    摘要： An improved solution for limiting the transmission rate of data over a network is provided according to an aspect of the invention. In particular, the transmission rate for a port is limited by rate limiting one of a plurality of queues (e.g., class/quality of service queues) for the port, and directing all data (e.g., packets) for transmission through the port to the single rate limited queue. In this manner, the transmission rate for the port can be effectively limited to accommodate, for example, a lower transmission rate for a port on a destination node.

    摘要： Routing between multiple hosts and adapters in a PCI environment is provided by a method and system. A Destination Identification (DID) field is inserted in a field of the PCI bus address (PBA) of transaction packets dispatched through PCI switches. A particular DID is associated with a particular host or system image, and thus identifies the physical or virtual end point of the packets. The method and system may track connections such that when particular host of a root node becomes connected to a specified switch, a PCI Configuration Master (PCM), residing in one of the root nodes, is operated to enter a destination identifier or DID into a table. The DID is then inserted in the PBA of packets directed through the specified switch from the particular host to one of the adapters.

    摘要： Embodiments of the present invention address deficiencies of the art in respect to Fibre Channel (FC) switch interoperability and provide a novel and non-obvious data processing system, method and computer program product for obtaining multiple port addresses by a FC switch directly from a SAN fabric. In one embodiment, the system uses an N_Port connection from the last tier FC SAN switch to connect to the rest of the SAN fabric and employs the N_Port ID Virtualization (NPIV) Fibre Channel feature. The NPIV feature allows one physical FC port (N_Port) to login to a SAN fabric multiple times and receive unique N_Port IDs with each login. This allows the one physical FC port (N_Port) to act as multiple logical N_Ports.

    摘要： A computer-implemented method, apparatus, and computer usable program code are disclosed for migrating a virtual adapter from a source physical adapter to a destination physical adapter in a data processing system where multiple host computer systems share multiple adapters and communicate with those adapters through a PCI switched-fabric bus. The virtual adapter is first caused to stop processing transactions. All in-flight transactions that are associated with the virtual adapter are then captured. The configuration information that defines the virtual adapter is moved from the source physical adapter to the destination physical adapter. The in-flight transactions are then restored to their original locations on the destination virtual adapter. The virtual adapter is then restarted on the destination physical adapter such that the virtual adapter begins processing transactions.

    摘要： A method, mechanism and computer usable medium is provided for distributing I/O fabric errors to the appropriate root nodes in a multi-root environment. The case where the I/O fabric is attached to more than one root node and where each root can potentially share with the other roots the I/O adapter (IOA) resources which are attached to the I/O is addressed. Additionally, a method, mechanism and computer usable medium is provided by which errors detected in an I/O fabric may be routed to all root nodes which may be affected by the error, while not being reported to the root nodes that will not be affected by those errors. In particular, distributed computing system which uses the PCI Express protocol to communicate over the I/O fabric is addressed.

    摘要： A method is directed to use of a master root node, in a distributed computer system provided with multiple root nodes, to control the configuration of routings through an I/O switched-fabric. One of the root nodes is designated as the master root node or PCI Configuration Manager (PCM), and is operable to carry out the configuration while each of the other root nodes remains in a quiescent or inactive state. In one useful embodiment pertaining to a system of the above type, that includes multiple root nodes, PCI switches, and PCI adapters available for sharing by different root nodes, a method is provided wherein the master root node is operated to configure routings through the PCI switches. Respective routings are configured between respective root nodes and the PCI adapters, wherein each of the configured routings corresponds to only one of the root nodes. A particular root node is enabled to access each of the PCI adapters that are included in any configured routing that corresponds to the particular root node. At the same time, the master root node writes into a particular root node only the configured routings that correspond to the particular root node. Thus, the particular root node is prevented from accessing an adapter that is not included in its corresponding routings.

    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.
