There is nothing active/active about DRBD though, it also doesn't solve the
problem of trying to utilize two heads.

It's just failover. Nothing more.

I'm looking for an active/active failover scenario, to utilize the multiple
physical paths for additional throughput and bandwidth. Yes, I know I can
add more nics. More nics doesn't provide failover of the physical node.
