Automotive Ethernet makes the NY Times

at least, an online blog of it.

BMW Ethernet Presentation

As a followup to a previous post, BMW presented at Freescale’s Technology Forum 2010 Ethernet for Automotive Applications an overview on what they are doing for automotive Ethernet. By 2015, there will be 9 million RSE (rear seat entertainment), 5 million In-car TV, and more than 15 million parking aids installed in cars. For good or for bad, there is one standard for wire transport from metro, to cell phone backhaul, to your desk IP phone. It’s called Ethernet. There’s one set of protocols for Ethernet: internet protocol suite (TCP/IP and UDP)*. Do you want to re-use and adapt all of the Ethernet technology available for low cost and no royalties, or re-create the Ethernet ecosystem in an expensive, royalty-based closed system that includes an ad-hoc implementation of Ethernet?

*FCoE proponents may disagree with this, but just wait 5 years.

Special Purpose Hardware for the Web

Ashlee Vance wrote an interesting article, Big Web Operations Turn to Tiny Chips describing some new startups using netbook chips as the CPU in webservers. SeaMicro virtualizes the I/O. Several companies have have designed I/O virtualization producs such as Xsigo Systems, Next IO, and Vertensys but these products are top of rack. SeaMicro points out that only 1/3 of the total power consumption of a server is used by the CPU. Virtualization of I/O will help with that. SeaMicro stuffs 512 1.6GHz Atom z530 chips in a 10u chassis.

A search of the careers on their website indicates they are targeting running nginx or apache webservers with MySql. I wonder what 10 systems each with 10 gig Ethernet, solid state storage and dual sockets populated with AMD Phenom II X6 1090T CPUs which have a passmark of 6,527 would compare to SeaMicro’s 512 z530s with a passmark of 299 with 64 gigabit ethernet ports. It will be interesting to see the benchmarks.
