What do you mean by netscape, the web browser? Or the old netscape web
server (iplanet)?

Does it have to be? That sounds like a perfect case for zones on 1
physical server. There is no possibility of accessing one zone from
another, it is secure.

It'll all depend how much memory you need, how many transactions per
second etc you need. What is the budget? What is the motivation to
move from 1 server to multiple servers?

Zones are only available with Solaris.

We've gone the inverse way. Collapse a bunch of servers on T1000,
using zones. Saved money, saved support, saved rack space, saved
power, saved cooling etc. You might want to look at T5220 on the sparc
side (64 thread, that's 2 per virtual server), or if you dont need as
much concurrency but sheer single process speed is more important,
look at the X4450 if your current server cant handle the load (or even
an X4600).

If it is for ressource reservation, then definitely look at zones +
caps (=container) in Solaris.
