Yup, Exadata uses OFED

I checked out this video today, with OF's Executive Director, Bill Boas, speaking to the Lustre Users Group 2009.
He mentions RDS favorably a number of times. One thing that he would probably also like me to mention is that yes, Oracle's Exadata product (you know, the one with all the ads in The Economist, The Week, and The WSJ) is based on InfiniBand and OpenFabrics' software, OFED. Perhaps OFED has succeeded in its mission so well, and become so ubiquitous, that it may have become one of those parts of your system that "just works", and gets no love.
I think it would be cool for Larry Ellison to name-check OFED, IB, and RDS as ingredients in the Exadata special sauce... but I don't know if he or the ads even mention it runs Linux? Or GNU software? Or OEL's lineage from code by a certain North American Enterprise Linux vendor? I'm pretty sure he does mention the database software, though. :)
So, what can you do? People working on HPC and high-speed networking already know who OpenFabrics is, or at least about OFED. Even as converged Ethernet and IBoE bring RDMA to a wider audience, I have my doubts whether OFED will become a well-known name. It may simply have to count being relied-upon by a growing, happy userbase as its success.
