You don’t often get to see the details of a massive data center. The companies that run them tend to keep things pretty quiet, as they view the datacenter as a competitive advantage. Thus, what happens in Google’s datacenters remains mostly a mystery. And yet, it seems that the folks at Weta Digital, famous for providing the computing horsepower behind major Hollywood blockbusters like Lord of the Rings and now Avatar are apparently willing to open up a bit and provide some details about its setup. What struck me as interesting wasn’t so much the hardware specifics, but how they had to switch from the industry standard cooling system of raised floors and air-cooling, because the machines were too close together to get the necessary bandwidth. So, instead, they went with water-cooled racks. Water-cooled data centers have been increasingly common over the past few years (and were typical with many old mainframes), but they’re still a technology that not all data center operators are comfortable with, and which many still think create more problems than they solve. So it’s always interesting to see another one in action.
At the same time, as neat as it is to read about Weta Digital’s massive computing power (which apparently represents one of the 200 largest “super computers”) in the world, I’m still left wondering if the trend — even for amazing movie effects — isn’t moving away from such massive data centers. We’re seeing more and more what can be done on the cheap. And, no, it doesn’t come close to matching the stunning effects found in the blockbuster movies that Weta works on, but it does have all the symptoms of a classic innovator’s dilemma scenario, where the new stuff isn’t “as good” as the old stuff, but is improving at a faster rate, and quickly reaching a point where it’s “good enough” at significantly lower price points.
Given the regular discussions around here concerning movie budgets, where do people think the technology is headed for movie special effects? Will it always be run in giant datacenters, or is there a place for making high quality (even blockbuster-type) films on cheaper hardware?
