    摘要： Hardware transmit and/or receive queues in a self-virtualizing IO resource are virtualized to effectively abstract away resource-specific details for the self-virtualizing IO resource. By doing so, a logical partition may be permitted to configure and access a desired number of virtual transmit and/or receive queues, and have an adjunct partition that interfaces the logical partition with the self-virtualizing IO resource handle the appropriate mappings between the hardware and virtual queues.

    摘要： 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.

    摘要： 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.

    摘要： An object in a tier of a multi-tier virtual storage system is saved while the storage system is active. The object to be saved in an upper-level tier in the multi-tier storage system is identified. Servers associated with lower-level tiers below the tier containing the object to be saved to obtain the latest data stored in the respective associated tiers, use temporary storage to store the obtained data and handle any modifications to the obtained data, and cause applications running in the respective tiers to quiesce. Once a copy of the identified object is made, the servers associated with the lower-level tiers are instructed to obtain the data from the temporary storage and resume quiesced applications running in the respective tiers.
