Does Cisco Mars come only on box or could I get the software and install it onThe short answer: No. But why? I'm sure in a way it has to do with costs and how Cisco is able to required Cisco hardware to be used. There's also less cynical reasons. One that I know of is that MARS is using Oracle embedded for it's database. As part of using Oracle on an appliance and having it licensed as embedded, is that the distributor of the appliance must no allow users to alter the database or exploit it for unlicensed purposes. Mandating the use of a purchased appliance keeps greater control over how the software is installed and the experience it provides to it's users. Hope this helped!
