anyone here had experience of installing Zenworks 7 for desktop management?

I would be interested to read your experiences and recommended setups.

I have a test OES box and am planning on installing Zen 7. However, going
through the documentation here -
There is a mention of having a primary and secondary Zen 7 servers. My
question is, can I install Zen 7 on a standard oes box which also runs
iiPrint, SLES9 dhcp/dns and network file access? At most around 600 users
will be connected to the server.

Also, what is a 'Middle Tier Server'?
