Thanks to all for the answers ! Specifically the fact that no additional
controllers are in the way is a great relief, given our last desaster
recovery adventure with SAS controller and expander hardware, which is
still below the 50% mark thanks to slow, partly unhealthy disks and
broken chips.
That totally convinced me that conventional disks and their hardware
layer requirements are no longer the way to go, apart from mostly
archival applications where there's not so much action ongoing as
in our live NFS servers for a lot of computational clients that
tests the mechanical endurance of the disks to the max. When I now
see ~ 1 nm flight height on modern disk heads and feel the heavy
trucks running along our institute in the guts, I don't think that
the undeniably astonishing advances in mechanical engineering are
practically advantageous for everyday usage any more ...
