摘要： A method is provided for creating and managing tables for routing packets through an environment that includes multiple hosts and shared PCI switches and adapters. A Destination Identification (DID) field in the PBA is appended to a transaction packet dispatched through the PCI switches, wherein a particular DID is associated with a particular host or system image, and thus identifies the physical or virtual end point of its packet. In one embodiment, packets are routed through PCI switches in a distributed computer system comprising multiple root nodes, wherein each root node includes one or more hosts. The embodiment includes the step of creating a table or like data structure in a specified one of the switches. When a particular host of one of the root nodes becomes connected to the specified switch, a PCI Configuration Master (PCM), residing in one of the root nodes, is operated to enter a destination identifier or DID into the table. The DID is then appended as an address component, to packets directed through the specified switch from the particular host to one of the adapters. The destination identifier is also used to determine that a PCI packet, routed through the specified switch from one of the adapters, is intended for the particular root node.
摘要翻译：提供了一种创建和管理表以通过包括多个主机和共享PCI交换机和适配器的环境路由数据包的方法。 PBA中的目的地标识（DID）字段附加到通过PCI交换机分派的事务分组，其中特定的DID与特定主机或系统映像相关联，并且因此标识其分组的物理或虚拟终点。在一个实施例中，分组通过包括多个根节点的分布式计算机系统中的PCI交换机路由，其中每个根节点包括一个或多个主机。该实施例包括在指定的一个开关中创建表或类似数据结构的步骤。当一个根节点的特定主机连接到指定的交换机时，驻留在其中一个根节点的PCI配置主机（PCM）被操作以在表中输入目的地标识符或DID。然后，将DID作为地址组件附加到通过指定的交换机从特定主机引导到其中一个适配器的数据包。目的地标识符还用于确定通过指定交换机从其中一个适配器路由的PCI数据包是针对特定根节点的。

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 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.
摘要翻译：一种方法涉及在具有多个根节点的分布式计算机系统中使用主根节点来控制通过I / O交换结构的路由的配置。一个根节点被指定为主根节点或PCI配置管理器（PCM），并且可操作以在每个其他根节点保持处于静态或非活动状态的同时执行配置。在与上述类型的系统相关的一个有用的实施例中，其包括可用于不同根节点共享的多个根节点，PCI交换机和PCI适配器，提供了一种方法，其中主根节点被操作以配置通过PCI的路由开关。相应的路由被配置在相应的根节点和PCI适配器之间，其中每个配置的路由仅对应于根节点之一。特定根节点能够访问包含在与特定根节点对应的任何配置的路由中的每个PCI适配器。同时，主根节点将特定根节点只写入与特定根节点对应的已配置路由。因此，防止特定根节点访问未包括在其对应的路由中的适配器。

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.

摘要： A PCI control manager provides address translation protection tables in switches in a PCI fabric. The PCI control manager discovers the fabric and provides a virtual tree for each root complex. A system administrator may then remove endpoints that do not communicate with the root complex to configure the PCI fabric. The PCI control manager then provides updated ATPT tables to the switches. When a host or adapter is added, the master PCM goes through the discovery process and the ATPT tables and adapter routing tables are modified to reflect the change in configuration. The master PCM can query the ATPT tables and adapter routing tables to determine what is in the configuration. The master PCM can also destroy entries in the ATPT tables and adapter routing tables when a device is removed from the configuration and those entries are no longer valid.

摘要： In a distributed computer system having multiple root nodes, a challenge protocol is provided, for use in determining or confirming the root node in which a PCI Configuration Manager (PCM) actually resides. This node is referred to as the master node. The challenge procedure is activated whenever the identity of the PCM, which is determined by the root node in which it resides, appears to be uncertain. The challenge procedure resolves this uncertainty, and enables the PCM to continue to configure routings throughout the system. In a useful embodiment, a method is directed to a distributed computer system of the above type which is further provided with PCI switches and with adapters that are available for sharing by different nodes. The method includes the steps of selecting a first one of the root nodes to be master root node, and operating the first root node to query the configuration space of a particular one of the PCI switches. The method further includes detecting information indicating that a second root node is considered to be the master root node for the particular switch. A challenge protocol is implemented in response to this detected information, to seek confirmation that the first root node is the master root node. The configuration space querying procedure is continued if the first root node is confirmed to be the master root node, and is otherwise aborted.

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.
