Why Model? Increase Trust in The System

I”ve just had a day of intense modeling conversation followed up the next day a lunch meeting with an old friend who just left Microsoft.  We worked together at Apple, and ran into other during years at Microsoft.  Coincidentally, we saw each other a week after he left while he was on a charity holiday run.  He left Microsoft after 14 years and I did too. 

Given his recent departure and process of decompressing from 14 years at Microsoft I asked if he had reached an epiphany.  He hadn’t yet, but I did.

There are many reasons why you want to create abstract models of complex systems.

Scientific modelling is the process of generating abstract, conceptual, graphical and or mathematical models. Science offers a growing collection of methods, techniques and theory about all kinds of specialized scientific modelling.

Modeling is an essential and inseparable part of all scientific activity, and many scientific disciplines have their own ideas about specific types of modeling. There is little general theory about scientific modeling, offered by the philosophy of science, systems theory, and new fields like knowledge visualization.

And, I have had fun discussing models with executives like Thetus’s Danielle Forsyth and Skanska’s Jakob Carnemark.  We all see the benefit, but how do you get others to understand why modeling.

Modeling enables Trust of a technical solution.

For a trustful and friendly use of technology, the user must be able to have a clear mental model of its use and functioning (way of working), being it partial, superficial and even wrong, but at the same time sufficient for having precise expectations and for knowing how and what to do, i.e. sufficient for reducing uncertainty and perceiving safety and reliability.

So, why model the data center? It increases trust in the data center system including its users. Higher trusts promotes knowledge sharing.

It is clear how trust is a precondition for knowledge sharing and a result of it or, more precisely, that trust is a mediator, a catalyst of the process: it is a mental and interpersonal (cognitive, dispositional, and relational) precise condition for the two crucial steps in the organisational flow of knowledge.

The relationship between trust and knowledge sharing is circular: in order to trust Y, X must either have information about Y, helping him to evaluate Y's trustworthiness, or having knowledge in common with him that encourages the establishment of a trust relationship so as values sharing; on the other hand, in order to share knowledge, it is necessary to have a trust relation or atmosphere.

While caring of making knowledge capital explicit and circulating, an organisation should care of what are the beliefs of the actors about the knowledge itself, about the organisation values, authority, infrastructure, and about each-others, and what they expect and feel on the basis of such beliefs. In knowledge management organisations should monitor and build the right expectations in their members. Knowledge management entails a cognitive, affective, and structural "trust management" in organisations.

I’ve always done business assuming trust of the other party to create partnerships. I hadn’t thought about it as a separate property that indicates the health of the a system.  Modeling if used right can increase trust of the modeling systems.

Green Data Center Driven by Cost, Symantec Study

Symantec published its 2008 Data center report as a press release.

Symantec’s 2008 State of the Data Center Report Reveals Managers Pressured to “Do More with Less”
Struggling with adequate staffing, data center managers worldwide are compelled to deliver better service levels to meet increasing demands while reducing costs

CUPERTINO, Calif. – Jan. 12, 2009 – Symantec Corp. (Nasdaq: SYMC) today released the findings of its 2008 State of the Data Center report. The second annual study found that data center managers are caught between two conflicting goals – more demanding user expectations and higher levels of performance, yet reducing costs remain the primary objective for the data center. The report also found that data center staffing remains problematic, servers and storage continue to be underutilized and disaster recovery plans are out of date. Finally, the respondents indicated that while they are pursuing green data center initiatives, they are doing so primarily based on cost benefits.

“This research confirms what we are seeing in the field,” said Rob Soderbery, senior vice president of Symantec’s Storage and Availability Management Group. “Attention has turned to initiatives that will drive immediate cost reduction, rather than longer term ROI driven programs.Storage has been a primary focus of these initiatives as the demand for capacity continues to rise, despite economic challenges.”

Green Data Centers are a subject of the study.

Green Data Center Driven by Cost

Continuing the trend first spotted in 2007, the data center’s focus on “being green” was driven by cost issues in 2008 with social responsibility on the rise. The study asked companies why creating a Green Data Center was important to their workplace. Reducing electricity consumption was mentioned by 54 percent, followed by reducing cooling costs (51 percent) and a sense of responsibility to the community (42 percent).

Carbon Cost of Google Search

BBC has a post on the Carbon Cost of Google Search.

'Carbon cost' of Google revealed

The research found a google search produced 7g of carbon dioxide

Two search requests on the internet website Google produce "as much carbon dioxide as boiling a kettle", according to a Harvard University academic.

US physicist Alex Wissner-Gross claims that a typical Google search on a desktop computer produces about 7g CO2.

However, these figures were disputed by Google, who say a typical search produced only 0.2g of carbon dioxide.

A recent study by American research firm Gartner suggested that IT now causes two percent of global emissions.

Dr Wissner-Gross's study claims that two Google searches on a desktop computer produces 14g of CO2, which is the roughly the equivalent of boiling an electric kettle.

Google’s Urs Hoelzle has a response.

Recently, though, others have used much higher estimates, claiming that a typical search uses "half the energy as boiling a kettle of water" and produces 7 grams of CO2. We thought it would be helpful to explain why this number is *many* times too high. Google is fast — a typical search returns results in less than 0.2 seconds. Queries vary in degree of difficulty, but for the average query, the servers it touches each work on it for just a few thousandths of a second. Together with other work performed before your search even starts (such as building the search index) this amounts to 0.0003 kWh of energy per search, or 1 kJ. For comparison, the average adult needs about 8000 kJ a day of energy from food, so a Google search uses just about the same amount of energy that your body burns in ten seconds.

In terms of greenhouse gases, one Google search is equivalent to about 0.2 grams of CO2. The current EU standard for tailpipe emissions calls for 140 grams of CO2 per kilometer driven, but most cars don't reach that level yet. Thus, the average car driven for one kilometer (0.6 miles for those in the U.S.) produces as many greenhouse gases as a thousand Google searches.

We've made great strides to reduce the energy used by our data centers, but we still want clean and affordable sources of electricity for the power that we do use. In 2008 our philanthropic arm, Google.org, invested $45 million in breakthrough clean energy technologies. And last summer, as part of our Renewable Energy Cheaper than Coal initiative (RE<C), we created an internal engineering group dedicated to exploring clean energy.

Stanford Universities Green Data Center Efforts

The Chronicle of Higher Education writes on Stanford Universities green data center efforts. Nothing really new, but nice to see that this issue has made it into a university publication.

Here are some nuggets.

Now the pipes that supply cold water to help keep the servers cool are running at full capacity. The building has trouble taking in the huge amounts of electricity that modern-day servers require. For each dollar spent on computers, the center must spend an equal amount of money to build the power and cooling systems to keep them running.

That cost "has been killing us," says Richard P. Mount, the center's head of scientific computing. The price of storing and processing data, in fact, is hurting every college and university in the country.

In response, some institutions are embracing greener technologies, as much to keep costs down as to help the environment. Stanford is moving toward building a new center that uses outside air instead of chilled water, and it hopes to save just over $3-million per year. "Arguably, this pays for itself," says Phil Reese, the university's faculty and research computing strategist. "There's not many arguments you can give that are that strong." And there are other steps, like consolidating servers and outsourcing services, that are less expensive than building a new facility and reduce data's budget-devouring appetite, computer experts told The Chronicle.

and, here is a summary of the Stanford University Problem.

At Stanford, leaders realized the depth of the problem when plans for every new major building included requests for major computing facilities inside of them, says Mr. Reese. The requests were symptomatic of a larger problem that plagues many institutions, Mr. Reese says: Data centers are spread out across the campus, making it more difficult to ensure that the computing facilities are energy efficient.

In response, the university is moving toward building a new, greener data center off-campus, on the site of the Stanford Linear Accelerator Center. The new data center would serve the university's research needs as well as take over half of the computing capacity of the linear accelerator itself, alleviating some of its infrastructure problems.

The new facility would be twice as energy efficient as the university's current model, Mr. Reese says. The building is designed to take advantage of Northern California's temperate climate, cooling the servers with circulated outside air instead of using chilled water, which is expensive to cool down. It would also expel the hot air given off by the servers, reducing the need for external cooling.

Google, Microsoft, and Amazon are mentioned as outsourcing alternatives.

Some of the most energy-efficient data centers are those run by technology companies like Google and Microsoft and the online retailer Amazon.com, whose profits depend on finding cost-effective ways to store and process data. In the long term, experts expect many colleges to export much of their operations to companies like these to save money and focus on what they know best.

Already, more than 1,000 colleges have signed up for e-mail service through Google or Microsoft, helping those colleges reduce, if only slightly, their need for on-campus data centers. Despite some concerns about student privacy, many colleges have reported that letting professionals take care of e-mail results in significant savings.
