Yep. What looks to be a small contract to recommend and then install for me...
and I've never done the first part before.

Except I'm waiting now to find out what kind of hits to expect. This is not a
personal site, but a business site, and they *could*, theoretically, get a good
number of hits. That's why I need to have some kind of numeric guidelines. I'm
figuring on virtualization, and at least two real servers for the web with two
VM's on each, and another for the d/b; don't begin to know enough to know
whether we'll need to mirror the d/b.

Um, low cost for rack mounts, that is.

I know. Not sure whether they'll need, or want to spring for, a load-balancing
appliance. I *may*, to start, just let VM handle that.
