RE: Plone scaling and setup problems.
I don't have a good idea what the load will be. The current
sites receive about 700,000 to 800,000 requests per day. A large number
of teachers have trouble using common web authoring tools so we hope
that the number of users and amount of content increases. The Plone
interface with epoz makes it really easy for them.
I gather you are using ZEO images and object stubs then
PostgreSQL for applications. Is there much difference between using ZEO
and having the server access the Data.fs file directly?
The install problem that I was having was related to paths.
Some packages look for zope2.7 and others look at zope. When I first
install zope2.7 then symlink /usr/lib/zope and /etc/init.d/zope then
install plone life is good. The last time I installed plone from debian
packages, this was not necessary. I think the path changed from zope
2.6 to zope 2.7.

I am sure someone does. :)

Very well. :)
I use a dedicated PostgreSQL server database for relational data,
and I run ZEO and Zope together on one machine, exporting the Zope
instance over NFS. Whenever there is a real increase in traffic,
I can add additional Zope servers on the fly, but that's never been
the case.
Last year we handled a rather busy site with 1200 users
(tokyolectures.org) and rather big downloads (100Mb/file), and we
experienced no Zope-related problems.

I think you will be fine with a standard AMD, maybe even AMD64
(works nicely), some sensible network card (e.g. not Broadcom or
other El Cheapos), and a RAID 1 or 5 for your data partition.
Hardware RAID is a little faster than software RAID, but I have made
very good experiences with the latter.

Can you check the control panel's products listing for what it says
about Plone?
