CCM clustering over WAN

[nkariyawasam]

Does CCM supports clustering over WAN link ? If so, what is the rough bandwidth requirement between the servers for about 800 user deployment ?

Yes it does. The latency cannot exceed 40 ms, and you will need about 900 kbps primarly for SQL replication. Take a look at the SRND document for details www.cisco.com/go/srnd
