Hello all, I am slowly getting together all my stuff to put together 2 Catalyst racks and hopefully 2 more by the new year. I have a few questions and I hope someone has some solutions or good options for me. In each rack I am thinking about having a Mac Pro as the main computer and having a good beefed up Mac Mini as a backup. Is it possible to have some sort of USB A-B switch so that both machines in the rack could use the same dongle? For example, if main machine went down, the user could switch to the Mac Mini backup and switch the dongle over to the Mac Mini. Im trying to come up with a nice way to pull this off without having to invest in a dongle for a back up machine. But, I would like to somehow make the transition from Main to Back up as quick and seamless as possible. What do you guys think? Anyone have any suggestions for this? Thanks for any help, Matt
