Cool, sounds good.

Option 1 might be easier to set up and work with. Not sure about costs, 
though...

For small setups like this, you might want to use the Filesystem Glance 
storage driver targeted at the local filesystem and use the SAN+isci for 
the volume operations only.

This would make it a bit easier to diagnose issues and administer Glance.

Also, don't forget about MySQL, RabbitMQ and keystone. You need to put 
those on the controller node too! :)
