there's another problem, if all 10000 cards with the same name, if some cards are down, how can you tell which one is down, after all you have to restart them to go to work again

I've seen some top miner's homepage on flypool.org,like this one:

 i was curious that how could one rig have a hashrate like 1.4MH/s, this is zcash we're talking about, think a nvidia 1060 can only do 300h/s. Is this one an ASIC miner ?  Could someone possibly invent an ASIC machine?
