LONDON - Demand for energy-thirsty gadgets such as cell phones, iPods, PCs and plasma TVs is undoing efficiency gains elsewhere, the International Energy Agency said on Wednesday.

The Paris-based energy adviser to 28 developed countries urged governments in a report to keep pace with the invention of new consumer devices when crafting efficiency standards, and implored people to make thriftier choices.

The IEA warned that otherwise energy used by household electronic devices could triple by 2030.

Digging into the IEA site found this presentation with this conclusion that was part of the release above.

Note the last statement.

We need strong, robust government policies that ensure greater energy efficiency.

Mike Manos Announces Chiller-Side Chats, Raises Good Questions – Answers?

Mike Manos kicked off his “chiller-side chats” concept on his blog.  And, this is good to see someone bringing up the conflicts in data center design and operations.

With this post, I am kicking off a series of posts in which my sincerest wish is to help all three groups during these stressful times.   Having spent significant time in all three camps I will offer up my own personal take on the issues at hand.  I am calling them Chiller-Side Chats.   From time to time I will post my thoughts on various issues aimed at bridging the communication between these organizations.  I strongly encourage anyone reading these posts to drop comments or offer up suggestions so we can have a lively discussion on these topics.

The three groups Mike refers to is real estate, business users, and data center eng/ops. Mike goes on highlights an issue.

Three worlds have collided and its never pretty.   In my experience and in conversations with many customers in all three categories its a time that fosters frustration, mistrust, and stress.  Its also a wonderful time for less than scrupulous vendors, contractors, and consultants to take advantage of the situation and cause poor decisions to be made.   I am not saying that all consultants are bad or ill intentioned, in fact, there are some phenomenal organizations and products out there.   Its just that you need to be aware of the biases and “religious” debates in this space. 

Different firms have different biases and religious affiliations. 

Sometimes the firm that wins the deal is the one who has the best sales team.

Mike is helping to create awareness for a problem I’ve seen for many years in the data center industry. 

And, the good thing I’ve already thought of an answer/method to address this issue.

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.

The trick is to get the right modeling tools, and this has been a difficult search.  The good thing is I’ve found a partner on this topic, and we’re working on data center modeling solutions.

Regulation Compliance is Next Step in Green Data Centers

DataCenterKnowledge has a post on Digital Realty Trust’s survey on concerns about regulation coming.

The changes in Washington are being felt in the data center. The changed political and regulatory climate is clearly seen in survey data released today by Digital Realty Trust, the largest wholesale data center developer. The company’s annual study of green data center trends in the U.S. found that 69 percent of data center executives said they were “extremely or very concerned” about government regulation, and a huge surge in interest in using carbon credits to offset greenhouse gas emissions.

“What dominated last year’s study was the need for clearer standards and best practices for green data centers,” said Jim Smith, CTO of Digital Realty Trust. “By contrast, what dominates this year’s study is companies’ concerns about potential government regulation and how that would impact data center operations.”

“Concerns about potential regulations are driving companies to look closely at their data centers and accelerate the process of implementing green initiatives to increase energy efficiency,” said Smith, who said concerns about government regulation are somewhat offset by good faith efforts by the Department of Energy and  Environmental Protection Agency to work with the industry and groups like The Green Grid. “We believe that collaboration between the government and data center professionals is the most effective approach to addressing data center energy efficiency.”

What most people don’t understand what comes with being green claims is an opportunity for gov’t officials to measure your compliance.  Regulations and compliance are ways opportunities to tax.

Should you be concerned?

What are the carbon impact of your data centers?  All the top data center operators know theirs.

Do you know yours?

Why are data centers vulnerable?  They are owned by rich companies which can afford to pay carbon impact taxes.

PUE applied to PCs,

Ade Miller has a post on the idea of applying PUE to PCs.  What is the total power used by a PC divided by power used by the PC motherboard and peripherals?

How Green is Your PC? Estimating Power Usage Effectiveness

Tuesday, May 12, 2009 – 3:00 am

Evaluating data center efficiency.How efficient is your PC? Here’s a thought… How about taking some ideas from the people who run data centers? Turns out data centers use a measure called Power Usage Effectiveness (PUE) to assess how energy efficient they are:

Power usage effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. PUE is therefore expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1.
- SearchDataCenter.com

Err… So what does that mean for your PC? What if you think about the PC on your desk as a mini data center. How would you work out it’s PUE?

This brings up an interesting concept of publishing a PUE for IT equipment.  Where is the power overhead going?

Unfortunately not all of the power drawn by your PC makes it to the parts that matter. Power supplies aren’t perfectly efficient. So the next thing to do is factor in the computer’s power supply (PSU) efficiency. You can probably get this from the manufacturers web site. If you’re lucky they’ll give you a graph showing the efficiency under different loads like the one on the right for my Corsair TX650W. If not pretty much all manufacturers will give you an average number, especially if its 80 Plus rated. If not you can take the average number quoted.

What’s interesting about the graph is it shows how it’s possible to use an efficient PSU inefficiently by mismatching it to the rest of the PC. The efficiency peaks and drops off for very low and very high power consumptions.

For example for my my developer/gaming machine the power reading under load is 240W, this is 240/650 = 37% of the PSUs maximum load. From the graph above this gives an efficiency of 83% for a 110V circuit so 240W * 83% = 199W is actually delivered by the PSU to the rest of the computer. Now you know the amount of power actually being delivered by the PSU.

Typical layout of a development or gaming PC. Unfortunately some of the components inside your computer aren’t actually contributing to the bottom line, they’re just there to cool the bits that are. Namely… the fans.

 

 

 

 

 

Here are PUE numbers for Ade’s equipment.

I found this article on eweek on server fan efficiency.

Server fans: How to optimize the power used

Second only to the power supply, server fans have become a large user of power (other than the actual computing-related components themselves). As servers have become smaller and smaller—and now commonly pack several multi-core CPUs in a 1U-high server—the challenge of moving a sufficient amount of air through the server requires multiple small, high-velocity fans. They need to push air through very small restrictive airflow areas within the server and the very small intake and exhaust areas at the front and rear of the server chassis. 

These fans can consume 10 to 15 percent or more of the total power drawn by the server. And since the fans are DC, they draw power from the power supply, thus increasing the input power to the server, again multiplied by the inefficiency of the power supply. In addition, in 1U servers, most or all of the airflow is routed through the power supply fans since there is virtually little or no free area on the rear panel to exhaust the hot air.

To improve efficiency, many new servers have thermostatically-controlled fans which raise the fan speed as more airflow is needed to cool the server. This is an improvement over the old method of fixed-speed server fans that run maximum speed all the time. However, these variable speed fans still require a lot of energy as internal heat loads rise and/or input air temperature rises.

For example, if the server's internal CPUs and other computing-related components draw 250 to 350 watts from the power supply, the fans may require 30 to 75 watts to keep enough air moving through the server. This results in the overall increase in server power draw as heat density and air temperature rises in the data center. In fact, studies that have measured and plotted fan energy usage versus server power and inlet air temperatures show some very steep, fan-related power curves in temperature-controlled fans of small servers.

Stop the Uptime Spam Machine!

For those of you who attend Uptime Events, you’ve been a victim of Uptime’s Spam Machine.  I am sitting with 4 other data center professionals who all have been victims of the Uptime Spam.  Before the conference I was receiving 3 – 6 pieces of e-mail a day.

Unfortunately, all this spam is leaving a bad taste regarding Uptime.  Uptime is my leading spam sender.

Here is the latest spam email from Bruce Taylor advertising Tile Flow.

Making Green Data Centers

Dear Data Center Professional:
The energy consumed by the cooling infrastructure in a data center can be significantly reduced by optimizing the cooling performance, which involves achieving an airflow pattern that minimizes the mixing of hot and cold air. This optimization also reduces the operating cost and the emission of greenhouse gases.
The optimization of cooling performance requires a good understanding of airflow and temperature distribution in the data center. This understanding is best achieved via computational modeling based on the Computational Fluid Dynamics (CFD) technique.
