For those who can't be bothered to sort thru the clutter/profanity on Yahoo message board , here's a worthwhile repost: Inifiband based networking gear by: viangio 12/11/99 11:08 pm Msg: 22009 of 22016 The LAN networking types are there because Infiniband is "Infinite bandwidth" for I/O. It's not just I/O bus replacement in servers. It's classic bus replacement anywhere. The IP router folks all have big wide buses in their IP routers. The Inifiniband idea is throw the bus away and replace it with a fabric. The fabric can scale as much as you want simply by adding links and little switching chips. So in a big IP router for example you could have line cards that externalise to standard interfaces such as Ethernet, ATM etc. But internally, the LAN packet router is sending packets over a fabric of Infiniband links. If I want to increase the capacity of my IP router I can add more line cards while also scaling the internal fabric to match. I cannot do that with today's LAN routers and the reason is the internal bus won't scale. Cisco and others have all played with fabric based router architectures at one time or another. They are common in parallel super computers. But now, the Inifiniband effort is set to make this a high volume off the shelf technology. I'll be able to build application specific hardware - whether it be a new kind of server (CPUs, memory and disks) or a new kind of IP router (one CPU and loads of LAN interface line cards) or even a big graphics engine (lots of pixel renderers and distributed frame buffers). So the answer is Nortel, Lucent, 3Com and Cisco are all there because Infiniband is an architecture that allows them to innovate, design and build next generation communication equipment. Dell, Compaq, HP, IBM and Sun are all there because Infiniband is an architecture that allows them to build application specific scalable servers for less than today's models. Infiniband is a totally revolutionary architecture. It's been coming for a long time and a number of prior experiments had to fail to get this far. Classic servers and what they attach to will change in drastic ways. One can imagine for example; an Inifiniband based server and LAN IP router in the same cabinet - with all the neurons attached to the fabric. Hardware for an integrated application engine - where the application is serving Web pages, video feeds, voice mail, eCommerce credit card transactions etc. etc. It's an architecture for a totally connected planet. Phew. The Ancor deal cannot be understated - Ancor's switch ASICs could show up in Cisco equipment. Can you imagine.... BTW, business school CEOs don't get this. Technology leaders do. Maybe this explains some of the rhetoric lately. Posted as a reply to: Msg 22005 by jfieb View Replies to this Message
