I personally don't care for the idea of exposing mainframe DASD to other platforms at the hardware level -- too many security headaches.
Unless you have gigabit connectivity to your Unix system, I don't think any speed differences between disk an tape really matter. Assuming the data is highly compressible and your using IDRC, you could get up to 8-10MB/sec with 3490s -- which is in the same ballpark as most of today's DASD. I think the bottleneck could be on the network side where you may only get 4-5MB/sec bandwidth if the Unix box has the usual 10/100 NIC. I think Gil's suggestion would be the easiest and the best. If you can NFS-mount your Unix DASD from MVS, you should be able to write the output from Fast Unload directly to the Unix DASD. That way, there would be no need for FTP, or any intermediate storage. (You eliminate having to transfer 240GB to/from disk/tape.)
