Must-read piece on Massively Scalable Data Center networking

Like Ivan Pepelnjak, I agree that the must-read piece of the moment is Brad Hedlund’s Emergence of the Massively Scalable Data Center. Yes, it’s more about the questions than the answers, but even that’s a step forward. And as a bonus, this led to me browsing Ivan’s blog, where I came across this excellent piece on how we got into the present L2 v. L3 mess (including the impact of what Ivan calls “the elephant in the data center”).
