Exemplary embodiments provide methods, mediums, and systems for efficiently moving data between cluster nodes. Upon receiving a request to read or write data at a first cluster node that is in communication with a client, the first node effects the transfer to or from a second cluster node. The transfer is carried out using a combination of remote data memory access ('RDMA'), or a similar technique that bypasses a part of the network stack, and transport control protocol ('TCP'), or a similar technique that does not bypass a part of the network stack. The data is transferred using RDMA, while certain control messages are sent using TCP. By combining RDMA content transfers and TCP control messages, data transfers can be carried out faster, more efficiently, and with less processing overhead. Other embodiments are described and claimed.
