Hi Richard,

Cases like the Supermicro 846E1-R900B have 24 hot swap bays accessible

controller death and having the backplane as a single point of failure.
There will be dozens of single point failures in your system. Don't
worry about
controllers or expanders because they will be at least 10x more reliable
than
your disks. If you want to invest for better reliability, invest in
enterprise class
disks, preferably SSDs.

I agree about the points of failure, but I guess I'm not looking as much
for reliability as I am for replacability. The motherboard, backplane
and controllers are all reasonably priced (to the extent that if I had a
few of these machine I would keep spares of everything on hand). They
are also pretty generic so I could recycle them if I decided to go in a
different direction.
Thanks,
Ian.
