Direct Attach vs Expander backplane


Recommended Posts

So..  my main server took a hit from a water pipe I didn't know existed. I have no idea what (if anything) lived through the ordeal, but I'm thinking it's a good time to get away from my Norco 4224 anyway.

 

Looking at Supermicro chassis, I see I have a backplane option of direct attached or expander.  I understand that using an expander will divide up available bandwidth amongst the drives, but the crux of my question is this: Does it split that bandwidth when drives are inactive? Since I'm often only using a couple drives at any given moment (aside from parity checks) would I even notice? Or is it always bandwidth/#connected drives no matter what they're doing? This seems especially critical for the cache drives.

 

Thanks
