The Gartner Magic Quadrant for Data Warehouse DBMS Servers, 2006 is out now and available at link. As the report itself says "NCR's Teradata server is the clear leader."
This report is just for the backend server used to house the data warehouse. And, of course, you never buy just that. You would also need to be comfortable with the DBMS possibilities for that server. For example, Teradata DBMS on Teradata. Initial cost, lack of openness and lack of low-end MPP mean that their placement does not directly translate to market share.
Interestingly, at the other end of the Ability to Execute spectrum is Netezza, which should gain acceptance as their customer base grows and Linux gains acceptance, both of which are happening.
These are the only 2 on the list where a specific and single DBMS is tied to the platform. Most companies start with the DBMS in their selection process of DW platform.
