[r.horvath]

HI,

Has anyone actually done or can help regards Clustering over the IP WAN using remote failover depoyment model?

I am looking at deploying a publisher and subscriber at one site and 2 remote subscribers at another. The question is as follows:

Do I require to double up on the IPWAN bandwidth between sites if I depoly the 2 remote subscribers as above?

Thanks in advance

Every 10,000 busy hour call attempts (BHCA) in the cluster requires a minimum of 900 kbps of bandwidth for Intracluster Communication Signaling, with no more than 40ms round trip time allowed between any 2 servers in the cluster.
