Virtualization 101 - lecture on server, storage, network virtualization?

Hello,

I was asked by a valued customer if I have a recommendation for some background reading for a newbee at a customer on virtualization (server, storage, networks).

I pointed hime to Scott Lowe's and Dennis Zimmer's books, but they are in fact too deep and focused on VMware.

The presentation that Marcel Brunner brought to my attention on the team FTP /Home/vspecialist/Presentations/Virtualization in General/ - virtualization 101 seems to be outdated (mentioning Invista and alike...). But the content would look into the right direction.

Anybody aware of some good reading or other sources for a virtualization newbee who needs it as well for university studies?

Thank you!

David
