I managed Tandem Nonstops and also Stratus FX machines.
Multiple redundant hardware paths, mirrored ram etc.
God they were awful. The conservatism of design meant that although the hardware was fine and redundant and reliable, the software was crap; user hostile and buggy.
They would have been far better off making reliable clusters rather than make a machine internally redundant.
And expensive. Something around a million dollars for a 75 MHz machine (Stratus) in 1997.
