Increasingly skeptical of M4 being Oracle
The new Hot Chips program, posted a few days ago, mentions a 16-core "SPARC64 X" for the "next-generation UNIX servers." This would seem to imply that either M4 is actually a Fujitsu processor, or that Fujitsu's going to keep making its own CPU's for its own Solaris servers without Oracle on board.
