This is sorta a double-post, but I wanted to make sure the my question didn't get buried by another.

I'm having issues with MSDTC install on Windows 2003 EE. The docs say that MSDTC needs it's own IP, Disks, etc.
How large of a disk does it need? 1GB? 20GB??
Can it be shared with another disk array, say the RAID 1 that contains SQL TX Logs?

Thanks!
Michael

1GB is plenty

You need a separate drive letter for the cluster group. If you carve off a LUN from the underlying RAID in your shared storage that also holds the LUN for your TLOGS, that is fine. You need to make sure that the 1GB drive for MSDTC has it's own drive letter, and that that drive letter is different than the one you use for your TLOGS.

This really applies to any drives used in MSCS. You cannot share the same drive letter across multiple cluster groups.
