Example method includes: negotiating, with a client device, a number of simultaneous I/O commands allowed in a single session between a storage device and the client device; pre-allocating a number of immediate data buffers for the single session based on the negotiated number of simultaneous I/O commands; receiving a write I/O command with immediate data, wherein the immediate data is transmitted within a single PDU as the I/O command; transitioning the pre-allocated buffers from a network interface state to a driver state in an atomic operation, the driver state enabling the pre-allocated buffers to be accessed by a driver layer of the storage device exclusively, and the atomic operation preventing other I/O commands from transitioning the network interface state of the pre-allocated buffers until the atomic operation is completed; and writing the immediate data to the pre-allocated buffers that are in the driver state.
