I currently run Untangle NG Firewall on Dell PE servers. I currently use HDD's in most of them. I'm looking for a temporary hot swap device that can be used in instance where HDD fails. Can I load Untangle to external SSD? Also, can I do this from any computer (running Windows 7) if I boot to ISO on CD. I just don't want to mess up anything on my Windows laptop when installing to USB SSD. Will Untangle let me choose which drive to install? Any help is appreciated.
