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!
