System and method for improved RDMA techniques for multi-host network interface controllers

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to perform a process, the process comprising:

• allocating a first key to a first host, the first key corresponding to a first memory address of a memory device of the first host;
• 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;
• receiving from the first host a request to perform a storage read of a first storage block on a remote storage server, the request comprising the first key;
• and
• sending an RDMA message to the remote storage server from the second host with the first key, such that the rNIC will write the content read from the first storage block on the first memory address associated with the first key.

A system for multi-host network interface controllers (NIC), comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
• allocate a first key to a first host, the first key corresponding to a first memory address of a memory device of the first host;
• allocate 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;
• receive from the first host a request to perform a storage write of a first storage block on a remote storage server, the request comprising the first key;
• and
• send an RDMA message to the remote storage server from the second host with the first key, so that the rNIC will write the content read from the first memory address associated with the first key on the first storage block.
