee. Firmware may track outstanding requests for platform work for an adjunct partition, and in response to a request for platform work that requires a QoS guarantee, the firmware may assume or take over scheduling decisions for the adjunct partition from the operating system of an associated logical partition and schedule execution of the adjunct partition to ensure that the adjunct partition will be allocated sufficient execution resources to perform the platform work independent of the scheduling desires of the operating system. As a result, any platform work that potentially impacts the platform work of other adjunct partitions will not be held up as a result of an unwillingness or inability of the operating system to schedule execution of the adjunct partition.

Abstract: A firmware update process for a self-virtualizing IO resource such as an SRIOV adapter is incorporated into a platform firmware update process to systematically update the resource firmware in a manner that is for the most part transparent to the logical partitions sharing the adapter. In particular, resource firmware associated with a self-virtualizing IO resource is bundled with firmware for at least one adjunct partition associated with that self-virtualizing IO resource within a common firmware image so that, upon restart of the adjunct partition to use the updated firmware image, the resource firmware is also updated, with a logical partition that uses the self-virtualizing IO resource maintained in an active state during the restart, and without requiring the self-virtualizing IO resource to be deconfigured from the logical partition.

Abstract: A computer-implemented method may include determining a number of virtual functions that each port of a hardware input/output adapter is capable of supporting. The computer-implemented method may include assigning a first portion of internal resources of the hardware input/output adapter to each port of the hardware input/output adapter. The computer-implemented method may also include, for a particular port of the hardware input/output adapter, assigning a second portion of the internal resources to each virtual function that the particular port is capable of supporting. The second portion of the internal resources may be a subset of the first portion of the internal resources. The computer-implemented method may further include configuring a virtual function prior to a runtime to use the assigned second portion of the internal resources.

Abstract: A vendor independent interface is provided between a hypervisor and an adjunct partition associated with a self-virtualizing IO resource to effectively abstract away vendor-specific interface details for the self-virtualizing IO resource and its adjunct partition. By doing so, vendor-specific implementation details may be isolated from the configuration and management functionality in a hypervisor, thus minimizing the changes to vendor specific firmware in order to manage new or revised self-virtualizing IO resources.

Abstract: Systems and methods to forward data frames are provided. A particular method may include evaluating address data of a first data frame at a first virtual bridge coupled to a first virtual machine of a first server computer of a plurality of server computers. Based upon the evaluation at the first virtual bridge, the first data frame may be forwarded to a second virtual bridge associated with an adapter that is coupled to the first virtual machine. The address data of the first data frame may be evaluated at the second virtual bridge. Based upon the evaluation, the data frame may be forwarded to a third virtual bridge configured to forward the data frame based upon the address data to a second server computer of the plurality of server computers.

Abstract: Systems and methods to forward data frames are provided. A particular method may include receiving a data frame at a distributed virtual bridge. The distributed virtual bridge includes a first bridge element coupled to a first server computer and a second bridge element coupled to the first bridge element and to a second server computer. The distributed virtual bridge further includes a controlling bridge coupled to the first bridge element and to the second bridge element. The controlling bridge includes a global forwarding table. The data frame is forwarded from the first bridge element to the second bridge element of the distributed virtual bridge using address data associated with the data frame. A logical network associated with the frame may additionally be used to forward the data frame.

Abstract: Providing communications between operating system partitions and a computer network. In one aspect, an apparatus for distributing network communications among multiple operating system partitions includes a physical port allowing communications between the network and the computer system, and logical ports associated with the physical port, where each logical port is associated with one of the operating system partitions. Each of the logical ports enables communication between a physical port and the associated operating system partition and allows configurability of network resources of the system. Other aspects include a logical switch for logical and physical ports, and packet queues for each connection and for each logical port.
