SQL Cluster + DMS cluster in the same machines

System

Hi all, I have a new Worksite impletation in which the customer wants to reuse some machines, my question if anybody has implemented a SQL Active/Passive cluster in the 2 same machines as the DMS servers, using Interwoven clustering services.

I have small clients whose has only one server for SQL server and DMS serverand it works without problems, however could it be possible using clustering for 2...

If anybody has implemented this architecture or have information about why not it would be a good choice (problems,etc..) I would be very thank of getting your experiences.

Regards
Javi
