摘要： A system and method for providing a memory region/memory window (MR/MW) access notification on a system area network are provided. Whenever a previously allocated MR/MW is accessed, such as via a remote direct memory access (RDMA) read/write operation, a notification of the access is generated and written to a queue data structure associated with the MR/MW. In one illustrative embodiment, this queue data structure may be a MR/MW event queue (EQ) data stricture that is created and used for all consumer processes and all MR/MWs. In other illustrative embodiments, the EQ is associated with a protection domain. In yet another illustrative embodiment, an event record may be posted to an asynchronous event handler in response to the accessing of the MR/MW. In another illustrative embodiment, a previously posted queue element may be used to generate a completion queue element in response to the accessing of the MR/MW.

摘要： Mechanisms for collective send operations on a system area network are provided. The mechanisms of the illustrative embodiments provide for the creation, modification, and removal of collective send queues (CSQs) that allow the upper level protocol (ULP) used by a consumer to send the same message to a collective set of queue pairs (QPs). In order to use the transport services of a CSQ, a consumer process posts a write work request (WR) to the CSQ. The write WR causes a write work queue element (WQE) to be generated and placed in the CSQ. A channel interface (CI) is provided that effectively copies the write WQE to all of the send queues (SQs) of the QPs in the QP set associated with the CSQ. When all the QPs complete processing of their respective write WQEs, the HCA releases all data segments referenced by the write WR.

摘要： A method of providing a converged InfiniBand over Ethernet (IBOE) network. An IBOE switch receives a data packet. If the data packet is received by the IBOE switch from the InfiniBand network, a translation utility looks up an Ethernet media access control (MAC) address corresponding to an LID of the packet in a translation table. The translation utility generates an Ethernet packet and encapsulates an InfiniBand link layer packet before sending the packet. If the data packet is received by the IBOE switch from the Ethernet network, the translation utility removes the Ethernet header from the packet and looks up a LID corresponding to the MAC address. The translation utility calculates an outbound port number and sends the packet.

摘要： A method of providing visibility of Ethernet components to a subnet manager in a converged InfiniBand over Ethernet (IBOE) network. If a port of an IBOE gateway corresponds to one or more InfiniBand devices, the subnet manager sends fabric management packets (FMPs) to discover the InfiniBand network and assigns physical local identifiers (LIDs) to the InfiniBand devices. If a port of the IBOE gateway corresponds to one or more Ethernet devices, the subnet manager sends FMPs to discover the Ethernet network. The subnet manager adds the Ethernet Media Access Control (MAC) addresses of any responding devices to an LID routing table and assigns LIDs to the Ethernet devices. The subnet manager configures one or more virtual Host Channel Adapters (HCAs) corresponding to the one or more Ethernet MAC addresses in the LID routing table.

摘要： Registering memory space for an application is performed. One or more open calls are received from an application to access one or more input/output (I/O) devices. Responsive to receiving the one or more open calls, one or more I/O map and pin calls are sent in order to register memory space for the one or more I/O devices within at least one storage area that will be accessed by the application. A verification is made as to whether the memory space to be registered is associated with the application. Responsive to the memory space being associated with the application, at least one virtual I/O bus address is received for each registered memory space of the one or more I/O devices. At least one I/O command is executed using the at least one virtual I/O bus address without intervention by an operating system or operating system image.
