[rescue] Sun Ultra5 emulation, was: more sun2 adventures!

[Jonathan Katz]

The SF25k/15k has a built-in SSP. The E10K and CS6400s had external SSPs.
For the 10K were always sold as an active/passive SSP cluster for an
individual 10K. That said there seemed to be hooks in the SSP software
where it could talk to more than one platform; I think the visual app for
the SSP was called "hostview" and it seemed to be able to do multiple
systems. It would be a fun test for someone who didn't have to worry about
their electric bill.
