From an architectural point of view I think that the DCB/CEE standards are absolutely key to the future. Yes we all know about FCoE (there would be no viable FCoE without DCB/CEE and in particular Priority Based Flow Control) but I think that the emerging DCB/CEE standards will create a unified fabric that will prove a new foundation for all kinds of new innovative technologies. We already hearing about the benefits of extending these features to the likes of iSCSI and the potential of UDP on a lossless fabric...... (assuming assigned a lossless lane). Looks to me like data center networking is changing right now. Rack Area Networking is a topic that seems to be coming up in more and more conversations..... Thinking a little more outside of the box, PCI-SIG MR-IOV standards could potentially bring HUGE changes to Top of Rack interconnection architecture. This kind of stuff keeps me up at night, well not really but you know what I mean ;-) Of course in 5 years time the pendulum might be swinging in the opposite direction :-D Nigel Hi Douglas,

I think in 5 years, server virtualization will be seen as an architectural bottleneck instead of an architectural enabler. I’ll throw a crazy idea out.

I know I was caught flat-footed a few times, othertimes I jumped too quickly. A few times I got it right (those were the rarest) but I learned from all of them...

While we would like to think that the new approaches would eclipse the old, there is usually a period of coexistence... this is, in fact, a good thing since, as you point out, "embracing a fickle trend too quickly can be just as painful".... Thanks, LeitM P.S. Typo in the sentence (part reproduced below) - should it be "deliver" instead of "delivery"? Should it be "shifts" instead of "shift"? delivery short-term value creation, while building towards a longer-term vision that enables IT to reinvent itself and infrastructure to transcend generational shift. Doug,

When to jump is a classic issue. I remember joining a company that had just deployed 1st generation Kalpanas into the core of their network. What a disaster. But there was something to what all of those companies were doing. On the other hand, the annals of start-ups are littered with technologies that were not worth jumping to at all. Clearly cloud is one that is here to stay, but the big lie is that it is new. Out there, many people call it by its true name: outsourcing.
