The self-heal daemon that runs on the server is also a client process in 
the sense that it has client side xlators like ec or afr and  
protocol/client (see the shd volfile 'glustershd-server.vol') loaded and 
talks to the bricks like a normal client does.
The difference is that only self-heal related 'logic' get executed on 
the shd while both self-heal and I/O related logic get executed from the 
mount. The self-heal logic resides mostly in afr-self-heal*.[ch] while 
I/O related logic is there in the other files.
