摘要： The embodiments described herein generally relate to a protocol for implementing data operations, e.g., a version of SMB, atop RDMA transports. In embodiments, systems and methods use the protocol definition, which specifies new messages for negotiating an RDMA connection and for transferring SMB2 data using the negotiated communication. A new protocol message may include new header information to determine message size, number of messages, and other information for sending the SMB2 data over RDMA. The header information is used to accommodate differences in message size requirements between RDMA and SMB2. The SMB Direct protocol allows SMB2 data to be fragmented into multiple individual RDMA messages that a receiver may then logically concatenate into a single SMB2 request or SMB2 response. The SMB Direct protocol also may allow SMB2 to transfer application data via efficient RDMA direct placement and to signal the application data's availability when the transfer is complete.
摘要翻译：这里描述的实施例通常涉及用于实现数据操作的协议，例如在RDMA传输上面的SMB的版本。在实施例中，系统和方法使用协议定义，其定义用于协商RDMA连接的新消息以及使用协商的通信来传送SMB2数据。新的协议消息可以包括用于确定消息大小，消息数量以及用于通过RDMA发送SMB2数据的其他信息的新的头信息。标题信息用于适应RDMA和SMB2之间的消息大小要求的差异。 SMB Direct协议允许SMB2数据被分段成多个单独的RDMA消息，接收者可以逻辑地连接到单个SMB2请求或SMB2响应中。 SMB Direct协议还可以允许SMB2通过高效的RDMA直接放置来传输应用数据，并在传输完成时向应用数据的可用性发出信号。
