摘要： A vendor independent partition interface between a logical partition and an adjunct partition associated with a self-virtualizing IO resource is used to effectively abstract away vender-specific interface details for the self-virtualizing IO resource. By doing so, vender-specific implementation details may be isolated from the operating systems resident in logical partitions, thus requiring only changes in vendor specific firmware in order to support new or revised self-virtualizing IO resources.

摘要： The present invention relates to a method for the safe shut down of an operating system. The invention utilizes a shutdown-monitoring program that is running in an initiator operating system to periodically transmit and pass-through SCSI command to a SCSI target to determine if a shutdown operations is to be performed upon the operating system. In response to the SCSI command the SCSI target returns data back to the initiator operating system, wherein the shutdown-monitoring program analyzes the data. In the event that the shutdown-monitoring program determines that the operating system is to be shut down, then an operating system shutdown is initiated using at least one appropriate API that is provided by the operating system.

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.

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.

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： Multiple translation control entries (TCEs) at the same indices in multiple, same size TCE tables are mapped to facilitate data communication between a self-virtualizing input/output (IO) resource and a logical partition. First and second TCE tables used by an adjunct partition that interfaces a self-virtualizing IO resource with a logical partition may be identically sized, so that whenever a direct memory access (DMA) operation between the self-virtualizing IO resource and the logical partition is desired the same TCE entries in the first and second TCE tables may be used to perform a redirected DMA operation, and without the need to perform hashing or other mapping algorithms to map to the respective TCE entries in the respective TCE tables.

摘要： Automated management of partition service assignment to a virtual input/output (VIO) adapter is provided. Responsive to creation of a new partition service in a data processing system, a partition priority number is determined for the new partition service, and, for each VIO adapter, the partition priority numbers of the partition services currently assigned to that VIO adapter are summed. For a VIO adapter with a lowest sum of partition priority numbers, logic determines whether assigning the new partition service to that VIO adapter results in its summed partition priority number being above a predefined threshold, and the new partition service is assigned to a VIO adapter based, at least in part, on whether assigning the new partition service to the VIO adapter with the lowest sum of partition priority numbers results in that VIO adapter's summed partition priority number exceeding the predefined threshold.

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.
