Today I decided to set up my first Exchange 2003 cluster server using ISCSI to connect to the quorums. I'm also going to do this through Virtual Server so this should be pretty interesting. I'll let you know more when I have this finished. Don't know what ISCSI is yet? There is plenty of information available at http://www.microsoft.com/windowsserversystem/storage/technologies/iscsi/default.mspx.
