Okay, this admittedly isn't desktop computer but server computer instead. I hope this is okay...

Can someone tell me how this backup device is supposed to connect to a server? I've never setup one of these and an associate of mine is looking to buy one. It's unclear to me what he'll need to connect it to the server. He has a RAID controller in his server (a small HP tower server) and it has an external connection to it, but I don't think you're supposed to connect this to a RAID controller. Maybe I'm wrong. I think he'll need to buy an add-on card, but what kind? That's where I'm stuck.
