摘要： Processing of out-of-order data transfers is facilitated in computing environments that enable data to be directly transferred between a host bus adapter (or other adapter) and a system without first staging the data in hardware disposed between the host bus adapter and the system. An address to be used in the data transfer is determined, in real-time, by efficiently locating an entry in an address data structure that includes the address to be used in the data transfer.

摘要： Aggregation of contiguous data packets, such as contiguous I/O adapter stores, is disclosed. Commensurate with receiving data packets to be written to a memory, multiple contiguous data units of the data packets are aggregated into an aggregated data block. The aggregated data block is validated for writing to memory responsive to either the aggregated data block reaching a size which with inclusion of a next contiguous data unit in the aggregated data block would result in the aggregated data block exceeding a configurable size limit, or a next data unit of the plurality of data units to be written to memory being non-contiguous with the multiple contiguous data units.

摘要： A packet that represents unknown traffic for a virtual host is received. A first test is performed to ascertain whether or not a destination connection can be determined for the received packet wherein, if a destination connection can be determined, a second test is performed to ascertain whether or not one or more connection-specific resources required to send the packet to a virtual host memory corresponding to the destination connection are available. If a destination connection for the packet cannot be determined, the packet is passed to a store engine. If the one or more connection-specific resources are not available, the packet is passed to the store engine. The store engine obtains a free packet buffer from a FIFO memory. The store engine moves the packet into the free packet buffer and submits the free packet buffer to the elastic FIFO memory. A monitoring procedure is performed to detect both an availability of connection-specific resources and a presence of one or more waiting packets with a known destination connection. When (i) a destination connection with one or more waiting packets, and (ii) available connection-specific resources, are both detected, removing the packet from the local data store; allocating the one or more connection-specific resources required to send the packet to the virtual host memory corresponding to the connection destination; and writing the packet to the virtual host memory.
