Exchange Servers Admin >> exchange clustering

I am looking into building an exchange 2003 2 node cluster.
We have had a SAN installed with 500 gig raid 5 partition for exchange
databases and a seperate raid 1, 200 gig partition for our exchange logs.

I am a little confused reading the documentation:

http://www.hide-link.com/ ;en-us;301600

It says you should have a MSDTC cluster group with it's own physical disks.
Can this group use the same physical disks that will contain my exchange logs
or does it need seperate disks?

The use of a SAN pretty much takes the whole "physical disks" thing in
those articles away. You'll need to present a separate LUN so that
Windows thinks it's a separate disk but whether it is or not is
entirely a different case. Obviously it would be a gross waste of disk
to assign something dedicated and the MSDTC doesn't actually need to
be separate anyway. There are articles with differing advice but
neither method is prescriptive so they're not to be classed as
necessarily contradictory.

Assign a LUN from the raid1 set if you do want to keep them completely
separate.
