Harmonizing the PUE Metric

While singing in the green choir, apparently not everyone has been singing from the same page of the power usage efficiency (PUE) hymnal. A global task force was formed two years ago to deal with the apparent lack of harmony. The result, "Harmonizing Global Metrics for Data Center Energy Efficiency," is a 12-page document from The Green Grid that should have the U.S., the European Union and Japan presumably all singing together on key. 

The key organizations involved in the task force are: the U.S. Department of Energy’s Save Energy Now and Federal Energy Management Programs; U.S. Environmental Protection Agency’s ENERGY STAR Program; European Commission Joint Research Center Data Centers Code of Conduct; Japan’s Ministry of Economy, Trade and Industry; Japan’s Green IT Promotion Council; and, of course, The Green Grid.

The ASHRAE Data Center Weather Report

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) announced that the climate in data centers is going to be warmer as it expands the recommended environmental envelope to improve energy efficiency. In fact, in what would have been considered heresy just a few years ago, it is envisioning and advocating the more common use of non-mechanical (compressor-less) cooling – so called “free cooling” – economizers using ambient air temperatures (within limits) to cool the data center.

The details of the expanded temperature and humidity ranges are going to be released in the soon-to-be-published third edition of the ASHRAE datacom book, “Thermal Guidelines for Data Processing Environments.”

Sell your surplus IT capacity

The hype-word of the last few years is cloud. If you are not in or around the cloud then you are out of business. Besides that cloud is a new money-maker and money-saver in IT, it is an opportunity for you in all cases. Maybe you have used cloud capacity from Amazon, Microsoft, Google or other well-known or lesser-known brands. But what do you do with the surplus IT capacity that you have today? You sell it on the new cloud marketplace, offered by “an independent aggregator of surplus cloud capacity” called Green Clouds.

Becoming a cloud provider the traditional way, requires you to adjust your current business, where you take large financial risks in a highly competitive market. Becoming a cloud consumer requires you to select a cloud provider and make you worry about price, performance, security and legal ownership of your data. Green Clouds makes everybody a cloud provider and offers you, the cloud consumer, an independent marketplace to get your ISO27001 and SAS type II certified capacity.

What is the impact of the Green Clouds marketplace to your OpenDCME score?

OpenDCME quadrant

Provider (sell capacity)

Consumer (buy capacity)

Facility

You can be successful in selling capacity from a medieval dungeon. You can be more successful when you lower your operational data center cost by becoming more energy efficient. This has not much to do with cloud, other than keeping the facility capacity and IT capacity aligned.

If you transfer current IT capacity to the cloud, your data center must scale down. Otherwise your scores will drop. But if you put new services into the cloud, there is no impact here.

IT Assets

The utilization rate of your hardware should improve. But in the end, if you have much more hardware capacity than is sold on the marketplace, you are still not scoring well.

If new services are created in the cloud, the scores will not change. If you move existing services to the cloud, the scores will drop and you should physically move hardware from your data center or switch it off waiting for better times. Or sell the capacity on the marketplace, which is your new alternative to surplus capacity.

Management

You have to be in control of the performance and capacity utilization of your sold capacity. As provider, you have to deliver the agreed performance and capacity. And in case your own business grows, you need to know what to do.

Is it cheaper to get capacity from the marketplace or use your own surplus capacity? First step: know your current and future capacity need by collecting trends.

Processes

As you have a new customer, that are anonymous users that use your sold capacity, you have to be more in control of what you have and what you do.

From a product lifecycle perspective it will become more easy; less iron to deal with. And in the end,  the marketplace gives you another option to easily grow or shrink your capacity. Managing capacity is still required otherwise there is no change in solving the surplus capacity challenge.

Inter-relationships between KPI's documented

Over the last days, each OpenDCME KPI got a detailed list of its relationship with other OpenDCME KPI’s. The KPI’s in the second quadrant (IT Assets) uses another approach than simply documenting the fact. Each relationship answers the question:

What is the impact of increasing the utilization by decreasing the installed capacity?

This particular approach is taken to show what happens when IT makes changes, primarily changes based on consolidation/virtualization projects. How does it impact the data center (quadrant 1 facility) and what is required on the processes (quadrant 4 processes) to be more successful? When turning one KPI to green (good), others can turn to red (bad). Be aware of the balance and do not try to optimize all at once; accept a (temporary) degradation as intermediate step.

The OpenDCME model will help you to take the next step to improve your competency. Set your first target to move from unconscious incompetence to conscious incompetence. In other words, accept that you can and have to improve. And where you are on the scale of the “four stages of competence” will vary per KPI.

Another often used management model to improve and control is the Deming Circle. But I would like to add a special entry-point to it. It is where you understand and accept the fact that you can and have to improve.
