Abstract
The present invention features a method for improving data flow from a host initiator on a first data bus to a target tape storage device on a second data bus, both buses being connected to one another by an I/O bridge or gateway. The inventive method allows the I/O bridge to return a slightly early write completion status to the host initiator before data is transmitted to the tape storage device and before the tape write operation is physically complete. The host initiator may then issue additional tape write commands and data may actually be transferred to buffer memory of the I/O bridge or gateway before the first tape write operation has been completed. This improves data throughput between host initiators and target tape storage devices, particularly in a storage area network (SAN).
