Sorry if I am double posting but I got a reply saying that my email had been rejected. Good morning to all, I have a few questions about an Exchange 2003 Cluster. We are looking into upgrading our current Exchange 5.5 to Exchange 2003. Right now we only have one server, one site. For redundancy purposes we are considering an Active/Passive cluster. Could you please tell me a best practices for setting this up? How will the fail over occur if the active node goes down? I am planning to have the log files reside on the server itself and have a Fiber Raid Array for the DBs. If the primary node fails how will the stand by node handle the logs? Thanks in advance for any information you can provide. Juan
