Drew and Woz Meet Andy

As part of our data center networking investigations, we visited with Arastra, Andy Bechtolsheim's latest venture. Andy is one of the most remarkable Silicon Valley fixtures. Not only has he made a lot of money, but along the way he's done some extremely elegant product designs, often doing things simply better than others or doing things that others didn't think could be done (or hadn't thought of). Arastra looks like another winner. It's a 10G switch, and as such is in a category most will never think about but probably use every day. But for those who deal with it directly, it's another really elegant example of Andy's work as the picture below shows:

Arastra's first product is a 48 port 1RU device which is a packaging feat not unlike the Faberge Eggs that the Romanov's were so fond of. Just putting those 48 connectors in a 1U box and still having cooling work is pretty amazing to those practiced in the art. The Arastra switch is also interesting because it's a real deviation from a lot of Andy's early work where he used high complexity custom silicon to create a barrier to others to follow. The Arastra switch has none. Instead it leverages standard parts and creates differentiation through packaging. Steve Wozniak practiced similar art with the Apple II making amazingly clever use of standard parts while others piled on expense to do the same thing. Since hardware isn't the competitive barrier here it must be software. The Arastra switch is designed for the addition of third party software (or the adaptation of existing code into switch functionality). The base operating system of the switch is LINUX and then real-time capabilities are provided by an innovative NetWare like inner environment with a shared state repository providing a lot of the coordination. NetWare was a marvelous software system when Drew Major first created it 20+ years ago in order to make a MHz class PC serve as a high-performance I/O controller (today's multicore CPU's are maybe 5,000 times more powerful). High performance software designers rediscover NetWare regularly. It's sad we don't just teach it in school.
