Throw another process log in the data furnace, darling

Paul Raven @ 27-07-2011

Via SlashDot, an intriguing idea comes a-squirming out of Microsoft’s Research wing: the data furnace. You know how your computer hardware chucks out a whole lot of heat as a waste product? Well, imagine how much a datacentre has to cope with. So why not put that waste heat to good use, and use it to heat people’s homes?

The genius of this idea is that Data Furnaces would be provided by companies that already maintain big cloud presences. In exchange for providing power to the rack, home and office owners will get free heat and hot water — and as an added bonus, these cloud service providers would get a fleet of mini urban data centers that can provide ultra-low-latency services to nearby web surfers. Of course the electricity cost would be substantial — especially in residential areas — but even so, the research paper estimates that, all things considered, between $280 and $324 can be saved per year, out of the $400 it costs to keep a server powered and connected in a standard data center. From the inverse point of view, heating accounts for 6% of the total US energy consumption — and by piggybacking on just half of that energy, the IT industry could double in size without increasing its power footprint.

You will have, of course, already thought of the most obvious objection or snag:

The main problem with Data Furnaces, of course, is physical security. Data centers are generally secure installations with very restricted access — which is fair enough, when you consider the volume and sensitivity of the data stored by companies like Facebook and Google. The Microsoft Research paper points out that sensor networks can warn administrators if physical security is breached, and whole-scale encryption of the data on the servers would ameliorate many other issues. The other issue is server management — home owners won’t want bearded techies knocking on their door every time a server needs a reboot — but for the most part, almost everything can now be managed remotely.

An interesting idea, certainly, but one that still depends on the extant hierarchical model of CPU/storage/bandwidth distribution. Better still (at least for this anarchist) would be for every home to have its own datacentre, with multiple redundant backups stored across fragments of other HDDs on other machines in a torrent-like fashion; flops and bytes are already arguably basic utilities for life (for the more privileged among us, at least), and are unlikely to become less essential to us barring some sort of existential-risk scale catastrophe… so the ubiquitous home server becomes as inevitable as the microwave oven. Sure, that model’s not without its risk scenarios, but it devolves responsibility for (and management of) said risk to the end user, removing it from the corporation or government. Of course, not everyone sees that degree of personal responsibility for risk as a net social good… 🙂

More obviously still, though, the flaw to the data furnace plan is that it overlooks the most logical response to waste heat, namely the development of more efficient computing hardware… after all, we have way more flops and bytes than the average domestic application really demands by this point… so instead of chasing BiggerBetterFasterMore, we could maybe chase SmallerCoolerLighterLess.


Wind farm, server farm

Paul Raven @ 22-07-2009

wind turbinesServer farms use a whole lot of power, and with the price of energy likely to start skyrocketing again before too long, canny businesses will be looking for a way to keep a cap on the costs of running their hardware. Enter Texas firm Baryonyx, which intends initially to build server farms powered primarily by renewable energy sources like wind power… but that’s just the start.

Baryonyx plans to build a 28,000 square foot data center in Stratford, which will be powered by 100 wind turbines built on the adjacent land that will generate up to 150 megawatts of power. Each of the turbines will be able to generate up to 3.3 megawatts of power. Capacity not needed by the data center will be sold to local utilities. Baryonyx said it will take about 3 years to reach the operational phase for the wind-powered data center.

The second phase is the offshore wind farms, which will feature up to 450 wind turbines, which are each 300 feet tall and capable of generating 6 megawatts of power. Baryonyx was the high bidder in a July 14 lease sale by the Texas General Land Office. Baryonyx will pay a “nominal fee” to lease the two offshore areas for wind development.

Now there’s a sound business model; sell a more affordable solution to the desperate-for-efficiency first, and then sit back as rising oil prices ensure that your target market just keeps growing… [via SlashDot; image by jesse.millan]
