Thanks for all the great info. and suggestions. I have another question regarding memory and vm. One of the sales reps was saying that memory on the z/Series under z/vm had a 10 to 1 ratio over memory on intel, meaning if we had a intel box using 10 gig of ram that we would only require 1 gig of ram on z/VM. I know you can do some trickery under vm but is 10 to 1 really feasible?

Escon is only about 150Mbit, so both your disk bandwidth and your processing power will be significantly less than what you currently have. I don't want to say don't bother, but it will be "challenging".... >Date: Wed, 18 Aug 2004 09:58:01 -0400 >Sender: Linux on 390 Port <[EMAIL PROTECTED]> >From: Doug Griswold <[EMAIL PROTECTED]> > >What kind of performance can I expect out of a z800 with one >engine dedicated to linux with 1 gig of ram?
