Abstract
A method and system provide access assurance regarding an RDMA transaction. The system comprises an initiating device and a target device placed across a network. The initiating device and the target device are coupled to a first and a second buses, respectively. The first and the second buses are coupled to the network router through a first and a second network adaptors. An RDMA space and an associated access assurance space are assigned to the target device in the memory space of the first bus. The initiating device may RDMA the target device by directly reading from or writing into the RDMA space assigned to the target device. To obtain access assurance information regarding the RDMA transaction, the initiator performs a read from the assurance space associated with the RDMA space of the target device in the memory space of the first bus.
