Win2008 Quorum Disk on CCR

Kevin Zhang · Joined: 27 Feb 2008 Posts: 2

I am planning on Exchange 2007 SP1 on Windows 2008 with CCR. In Windows
2003 cluster, FWS can be located in a network share. In Windows 2008, it has
been changed and it has been called "witness disk or quorum disk". My
questions are

(1) Can I still use a network share for "witness disk"?
(2) I need two external shared storage in order to run EX2007 SP1. If I use
one of the shared external storage for "witness disk", do I need to have
'witness disk" on the other shared storage space?

Thanks in advance.

Kevin

Use Node and File Share Majority (for clusters with special configurations)This
is the equivalent of Majority Node Set with File Share Witness in Windows
Server 2003

For CCR on Windows Server 2008, you want to use a Node and File Share
Majority quorum. See
http://technet.microsoft.com/en-us/library/bb676571(EXCHG.80).aspx.

CCR does not use any shared storage (either for the quorum, or for
Exchange). You need storage that is connected to each node and not managed
by the cluster.

Thanks for the answer. Node and File Share Majority Quorum is the way to
go in Windows 2008. How much data are hold on quorum disk? Does CCR keeps a
copy of qurum data on other external storage too? In another words, is
quorum disk mirrored on the other storage. Sorry I am new to this topic.
