The configuration I use is only hardware fault tolerance. You are right 
that this doesn't protect me from buggy code.  

The hardware is not a supported configuration for Sun's HA/Clustering --  
I suspect Qualix could be made to work but this is exactly the complexity
I was trying to avoid.

You are probably looking at about $30k +/- 5k depending on configuration.
They only support a single sbus card -- QE and QFE are supported.  An ultra
is supposed to be coming out around March... Solaris 2.6 not supported yet.
