摘要： A computer-implemented method, apparatus, and computer program product are disclosed for routing error messages in a multiple host computer system environment to only those host computer systems that are affected by the error. The environment includes multiple host computer systems that share multiple devices utilizing a switched fabric. An error is detected in one of the devices. Routing tables that are stored in fabric devices in the fabric are used to identify ones of the host computer systems that are affected by the error. An error message that identifies the error is routed to only the identified ones of the host computer systems.

摘要： Mechanisms for migration stateless virtual functions from one virtual plane to another are provided. When a migration of a source virtual function to a destination virtual function in another virtual plane is to be performed, a source single root PCI manager (SR-PCIM) is first interrupted by a multiple root PCI manager (MR-PCIM). Configuration information that defines the source virtual function is then redefined on the destination virtual function for this stateless migration. A function level reset may then be performed on the source virtual function. The destination SR-PCIM may be interrupted by the MR-PCIM with an interrupt for the destination virtual function. A function level reset may then be performed on the destination virtual function. The destination virtual function state may then be changed to an “active” state such that the migrated virtual function begins processing transactions.

摘要： A mechanism is provided that enables user space middleware or applications to pass file name based storage requests directly to a physical I/O Adapter without run-time involvement from the local Operating System (OS). A mechanism is provided for using a file protection table (FPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), to control user space and out of user space Input/Output (I/O) operations. In addition, a mechanism is provided for managing the FPT based on user space operations to create, query, modify and delete entries in the FPT.

摘要： A network system supports multiple network communication protocols. An Ethernet component gateway in a Fibre Channel over Ethernet (FCoE) initiator system converts FCoE data packets from host devices to Fibre Channel over Internet Protocol (FCIP) data packets for transmission to a Storage Area Network (SAN) target system. The SAN target system may include a target Fibre Channel (FC) storage device and a SAN component gateway. The SAN component gateway converts FCIP data packets to SAN data packets for use by the target FC storage device. The SAN data packets may be either FC protocol data packets or FCoE protocol data packets. The SAN target system may provide for discovery of target FC storage device adapter information.

摘要： Mechanisms are provided for implementing a multi-root PCI manager (MR-PCIM) in a multi-root I/O virtualization management partition (MR-IMP) to control the shared functionality of an multi-root I/O virtualization (IOV) enabled switch fabric and multi-root IOV enabled I/O adapter (IOA) through the base functions (BF) of the switches and IOAs. A hypervisor provides device-independent facilities to the code running in the I/O Virtualization Management Partition (IMP), Multi-Root (MR)-IMP and client partitions. The MR-IMP may include device specific code without the hypervisor needing to sacrifice its size, robustness, and upgradeability. The hypervisor provides the virtual intermediary functionally for the sharing and control of the switch and IOA's control functions.

摘要： A system for using a virtual switch in a network. In response to a switch connecting to a network, network configuration data is read to determine whether the switch is part of a virtual switch. In response to determining that the switch is part of the virtual switch, a priority number for the switch is sent to other switches connected to the network. Priority numbers are received from the other switches. It is determined whether the switch has a highest priority number. In response to determining that the switch does have the highest priority number, the switch is selected to be a master switch for the virtual switch. Then, domain identification data for the virtual switch is sent to the other switches. Afterward, the switch and the other switches respond to requests over the network as one domain identified by the domain identification data.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed for bus/device/function (BDF) translation and routing of communications packets through a fabric that utilizes PCI switches. Identifiers are included in communications packets that are routed between a host and an I/O adapter using a PCI fabric to which the host and the I/O adapter are coupled. Destination identifiers that are included in first communications packets that are received by edge switches, which are connected directly to said host or directly connected to said I/O adapter, are translated before routing the communications packets out of the edge switches. Second communications packets that are received by internal switches, which are not directly connected to the host or directly connected to the I/O adapter, are routed without translating destination identifiers that are included in the second communications packets.

摘要： Method and system for address routing in a distributed computing system, such as a distributed computing system that uses PCI Express protocol to communicate over an I/O fabric. A destination identifier is provided to identify a physical or virtual host or end point. When a physical or virtual host or end point receives a PCI data packet it compares a list of source identifiers with destination identifiers to determine if a source identifier included in the transaction packet is associated with a destination identifier included in the transaction packet to determine if the transaction packet has a valid association. If the transaction packet has a valid association, it is routed to the target device. The present invention enables each host that attaches to PCI bridges or switches and shares a set of common PCI devices to have its own PCI 64-bit address space and enables the routing of PCI transaction packets between multiple hosts and adapters, through a PCI switched-fabric bus using a destination identifier.

摘要： A method and apparatus is provided for routing error messages in a distributed computer system comprising multiple root nodes, and further comprising one or more PCI switches and one or more I/O adapters, wherein each root node includes one or more system images. In one useful embodiment, a method is provided for routing I/O error messages to root nodes respectively associated with the errors contained in the messages. The method includes detecting occurrence of an error at a specified one of the adapters, wherein the error affects one of the system images, and generating an error message at the specified adapter. The method further comprises routing the error message from the specified adapter to the particular root node that includes the affected system image. The error message is then selectively processed at the particular root node, in order to identify the affected system image. Usefully, the step of routing the error message includes using a bus/device/function number associated with the error, together with a routing table located in one of the PCI switches, to route the error message to the correct root node and system image.
