Nope. Solves the problem of hanging rigs when you are not on site. It's pretty obvious what he needs to do is stop building 2 gpu rigs.
I use CPU hardware. Servers, some small some big. I build what I can afford, and use what I have. My small machines are used for testing, the big ones are for production after I verify my tests on a small scale.
"build bigger rigs" is an easy answer. Buying new / different hardware is not an option. I did not ask "how do I get more hash power ?". Please remain focused on the topic.
