Brad, Sounds like a great product. With the volume id and seqnbr that is supplied when you copy to and from tape, your device could be a file system onto itself. With access to data stored at an ip addr, you might be able to enable an unattended ptf and/or release upgrade. ( no need to load the next volume ) All devices on the system ( tape, display, printer ) can be varied on and off. Will your tape emulator respond to the VRYCFG cmd ? Will all types of save and restores be supported ? Esp system type saves like SAVSYS and SAVSECDTA. When you restore the system after a crash you mount your SAVSYS tape on the tape drive and IPL the system from source D. Will the TE ( tape emulator ) support this operation ? I question that the save will run any faster than it does to a real tape drive. Save to save file does not run any faster than save to tape. Have you seen actual faster save results ? Have you reverse engineered the data stream format used on tape operations ? Or has IBM supplied it to you ? Can you explain the format of the tape data stream ? More questions where these came from.
