Hi 3Par users,
I just wanted to let you know that OpenSVC published a tutorial showing how to build metroclusters / geoclusters / stretched hypervisors with HP 3Par Storage & Remote Copy. This solution is open source free software, and support multiple unix variants.
If you have any further inquiries, I would be glad to assist you.
