Hi there.
We are going to implement the Cisco ACI Multi-Site solution between two sites. One of the main components of Multi-site is MSO (ACI Multi-Site orchestrator) which I found the "ACI-MSITE-VAPPL" part number for it. Based on the Cisco white paper given for ACI Multi-Site, three MSO nodes are clustered together in an active/active fashion. does it mean I need to order 3 number of ACI-MSITE-VAPPL?? or like APIC it has own clustered part numbers?
