摘要： Apparatus, methods and systems for supporting Send with Immediate Data messages using Remote Direct Memory Access (RDMA) and the Internet Wide Area RDMA Protocol (iWARP). iWARP logic in an RDMA Network Interface Controller (RNIC) is configured to generate different types of Send with Immediate Data messages, each including a header with a unique RDMA opcode identifying the type of Send with Immediate Data message, and send the message to an RDMA remote peer using iWARP implemented over an Ethernet network. The iWARP logic is further configured to process the Send with Immediate Data messages received from the RDMA remote peer. The Send with Immediate Data messages include a Send with Immediate Data message, a Send with Invalidate and Immediate Data message, a Send with Solicited Event (SE) and Immediate Data message, and a Send with Invalidate and SE and Immediate Data message.

摘要： Apparatus, method and system for supporting Remote Direct Memory Access (RDMA) Read V2 Request and Response messages using the Internet Wide Area RDMA Protocol (iWARP). iWARP logic in an RDMA Network Interface Controller (RNIC) is configured to generate a new RDMA Read V2 Request message and generate a new RDMA Read V2 Response message in response to a received RDMA Read V2 Request message, and send the messages to an RDMA remote peer using iWARP implemented over an Ethernet network. The iWARP logic is further configured to process RDMA Read V2 Response messages received from the RDMA remote peer, and to write data contained in the messages to appropriate locations using DMA transfers from buffers on the RNIC into system memory. In addition, the new semantics removes the need for extra operations to grant and revoke remote access rights.

摘要： An embodiment may include circuitry that may write a message from a system memory in a host to a memory space in an input/output (I/O) controller in the host. A host operating system may reside, at least in part, in the system memory. The message may include both data and at least one descriptor associated with the data. The data may be included in the at least one descriptor. The circuitry also may signal the I/O controller that the writing has occurred.

摘要： A flexible arrangement allows a single arrangement of Ethernet channel adapter (ECA) hardware functions to appear as needed to conform to various operating system deployment models. A PCI interface presents a logical model of virtual devices appropriate to the relevant operating system. Mapping parameters and values are associated with the packet streams to allow the packet streams to be properly processed according to the presented logical model and needed operations. Mapping occurs at both the host side and at the network side to allow the multiple operations of the ECA to be performed while still allowing proper delivery at each interface.
