Agree but it requires me to be in physical proximity of the system.
My objective is to make the "HDD failure recovery" process as
deterministic as possible.  As stated in another response, this will
be an appliance running 24x7 at sites where Linux admin knowledge is
likely to be sparse and some sites may not give me connectivity over
the 'Net.

OK, I have understood the value of hot swap bays for disk failure scenario.
