In a recent test, Nautilus says the water being returned to the bay was was just 4 degrees warmer than the intake temperature. Their design goal is to minimize the temperature differential to avoid any environmental impact. Having said that, the proof-of-concept test was with 5 racks of gear, rather than an 8 megawatt data center. They believe the design works, but it hasn't yet been tested at scale.
The effort to gain acceptance for DC distribution in data centers is being helped by a series of investments by ABB, and the growth of the EMerge Alliance, which is trying to unify DC proponents around a 380V standard. The challenge for DC is that customers don't ask for it, meaning multi-tenant facilities aren't likely to offer it.
Also, Schneider says it is "not aware of any data centers moving off of their established, traditional power distribution to DC." In fact, NTT has at least five DC data centers in Japan, and ABB is backing a DC distribution project at a Swiss hosting company. In the US, there are numerous sites testing DC power, which is widely used in telecom infrastructure.
The federal data center consolidation effort began early in the Obama administration. After nearly a year of planning, the effort kicked off in March 2010. Many of these older data centers predate the Bush administration. Plenty of blame to go around, but Obama and his IT team have been the first to attempt to tackle a consolidation effort.
There are reports that Google has been testing servers using low-power many-core servers from Tilera and Quanta. Facebook is also test-driving Tilera chips and seeing promising results when using them on key-value pair apps like memcached. When you have 900,000 servers, you get plenty of attention from processor and server vendors.
As others have noted, there are many good examples of data center reusing waste heat. Here's a list of examples of server heat being recaptured to warm homes, offices, greenhouses and even swimming pools. This is common enough that The Green Grid recently released guidelines on the best way to integrate heat recapture in key efficiency metrics like PUE (Power Usage Effectiveness).
Here are some images of the system, which currently uses 672 cabinets and uses about 10 megawatts of power. The K system is more powerful than the next 5 systems combined. It's a big-ass system.
Data Center Knowledge has a photo feature with a bunch of images of the facility in Quincy and the container modules being assembled. You can see all the servers they pack into them.
Netcraft has been tracking the shifts in Wikileaks' infrastructure, and notes today that one of its post-Amazon hosts is Swedish ISP Bahnhof Internet, which operates the "James Bond Villain" data center housed in a nuke-proof bunker 100 feet beneath Stockholm.
Comcast says the issue with Level 3 is a peering dispute and says it "offered Level 3 the same terms it offers to Level 3s CDN competitors for the same traffic." The issue seems to be that the Level 3's addition of Netflix as a customer may have altered the balance of the traffic exchange between Level 3 and Comcast. In other words, Comcast says the volume of traffic is the issue, while Level 3 says the type of traffic is the issue.
There are several ways that variable wind generation loads can present challenges. Texas, which has a large concentration of wind generation facilities, experienced an incident in early 2008 in which a sudden dropoff in wind triggered a grid emergency. A cold front came through, generation dipped, and utilities had to implement power shaving strategies, primarily reducing service to large customers who trade lower rates by being "interruptible."
Except that by the time Sun "invented" the Blackbox, Google had already secretly built an entire data center filled with data center containers. And applied for the patent on the concept, which it got.
The concept HP described in an academic paper is not new, and is already being built into a UK data center that has won awards for its approach. The Infinity ONE data center in East Anglia, England is working with a local farming co-op to use cow manure to power a combined heat and power (CHP) plant that will provide electricity for the data halls. The data center is already operational (using utility power) and expects to integrate the poop power sometime this year.
From the McAfee writeup: "So far the attacks we've seen using this vector have been focused on Internet Explorer 6." The stupid but obvious question: why are people at these companies using IE6?
The increased sales of warranties are driven by the difficulties faced by electronics retailers. In an environment where there are fewer customers, stores look to increase the revenue per customer, and the easiest way to do that it to pressure sales associates to sell more warranties. It's an emotional decision... the conversation takes place at the checkout counter, and rarely in a context where the shopper can take time to make a reasoned, fact-based decision. The desire to get extended life out of the product is no doubt providing an incremental sales boost. But the upsell is getting more forceful, and that's certainly about the economic concerns about the retailer, not the consumer.
John Savageau, who has been an executive with a number of hosting and colo companies, recently blogged about Questions Data Center Operators Don't Want You to Ask, which some colo shoppers may find useful. It looks at issues for colo centers in mixed-use buildings and the merits of SAS70 certifications, which are often a key marketing point for facility operators.
This is all about Dell buying service revenues in health care and government, two areas that are getting s huge boost from the Obama stimulus package. In today's conference call, Perot Systems said it gets 48 percent of its revenue from the healthcare sector, and 25 percent from government. That's a strong footprint in two key growth areas, which is why Dell is paying a 65 percent premium to Friday's share price for Perot.
An obvious brand extension: Hey, Patrick Stewart and Hugh Jackman can both sing, right?
Kidding aside, Disney execs would be well-served to remember that "with great power, comes great responsibility."

When it comes to aggression versus servers, you can't beat the Gallery of Exploding Servers. Some serious mayhem inflicted upon hardware.

The YouTube staff now says the downtime was due to a technical error. That really narrows it down.
