    摘要： A method in a node for managing authorized attempts to access the node. A packet is received from a source, wherein the packet includes a first key. A determination is made as to whether the first key matches a second key for the node. The packet is dropped without a response to the source if the first key does not match the second key. Information from the packet is stored in response to this absence of a match. The information is sent to a selected recipient in response to a selected event, which may be, for example, either immediately or in response to polling to see if the information is present.

    摘要： A method, system, and product in a data processing system are disclosed for managing data transmitted from a first end node to a second end node included in the data processing system. A logical connection is established between the first end node and the second end node prior to transmitting data between the end nodes. An instance number is associated with this particular logical connection. The instance number is included in each packet transmitted between the end nodes while this logical connection remains established. The instance number remains constant during this logical connection. The instance number is altered, such as by incrementing it, each time a logical connection between these end nodes is reestablished. Thus, each packet is associated with a particular instance of the logical connection. When a packet is received, the instance number included in the packet may be used to determine whether the packet is a stale packet transmitted during a previous logical connection between these end nodes.

    摘要： An apparatus and method for implementing multicast in system area network channel adapters are provided. With the apparatus and method, a multicast packet is received in a channel adapter of an end node. The channel adapter determines which local queue pairs are party of the multicast group identified by a destination local identifier in the multicast data packet. Based on this determination, the channel adapter replicates the data packet and delivers a copy of the data packet to each local queue pair that is part of the multicast group.

    摘要： The system I/O interface and its data structure are designed to minimize the host CPU utilization in driving an adapter. The interface is also designed to reduce the system interference in processing I/O requests. To eliminate the need of using PIO instructions, the command/status blocks for exchanging messages between the system and the adapter reside in the system memory. The data structure is designed to avoid "share write" entries in order to further minimize the overhead of maintaining each coherency when updating an entry in the cache either concurrently or sequentially by both adapter and system CPU. Further, the data structure of the control and status blocks is resided in the system memory. The system CPU uses STORE instruction to prepare control blocks and LOAD instruction to read from completion status blocks; while the adapter will rely on its DMA engine to move data to/from system memory in accessing control/status blocks.

    摘要： A method, program and system for associating memory windows with memory regions in an infiniband data storage system are provided. The invention comprises registering a Memory Region, wherein the Memory Region is a set of virtually contiguous memory addresses defined by a virtual address and length. The system then establishes and maintains a Window Reference Count (WRC) for the Memory Region, which tracks the number of Memory Windows which are bound to the Memory Region. When the system binds a Memory Window to the Memory Region, the value of the WRC is incremented. When a Memory Window is unbound from the Memory Region, the value of the WRC is decremented. If no Memory Windows are bound to the Memory Region, the value of the WRC is zero. The Memory Region is not deregistered unless the value of the WRC equals zero.

    摘要： A method, computer program product, and data processing system for sharing memory protection tables and address translation tables among multiple Host Channel Adapters are disclosed. The protection and address translation tables for a shared memory region are written in memory of the host. The Host Channel Adapters are registered with the memory region so that each adapter stores an address pointer to the tables. In this way, the tables need not be duplicated for each adapter.
