Funny you mentioned IPF. Last year the weather channel bought Opteron servers for DBMS appplications. Guess what 2P and 4P Linux servers they are now buying from HP to run DBMS, web, file, and print serving applications etc.
And to think of all the people on this forum who told me that IPF couldn't possibly compete against Opteron in the 2P/4P entry level server segment because of its pricing. Its not like HP couldn't have sold them some decent 2P and 4P Opteron servers *if* they had wanted them, ROFL.
