RabbitMQ nodes in a cluster don't have any roles (broadly speaking, some nodes host
management database statistics but it's not particularly important). So you can consider
to be "all the same".

They are all stored in the internal database of a node. There are no separate queue nodes
or exchange nodes.

See http://www.rabbitmq.com/tutorials/amqp-concepts.html just in case.

Not sure what exactly do you mean but take a look at

http://www.rabbitmq.com/distributed.html
http://www.rabbitmq.com/ha.html
http://www.rabbitmq.com/clustering.html
http://www.rabbitmq.com/shovel.html
http://www.rabbitmq.com/reliability.html

You don't need to provide shared storage and if you want to achieve high availability
and good throughput, it's not a good idea.

> ·         I understand the software and data needs to co-exist on the same volume or disk as the OS as one large disk, is this true.  I’d rather install the OS RHEL and software data in different drives, best practice???

You can move RabbitMQ database, configuration and so on to a separate volume if you
really need to, see

http://www.rabbitmq.com/install-rpm.html
http://www.rabbitmq.com/relocate.html

If you publish messages as persistent (stored on disk), you will likely benefit from flash storage
at high message rates. If not, it won't make much difference.
