    Abstract: PROBLEM TO BE SOLVED: To provide a system and method for hot plug/remove of PCIe fabric, etc. SOLUTION: The addition of a new component in the fabric is detected and an event is sent to a multiple root fabric configuration manager. The multiple root fabric configuration manager gathers information about the new component and updates its I/O component tree structure in its configuration data structure to include the new component. The new component may then be utilized via the updated configuration data structure. When a component is to be removed, the multiple root fabric configuration manager receives an event indicating the component to be removed, determines which branches of the tree structure are affected by the removal, and updates its configuration data structure accordingly to remove the component and its associated components from the virtual plane of the removed component.

    Abstract: A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter (730) is provided. The connection establishment mechanism provides the ability to offload connection establishment (1030) and maintenance of connection state information to the offload network adapter (730). As a result of this offloading of connection establishment (1030) and state information maintenance, the number of communications needed between the host system (710) and the offload network adapter (730) may be reduced. In addition, offloading of these functions to the offload network adapter (730) permits bulk notification of established connections and state information to the host system (710) rather than piecemeal notifications as is present in known computing systems.

    Abstract: PROBLEM TO BE SOLVED: To provide a system and method for communication between host systems using socket connection and shared memories. SOLUTION: In the socket-based communication, a work queue in host systems can be used to listen for an incoming socket initialization request. As shown in Fig. 10, a first host system 1010 wishing to establish socket communication connection with a second host system 1020 can generate a socket initialization request work queue element in its work queue and can inform the second host system 1020 that the socket initialization request work queue element is available for processing. Then, the second host system can accept or deny the request. When the second host system accepts the request, the second host system returns a second half of a socket parameter for use by the first host system in performing socket based communications between the first and second host systems.

    Abstract: PROBLEM TO BE SOLVED: To share PCI adapters between multiple blades.
    SOLUTION: The present invention relates to a method for routing PCI transaction packets through switches between hosts and adapters in a distributed computing system that includes multiple route nodes, one or more PCI switches and PCI adapters, wherein each route node includes multiple hosts and one of the route nodes includes a PCI configuration manager (PCM). A table is created within specified one of switches and when a particular host is connected to the specified switch, a destination identifier including a set of bits designated by operating the PCM is entered to the table. The destination identifier is appended as an address to PCI packet directed through the specified switch from the particular host to one of the adapters. The destination identifier is used to determine that a PCI packet, routed through the specified switch from one of the adapters, is intended for the particular host.

    Abstract: A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided. The memory management mechanism permits both buffered sending and receiving of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism permits grouping of DMA buffers that can be shared among specified connections based on any number of attributes. The memory management mechanism further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system in bulk, and expedited transfer of data to the host system.
