I am trying to do a 2008 CCR cluster to get ready for an exchange 2007 installation. Is there an article written that shows the steps to setup MNS? When I go to the quorum config sceen and choose node majority, it was already defaulted to that, and says it doesn't see any disks even though both nodes have a d:\ of 500 gigs. Am I doing something wrong? Thanks for the explanation of all of this. I am trying to do a 2008 CCR cluster to get ready for an exchange 2007 installation.

Should we try to keep a 1:1 A:P ratio? I can have as much a 7:1 . Is the one passive able to act as a failover for all the actives? Even though they contain different data stores?

Exchange 2007 CCR clustering operates on the principle that each node has its own storage, and the log files are replicated between the master and secondary node via a wan link - where they are replayed into the secondary nodes database. The cluster itself in CCR is configured as a MNS where, again a copy of the Quorum database is stored on each node and updated via the WAN.

I'm a little confused though, could you explain what the differences is between having a normal say Exchange 2003 Cluster (2 Node) and then having the added feature of CCR? Exchange Cluster can be already split into two seperate data centres? Confused here. Ray Hi,
Very good representation.

Exchange Cluster can be already split into two seperate data centres?

Confused here.

Ideally, I would like to require only on server for exchange redundancy at the DR remote site. At the primary site, we have a SCC cluster, and additional servers as the CAS/HUB role.
