My company will be migrating from Exchange2003 to 2007, and we purchased two new servers to do so. We have the following newhardware: PowerEdge 2950 III - 2x73GB 15krpm for OS, and 6x146 10k rpm for Data -NEW PowerEdge 2950 III - 2x73GB 15krpm for OS, and 6x146 10k rpm for Data -NEW PowerEdge SC1435 (I am thinking this would make a good Edge Transport) -OLD and will be rebuiltSAN - 5x300GB 15k rpm Fiber Drives (plus VMWare capabilities) -Purchased for Exchange 2007 setup We wanted to enable clustering to prevent what happened to us with Exchange 2003 - we had a catastrophic database failure andour email services were down for a week. From what I can tell, you need three servers, not just two for a clustered setup. We do have VMWare, and a SAN with 5x300GB 15k rpm fiber drives for the main 2007 Exchange database. Suggestions for setup? I am not quite sure what flavor of clustering we can do with just twonewphysical servers, and VMWare/SAN. I know turning a server into an activecluster node only replicates the Inbox role correct? So, redundancy would be needed with the hub transport. What good is having a redundant inbox if there isn't any service available to push the email around.

Cody,If you read the support guidelines from Microsoft you can read that it isn't supported to run Exchange 2007 in a virtualized environment. So I personally do not recommand it in production environments. In test environments you can try it.I recommand to setup a CCR cluster, you can follow the this article on MSExchange.org if you decide to do this then you need to install the HUB Transport server on another server because it can't be installed on the cluster. With that said I personally recommend to buy another server to use NLB for the HUB transport server so this one is also HA.Johan
