Hewlett-Packard dropped out of the eight-socket x86 business a couple of years ago because it couldn't do a Xeon box without doing its own chipset and it had stopped making its own chipsets. It threw itself into two- and four-socket multi-cores instead, which didn't have application scalability problems. And it cleaned up on blades and four-socket machines. It's supposed to own 46% of the four-socket market and 48% of blades.
