Unless there's something else going on that I don't know about, I expect
this isn't a great idea. The hot spare is going to degrade (depreciate,
disk wear out - although not quite as fast, software need upgrading)
just as fast idle as doing work.
You may as well have both working all the time and for the few hours of
down time a year that you'll need for planned maintenance, you can make
do with one machine. If you only need the capacity of 1 machine, then
you can use two smaller machines instead.
