Abstract
A network storage system includes a non-volatile memory to store data including a log of received data access requests, and a cluster interconnect adapter through which to send data to a cluster partner. The nonvolatile memory and the cluster interconnect adapter are implemented in a single device connected to an expansion bus in the network storage system. Communication with the nonvolatile memory is carried out using LDMA, and communication with the cluster partner is carried out using RDMA via the cluster interconnect adapter. LDMA and RDMA functionality are merged in a common software stack.
