Multiple Enterprise Servers supported with StruxureWare Building Operation?

Issue

Are multiple Enterprise Servers in same system/site supported with StruxureWare Building Operation? 

Product Line

SmartStruxure Solution

Environment

StruxureWare Building Operation site (generally a larger site)

Cause

When will two or more Enterprise Servers be connected together to form a unique system?

Resolution

Multiple Enterprise Servers are not currently in the roadmap (meaning >= 2014). Multiple Automation Servers clearly is.
