Japan's Underground Datacenter - System News - 0 views

data center container locations sun-msft cloud

shared by Paul Merrell on 11 Jul 08 - Cached
  • 00 meters under the ground in Japan, Sun along with ten other IT firms are building a datacenter. The datacenter is located at such a low depth to take advantage of the cooler air as a means of bringing the 40% of energy usage, for cooling, down a few notches. The datacenter will also be reluctant to Japan’s earthquake potential by being built on the solid bedrock floor of the crater hollowed out for the project.
  • In the underground pictures it is clear that the Sun Modular Datacenter 20 is going to be a successful format for the datacenter because it is self contained and there is an abundant resource of ground water in the cave for a cooling system. The data center will be used by government agencies, it will serve as a service center for IT clients, and it will be used by businesses.
  • The Sun MD 20 Sun is included the design of this datacenter. In the earthquake analysis, the prototype was placed on a large shake table in California, and put through a simulation of the Northridge earthquake of 1993. The results were very conclusive. The location of Japan’s underground datacenter is still undisclosed. More Information

  • To run Sun’s award-winning data centers, a modular design containing many "pods" was implemented to save power and time. The modular design aids the building of any sized datacenter. Inside of each pod, there are 24 racks. Each of these 24 racks has a common cooling system as does every other modular building block. The number of pods is limited by the size of the datacenters. Large and small datacenters can benefit from using the pod approach. The module design makes it easy to configure a datacenter to meet a client's requirements. As the datacenter grows over time, adding pods is convenient. The module and pod designs make it easy to adapt to new technology such as blade servers. Some of the ways that Sun’s datacenter modules are designed with the future in mind are as follows:

    This page seems to be the hub for information about the Sun containerized data centers. I've highlighted links as well as text, but not all the text on the page. Info gathered in the process of surfing the linked pages: [i] the 3x24 data switch page recomends redundant Solaris instances; [ii] x64 blade servers are the design target; [iii] there is specific mention of other Sun-managed data centers being erected in Indiana and in Bangalore, India; [iv] the whiff is that Sun might not only be supplying the data centers for the Microsoft cloud but also managing them; and [v] the visual tour is very impressive; clearly some very brilliant people put a lot of hard and creative work into this.

Siding with HTML over XHTML, My Decision to Switch - Monday By Noon - 0 views

  • Publishing content on the Web is in no way limited to professional developers or designers, much of the reason the net is so active is because anyone can make a website. Sure, we (as knowledgeable professionals or hobbyists) all hope to make the Web a better place by doing our part in publishing documents with semantically rich, valid markup, but the reality is that those documents are rare. It’s important to keep in mind the true nature of the Internet; an open platform for information sharing.
  • XHTML2 has some very good ideas that I hope can become part of the web. However, it’s unrealistic to think that all web authors will switch to an XML-based syntax which demands that browsers stop processing the document on the first error. XML’s draconian policy was an attempt to clean up the web. This was done around 1996 when lots of invalid content entered the web. CSS took a different approach: instead of demanding that content isn’t processed, we defined rules for how to handle the undefined. It’s called “forward-compatible parsing” and means we can add new constructs without breaking the old. So, I don’t think XHTML is a realistic option for the masses. HTML 5 is it.

      Great quote from CSS expert Hakon Wium Lie.
  • @marbux: Of course i disagree with your interop assessment, but I wondered how it is that you’re missing the point. I think you confuse web applications with legacy desktop – client/server application model. And that confusion leads to the mistake of trying to transfer the desktop document model to one that could adequately service advancing web applications.

    A CMS expert argues for HTML over XHTML, explaining his reasons for switching. Excellent read! He nails the basics. for similar reasons, we moved from ODF to ePUB and then to CDf and finally to the advanced WebKit document model, where wikiWORD will make it's stand.

    See also my comment on the same web page that explains why HTML 5 is NOT it for document exchange between web editing applications. .

    Response to marbux supporting the WebKit layout/document model. Marbux argues that HTML5 is not interoperable, and CSS2 near useless. HTML5 fails regarding the the interop web appplications need. I respond by arguing that the only way to look at web applications is to consider that the browser layout engine is the web application layout engine! Web applications are actually written to the browser layout/document model, OR, to take advantage of browser plug-in capabilities. The interoperability marbux seeks is tied directly to the browser layout engine. In this context, the web format is simply a reflection of that layout engine. If there's an interop problem, it comes from browser madness differentials. The good news is that there are all kinds of efforts to close the browser gap: including WHATWG - HTML5, CSS3, W3C DOM, JavaScript Libraries, Google GWT (Java to JavaScript), Yahoo GUI, and the my favorite; WebKit. The bad news is that the clock is ticking. Microsoft has pulled the trigger and the great migration of MSOffice client/server systems to the MS WebSTack-Mesh architecture has begun. Key to this transition are the WPF-.NET proprietary formats, protocols and interfaces such as XAML, Silverlight, LINQ, and Smart Tags. new business processes are being written, and old legacy desktop bound processes are being transitioned to this emerging platform. The fight for the Open Web is on, with Microsoft threatening to transtion their entire business desktop monopoly to a Web platfomr they own. ~ge~
