I too am investigating this now. I have found that Microsoft NLB is a very good solution. I am sure many others have different thoughts. NLB lets you have up to 32 servers in a cluster. NLB is software based. There is lots of information out there on this. mike >>> [EMAIL PROTECTED] 05/17/01 07:12AM >>> Dear subscribers, please recomend me failover (and load balancing - it is important) solution than can clusterise IIS/ColdFusion servers. Ideal will be analog of ClusterCats. I have tried ClusterCats, but it can't clusterise multi-webservers IIS sites (I want create cluster for several virtual servers, but I dont want to create separate clusters for each virtual server).
