A cloud gaming system includes a storage system and a compute system connected through a PCIe fabric. The compute system generates a command buffer for a read operation, writes the command buffer to storage system memory, and notifies the storage system about the command buffer. The storage system reads the command buffer in its memory and processes the command buffer to read requested data. In one embodiment, the storage system writes the requested data in the storage system memory and notifies the compute system about the requested data in the storage system memory, and the compute system reads the requested data from the storage system memory. In another embodiment, the storage system writes the requested data in the compute system memory and notifies the compute system about the requested data in the compute system memory, and the compute system reads the requested data from the compute system memory.
