摘要： A method, computer program product, and distributed data processing system for directly sharing an I/O adapter that directly supports adapter virtualization and does not require an LPAR manager or other intermediary to be invoked on every I/O transaction is provided. The present invention also provides a method, computer program product, and distributed data processing system for directly creating and initializing a virtual adapter and associated resources on a physical adapter, such as a PCI, PCI-X, or PCI-E adapter. Specifically, the present invention is directed to a mechanism for sharing conventional PCI (Peripheral Component Interconnect) I/O adapters, PCI-X I/O adapters, PCI-Express I/O adapters, and, in general, any I/O adapter that uses a memory mapped I/O interface for communications. A mechanism is provided for directly creating and initializing a virtual adapter and associated resources within a physical adapter, such as a PCI, PCI-X, or PCI-E adapter. Additionally, each virtual adapter has an associated set of host side resources, such as memory addresses and interrupt levels, and adapter side resources, such as adapter memory addresses and processing queues, and each virtual adapter is isolated from accessing the host side resources and adapter resources that belong to another virtual or physical adapter.

摘要： A system, method and computer program product for providing a shared memory translation facility. The method includes receiving a request for access to a memory address from a requestor at a configuration, the receiving at a shared memory translation mechanism. It is determined if the memory address refers to a shared memory object (SMO), the SMO accessible by a plurality of configurations. In response to determining that the memory address refers to the SMO, it is determined if the configuration has access to the SMO. In response to determining that the configuration has access to the SMO, the requestor is provided a system absolute address for the SMO and access to the SMO. In this manner direct interchange of data between the plurality of configurations is allowed.

摘要： Maintaining SAN access rights during migration of operating systems including assigning, to a virtual SAN interface adapter of a source virtualization intermediary (SVI′) on the source server, at least two world wide port names (WWPN), identifying devices coupled for data communications to the SVI through the primary WWPN; selecting a target physical SAN interface adapter on a target server available to a target virtualization intermediary (‘TVI’) having a target virtual SAN interface adapter; assigning to the target virtual SAN interface adapter the secondary WWPN; identifying devices coupled for data communications to the TVI through the secondary WWPN; determining whether the devices coupled to the SVI through the primary WWPN are also coupled to TVI through the secondary WWPN; migrating the operating system from the source server to the target server if the devices coupled to the SVI through the primary WWPN are also coupled to TVI through the secondary WWPN.

摘要： A method, computer program product, and distributed data processing system that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to track performance and reliability statistics per virtual upstream and downstream port, thereby allowing a system and network management to be performed at finer granularity than what is possible using conventional physical port statistics, is provided. Particularly, a mechanism of managing per-virtual port performance metrics in a logically partitioned data processing system including allocating a subset of resources of a physical adapter to a virtual adapter of a plurality of virtual adapters is provided. The subset of resources includes a virtual port having an identifier assigned thereto. The identifier of the virtual port is associated with an address of a physical port. A metric table is associated with the virtual port, wherein the metric table includes metrics of operations that target the virtual port.
