This was my thought; depending on how much RAM you have in each blade, you
could have two virtual servers on each blade, one server being HTTP and
one being Postgres.
I'm not sure how big your application is, but if it's not the next SAP
then you might be able to get away with as little as 1G of RAM per blade
(on the dev and QA instances anyway), if you virtualize Linux servers
using XEN. That's the way I'd do it.
Cheers,
