Abstract:
Aspects of a system for splicing RDMA transactions in an RDMA system may include a main processor within a main server that may receive read requests from a client device. The main processor may translate a data reference contained in each read request to generate a physical buffer list (PBL). The processor 206 may communicate the PBL to a local processor within a NIC. The local processor may utilize the PBL perform RDMA operations to retrieve data stripes contained in one or more DDP segments received from a plurality of auxiliary servers. The local processor may enable the generation of TCP packets each containing the data stripes, which may then be sent to the client. The retrieval of DDP segments and generation of TCP packets may occur within the NIC without transferring retrieved data stripes via a system bus within the main server.
