Good Afternoon,

We are in the process of implementing Exchange 2007 (on Server 2008
Enterprise OS).  After some research, we've decided to cluster our 2 mailbox
servers using CCR with the data and logs stored on direct attached storage
(DAS), as per the technote linked below:

http://technet.microsoft.com/en-us/library/cc500980.aspx

There will be 2 clustered mailbox servers, each with it's own direct
attached storage.  The passive node will be kept in sync via CCR's
transaction log shipping.  When we vaildate this cluster, it passes except
that it gives us some warnings regarding storage, since there isn't any
"shared" storage per se.  This is expected since there really isn't any
"shared" storage, but rather each server has it's own storage, and the
transaction log shipping keeps them in sync.

My concern is that in a Windows Server 2008 Failover Clustering Architecture
Overview document, it states

"When you run a validate, some tests may not pass, but clustering may still
install and function.  For example, not conforming to a cluster configuration
best practice (such as having only one network interface card) will raise a
warning rather than an error, but the cluster would function.  However,
passing Validate is the standard for support for clusters in Windows Server
2008.  If a cluster does not pass Validate, it is not supported by Microsoft."

Does this mean that even though we are using a configuration that is
supported (and even used!) by Microsoft, we won't be able to get support
because of the storage warnings that occur when we validate the cluster?

Any clarification would be greatly appreciated.

Thank you,
