This document discusses how the IBM XIV Storage System is designed to significantly reduce power consumption compared to other storage systems. It achieves over 65% lower power usage through an architecture that optimizes capacity utilization, eliminating unused "orphaned" storage space and using thin provisioning to allocate more virtual storage capacity than actual physical capacity installed. This allows customers to purchase only the storage needed currently while still having room for future growth. The efficient architecture also reduces the amount of hardware required, further cutting power and cooling costs while still providing high-performance storage.

Green IT in the Boardroom
Spreker: Jose Iglesias (VP of Global Solutions, Symantec)
At the same time that data centers are running short on space and power, IT organizations are also finding themselves dealing with skyrocketing amounts of information. But such challenges often have a way of presenting new opportunities. Today, Green IT is re-shaping the data center and bringing IT to the forefront in the boardroom. Energy efficiency is not just a set of quick fixes like virtualizing everything or focusing on new hardware – but rather a fundamental shift in how to approach the problem from the start by leveraging an existing investment in software and planning for how to save “green” while “going green” year over year. It covers the entire IT organization including the endpoints, servers, storage and communications. Jose will cover the practical issues of implementing green IT technologies into businesses and what the consequences are locally and across the globe.

Why are you paying for wasted energy in IT ?
Energy costs continue to climb and yet up to a third of the money companies spend on power could be wasted due to inneficient IT infrastructure. Take a serious look at your IT energy use.
The document discusses the next wave of green IT and making data centers more energy efficient. It notes that data center energy costs are significant and that McKinsey predicts data centers will produce more greenhouse gases than airlines by 2020. It provides best practices for building sustainable green data centers, including exploiting virtualization, improving server utilization rates, and designing efficient cooling systems.
Organizations are increasingly concerned about the energy consumption of their data centers, which account for a large portion of business energy usage. The document outlines several approaches for making data centers more energy efficient, including retiring legacy systems, enhancing power management on existing systems, migrating to more efficient platforms like blade servers, implementing virtualization to consolidate servers, standardizing on server performance matching application needs, and right-sizing power and cooling infrastructure to avoid overprovisioning. Taken together, these strategies can significantly reduce a data center's energy consumption and associated costs.
Cloud computing can stay green through efficiency gains and virtualization, but it also uses significant energy. While cloud operations consume more absolute energy, the energy is used more efficiently due to technologies like virtualization and server consolidation in large data centers. Cloud vendors have economic incentives to increase efficiency and reduce environmental impact through scaling, automation, minimizing resource use, and building sustainable data centers. The transition to cloud computing can have environmental benefits in addition to economic benefits for organizations.
This document discusses approaches to green IT, including virtualization, power management, efficient storage, video cards, displays, remote conferencing, product longevity, algorithmic efficiency, resource allocation, terminal servers, and operating system support. It notes that data centers consume a huge amount of power for servers and cooling, costing $4.5 billion annually. Organizations can reduce their "data footprint" and deployment/management resources through technologies like database solutions for massive data analysis and open-source software. This helps save money and resources while making operations more environmentally friendly.
Why are you paying for wasted energy in IT?
Energy costs continue to climb and yet up to a third of the money that companies spend on power could be wasted(1) owing to inefficient IT infrastructure. Power demands are predicted to outstrip supply in the next few years, so those costs won’t comedown. Energy regulations and carbon reduction targets are adding to the pressure. So why aren’t you taking a serious look at your IT energy use?
Green IT refers to the efficient use of computing resources to reduce environmental impact. It has become increasingly important due to rising energy consumption from data centers and electronic devices. While adoption of green IT practices does not have to be costly, barriers include lack of management support, expertise, and clear implementation guidelines. CIOs play a key role in educating stakeholders and creating green IT plans that quantify potential cost savings. Simple practices like powering down devices after hours can reduce energy usage by 40%. Investing in more efficient equipment and data center design also helps organizations lower costs and emissions. Green IT is not a passing fad due to growing political and social pressures to address climate change.
ScottMadden has developed an approach for analyzing data center requirements and driving improvements in existing data center retrofits. Our approach takes into account the technological requirements, the physical attributes of a data center, and the requirements for a rigorous measurement and verification program needed to ensure improvements actually capture the energy efficiently gains and the resultant greenhouse gas reductions.

The 2025 Huawei trend forecast gives you the lowdown on data centre facilitie...Heiko Joerg Schick
The document summarizes 10 trends predicted to shape data center facilities by 2025:
1. Power density of 15 to 20 kW/rack will be predominant as CPU and server capacity increases.
2. Data centers will require scalable architectures to support evolving IT over 10-15 year lifecycles.
3. The average PUE of new Chinese data centers will drop to 1.1 as energy efficiency, reduction, and sustainability become greater challenges.
The document discusses data center efficiency and focuses on Google's approach. It covers how Google builds its own custom data centers rather than relying on standard industry equipment and practices. It also describes how Google recommends five methods for reducing power consumption, which include measuring PUE, managing airflow, adjusting thermostats, using free cooling, and optimizing power distribution. The document notes that around 2% of global greenhouse gas emissions result from computing activities, with data centers accounting for 15% of that and large internet data centers making up 5%.

Reclaimed orphaned capacity
One of the drawbacks of most enterprise storage systems is that,
over time, an average of 9 to 15 percent of capacity becomes lost
and unusable. The complexity of volume management, volume
striping for performance and the ever-changing nature of

expensive than buying additional storage.
