On their site, they fail to mention disk. Let's see, a few T3's in a
rack... Not to mention site prep costs, install costs, etc. This is, of
course, assuming your datacenter has 12 30-amp lines available, as well as
the ability to cool over 60Kbtu/hr of system...

True. A lot depends on the application. Obvoiusly, a bunch of engineers
picking apart monster core files is a bit more intense than StarOffice...

I agree with the support savings (or we wouldn't be doing it @SUn, not
than I'm complaing, as I type this on my work-at-home 440MHZ U10...).
However, the Sunrays need their own network, so you might have some costs
there.

No, I could imagine they could do it, but if you were really
mission-critical, you'd have a pair of 'em clustered, to avoid a SPOF.
I will say this, though - none of us miss our U10's, the Sunrays are
quiet, fast, and it is so cool to snag your card on the way to another
office, then just plug it in and keep working. Handy as all hell for
meetings.
