Two boxes have two CPU's, two power supplies etc in the same production line and
the total is thus =less= reliable than a single box solution.
If the power supplies are equal and each statistically break down once in ten
years in total that becomes once in five years.
By the way, the same applies for RAID, more concurrent harddisks definitely
means =more often broken drives=. Although the system won't break down if well
designed, you still have to do more repairs. Five drives instead of one: Five
times as much disks to repair/replace.
Good is often to have a spare, pre installed(!), "DSL router and modem", better
is to have a concurrent and tested(!) backup channel. Best is to have a working
backup channel: CARP!
