A single box of any type absolutely cannot deliver eight nines. Maybe a sysplex running very limited software...

Tell that to my Linux boxes that have been up for years, or others who have been up for decades.

I would suspect that it IS multiple boxes and with z/VM using single system image. This is the first time I've ever heard of mainframe "in a rack". In the past they come in their own cabinet, but if you open the cabinet door you won't see one "box".

No, it's a single box with one Telum chip.

I mean it's susceptible to fire an ac/cooling failure - other than that? Redundant power, redundant connectivity are both feasible?
