You could do it by writing a target mode tape driver to act like a tape drive and accept the data. Then it would pass the data to a userland program for storage on disk somewhere. Then you can grab the data off the disk and write it to the slow tape drive. I think the only controllers that we support target mode for now are the Adaptec 7890 and probably the 7895. Justin would know for sure. I think some of the Qlogic boards support target mode as well, I don't know if Matt has gotten the hooks in the driver yet. The practicality of doing something like this would depend on what you're trying to use to write the data. It would probably be a good bit easier to write the data over a network to the FreeBSD box, if that's possible.
