Google probably didn't want Sun's hardware. They have the dubious honor of having some of the largest processor design teams out there, and yet some of the slowest processors in every generation.
I read an article about how much the DB2 folks liked Sparcs, and would MUCH rather convince their customers to buy Sun boxes than IBM, Itanium, or x86 boxes. The reason? The DB2 group charges a per-CPU license fee, similar in magnitude to Oracle's. On a POWER machine they would typically sell 4-8 licenses. On Itanium and x86, they might get to 32.
