A system and method for improved remote direct memory access (RDMA) for multi-host network interface controllers (NIC), the method including: allocating a first key to a first host, the first key corresponding to a first address of a memory device of the first host; and allocating the first key to a second host, wherein the second host is an RDMA NIC (rNIC) configured to offload at least a portion of storage operations from the first host.
