Appreciate if anyone can breif what is a mega cluster in CUCM. I recently came to know that mega cluster supports more than 8 call processing servers in a cluster with COW nodes
CUCM supercluster can support upto 16 call processing servers, 1 publisher, 2 TFTP servers, and up to 9 media resources servers. It enhanced the system capacity than normal deployment (30k phones). The development on CUCM Supercluster should go for Cisco BU approval via the Cisco Account Team (SE or AM).

What are the versions of UCM software that support megaclusters? Is there any clustering over the WAN requirements with megaclusters as well? For example, could I have all 16 subscribers at different sites clustered across the WAN?
Cisco Megacluster is currently supported on Cisco Unified Communications Manager 6.1 and 7.1. No Megacluster support is planned for 6.0, 7.0, and 8.0.
Current plans are to support megacluster in 8.5 for both MCS Servers and also on the UCS platform.
Clustering over the WAN is supported, but the guidelines found in the CUCM7.1 SRND will strictly be enforced.
I can not get the doc from this link
I would ask Wade Hamblin directly.
That document is located in the Cisco Partner Community, which is accessible only to Cisco partners. Have you reviewed this information about CUCM and mega clusters?
