how to implement CM Cluster

[juanmojica]

I have a CM 4.01 runing on a server, in order to have a fault tolerance, we want to install a suscriber CM, is this a CM cluster or we have to have a Cluster using the operating system?

Any link to a documentation will be apreciated.

Thanks

Installing a subscriber CM is indeed the same as creating a cluster. Currently you can have up to 7 CM servers in a cluster, with 1 being the pub and 6 being subscribers. Clustering is fairly bandwidth intensive and usually the servers should be on the same LAN.

Just to clarify... On the cluster you can have I think around 20 Servers (i.e. CCM Servers, TFTP Servers, Publisher Server, MOH Servers, IPVM Server, etc) ...where 8 of them can run the CCM Service... Usually the PUB doesn't run the CCM service in large environments... so the PUB doesn't count as one of the 8 CCM Servers..
