After re-reading your original request, You could use two separate controllers if you virtualize the entire setup. You still will need two Open-e Licenses.
you could go for replication within a single system - "2010.11 Open-E DSS Asynchronous Data Replication within a System" - http://documents.open-e.com/Open-E_D...n_a_System.pdf remember - you've got only one mother-board :-)
