摘要： An enhanced fibre channel adapter with multiple queues for use by different server processors or partitions. For a non-partitioned server, the OS owns the adapter, controls the adapter queues, and updates the queue table(s). An OS operator can obtain information from the fibre channel network about the fibre channel storage data zones available to the physical fibre channel adapter port and can specify that one or more zones can be accessed by a specific processor or group of processors. The processor or group of processors is given an adapter queue to access the zone or zones of storage data. This queue is given a new World Wide Port Name or new N-Port ID Virtualization identifier, to differentiate this queue from another queue that might have access to a different storage data zone or zones. For a partitioned server, one partition owns the adapter, controls the adapter queues, and updates the queue table(s). The partition management tool can obtain information from the fibre channel network about the fibre channel storage data zones available. A system operator can assign one or more storage zones under a fibre channel storage adapter to a partition. Each partition that has access to a zone or zones under an adapter is given an adapter queue to access the zone or zones. This queue is given a new World Wide Port Name or new N-Port ID Virtualization identifier, to differentiate this queue from another queue that might have access to a different storage data zone or zones.

摘要： A method, system and computer program product that allows a System Image within a multiple System Image Virtual Server to maintain isolation from the other system images while directly exposing a portion, or all, of its associated System Memory to a shared PCI Adapter without the need for each I/O operation to be analyzed and verified by a component trusted by the LPAR manager.

摘要： A mechanism that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to perform I/O transactions using the PCI host bus, device, and function numbers to validate that an I/O transaction originated from the proper host is provided. Additionally, a method for facilitating identification of a transaction source partition is provided. An input/output transaction that is directed to a physical adapter is originated from a system image of a plurality of system images. The host data processing system adds an identifier of the system image to the input/output transaction. The input/output transaction is then conveyed to the physical adapter for processing of the input/output transaction.

摘要： A mechanism for modifying resources in a logically partitioned data processing system is provided. A request to modify resources associated with a virtual adapter allocated on a physical adapter is invoked. The resources associated with the virtual adapter comprise a subset of the physical adapter resources. The request to modify the physical adapter is conveyed to the physical adapter. Responsive to receipt of the request by the physical adapter, the physical adapter modifies the resources allocated to the virtual adapter.

摘要： A method, computer program product, and distributed data processing system that enables host software or firmware to map PCI adapter virtual resources to PCI bus addresses that are associated with a system image is provided. Virtual addresses maintained in a protection table segment assigned to a system image are mapped to physical addresses defined in entries of an address table segment assigned to the system image. Discontiguous memory regions identified in entries of the address table segment may thus be mapped to a contiguous virtual address space.

摘要： A number of DMA addresses are resolved to system memory addresses at a time to decrease latency time. The number of addresses resolved at a time is preferably correlated to the number of DMA addresses that can be stored in a single cache line. Additionally, system memory is allocated in larger blocks that can store all of the information from the DMA addresses in a cache line. No change is required to the operating system, which can continue to operate on the page size it is set for. All changes are made in the hardware mapping programs and in the device driver software.

摘要： A method, apparatus, and computer program product are disclosed in a shared processor data processing system for coordinating error reporting for and resetting of a physical I/O adapter that supports virtualization. The physical I/O adapter is virtualized by generating virtual I/O adapters that each represent a portion of the physical I/O adapter. Each one of the virtual I/O adapters is assigned to a different one of client logical partitions. A determination is made regarding whether the physical I/O adapter may have experienced an error. If the physical I/O adapter has experienced an error, all of the client logical partitions are notified about the error and a recovery of the physical I/O adapter is coordinated among all of the client logical partitions by waiting for each client logical partition to acknowledge the error notification before the physical I/O adapter is reset.
