I am also stuck trying to sort out networking so Josh has my sympathies.
The networking docs are really confusing.
They wander from general to specific.
They mix the general architecture with specific hardware discussions
without any context for the switch or any explanation of why the
hardware specific note needs to be known to everyone.
I have earlier made specific suggestions about how reorganize the docs
but no one seems to be working in this area.
I think that part of the problem is that the larger organizations have
dedicated network experts who are working in networking everyday whereas
smaller organizations have generalists and once the network is set up,
it runs on its own for years until you want to do something like Cloudstack.
To help this type of user, the docs need to be reorganized and simplified.
The Shapeblue article is much better than the Cloudstack docs.
It is great that it is available but the official docs should be improved.
I did ask where the drawing sources are located but did not get a response.

Hello Josh,
Networking is the single biggest cause of headaches with Cloudstack, once you
get it right the rest is easier.
I recommend to read

Advanced Zone with Security Groups.
I have a ACS+Xenserver setup and when I go to Infrastructure > Primary Storage I
definitely see "iscsi" as an option in the storage type.

Subject: Really really confused about Cloudstack networking
I have been tinkering about cloudstack but every single guide seems to be
centered around the public IPs being NATed to the guest VMs. To be honest the
more I think about it the more I get confused so I'm posting here in hopes that
someone will guide me through this.
I have tried to pen down what I'm looking for and I hope it's clear enough:- I
have a block of public routable IPs which I want to assign to individual VMs-
These VMs run linux and are intended to function as web servers- I have no need
for inter-VM private interactions except for via the public network- These VMs
all reside in a single cloudstack cloud for high availability and resource
balancing- The HVs in the cloud are connected to a central SAN running iSCSI-
The HVs run XenServer
I'm confused with:- Do I set the guest network as the public IP range?- Internal
DNS = Public DNS?- Does the management server need to have access to the
storage network?- Why don't I have the option to choose iSCSI when I try to add
a primary storage?- Basically everything
