Claim 7:
8. A network interface apparatus handling network protocols between a host and storage controller having a processor and a cache memory, the network interface apparatus being coupled to the storage controller and including a processor and a memory independently from the processor and the cache memory of the storage controller and connected to a network,
wherein when receiving at once, from the host, both data to be stored in a storage drive and a write request associated with the data via the network, the processor of the network interface apparatus performs protocol processing on the write request, stores the data and the write request at a reserved area being reserved before receiving the data and the write request, in the memory of the network interface apparatus and transfers a write command to the storage controller that does not contain the data,
when receiving a data transfer request from the storage controller, the processor of the network interface apparatus stores the data stored in the memory in a storage area specified by the data transfer request, and
when receiving a write response from the storage controller, the processor of the network interface apparatus performs the protocol processing to respond to the host.
