Cost Benefits of Documenting Infrastructure Connectivity

Every change in connectivity has a cost, but trying to put in better management controls often fails. This paper looks at how organisations can make major savings in change and documentation costs by managers addressing the connectivity challenge.

Cold Aisle Containment for Improved Data Center Cooling Efficiency

Increasing power requirements for new servers have created the need to support higher density computing platforms in existing data centers. With kW per rack averages increasing from 3kW/rack to, in some extreme cases, more than 30kW/rack, the need for providing more efficient ways of cooling IT equipment is imperative. A number of rack manufacturers, and data center operators alike, are now advocating the use of “air containment” systems for meeting this challenge. By preventing the mixing of hot and cold air streams, data center cooling can be made more efficient and Computer Room Air Conditioner (CRAC) performance can be significantly improved. When deployed in well-designed and operated facilities, these containment systems look promising. This report documents the testing of a cold aisle containment system in a “live” data center. The goal of the test program was to benchmark the performance of Rittal’s Cold Aisle Containment (CAC) system by comparing data collected in the same data center operating under identical conditions with and without containment.

Understanding Data Center Cooling Energy Usage & Reduction Methods

Data center energy usage has risen dramatically over the past decade and will continue to grow in-step with the processor-intensive applications that support business and day-to-day life in the modern world. The growth of technology has driven the data center into a new phase of expansion, and while data centers themselves may vary over different industry segments, there are common factors influencing all of them including a need to do more with the same resources, or in some cases, even less. To this end, much has been done to increase server efficiency and IT space utilization, but the actual space and cooling infrastructure supporting these intensified loads has often not been properly addressed to keep pace with these developments—an important oversight since cooling can represent up to 42% of a data center’s energy usage. This white paper provides a clear understanding of the cooling and heat removal infrastructure requirements for the modern high density data center and methods that can be employed to reduce energy consumption and costs while increasing performance and operational efficiency.

High Density Cooling

In previous publications, Rittal Corporation has discussed the design and implementation requirements associated with deploying a high density cooling solution. Today, it can be said with a very high degree of certainty that the IT community is well aware of the critical issues of meeting the power and cooling requirements of the data center, and, in some cases, not having enough of one or the other, or even both. The discussions continue—from equipment vendors, to design engineers and consultants, facility personnel, various industry groups and even the government. All interested parties have their unique ideas and solutions, roadmaps and planning tools, and new products that will address these needs. In the middle are the end users, trying to make sense of it all, keeping up with the latest advances and information—making sure to get the most cost effective solution without penalizing performance. As a global provider of modular enclosure and high density cooling solutions, Rittal Corporation chartered an international engineering firm to review and analyze performance of the Liquid Cooled Package (LCP) system versus traditional air cooled systems. For the comparison and analysis, a “typical” data center with a pressurized raised floor and hot aisle/cold aisle row orientation using CRAC units was considered. The same heat load was then “installed” in a data center using only LCP units. The resulting report, summarized in this paper, addressed the various cost an

The Case for Liquid Cooling

This paper will explore opportunities to realize energy savings in data center chilled water systems through the use of close-coupled, closed-loop, water-cooled IT equipment cabinets. Energy usage of the chiller plant will be examined, identifying potential energy savings afforded by varying chilled water supply temperatures. Further, the paper will look at “free cooling” opportunities, using water-side economizers in conjunction with water-cooled cabinets to further expand energy savings potential.

The Realities of Airflow through Perforated Doors

Much has been written recently concerning the rapid increase of energy consumed in data centers by computer, storage, and network hardware. As theorized by Gordon Moore of Intel Corporation in the 1960’s, computer chip set processing power has doubled on average every 18 months since. The realization of this theory over the past 40+ years has resulted in a steady increase in the energy consumed in data centers. According to data published by the EPA in its report to Congress, data center energy usage doubled between the years 2000 to 2006 and is expected to double again by the year 2011. (1) The impact this energy usage is having on the US power grid, let alone the potential environmental impact, has all the makings of a crisis of catastrophic proportions. A significant contributor to this increased energy usage has been the data center facility electrical and mechanical infrastructure required to support the IT hardware. The EPA estimates that mechanical and electrical infrastructure equipment accounts for 50% of all data center energy consumption, with the mechanical load representing approximately half again, or 25%, of the overall energy. (2) Chiller energy usage is estimated to be 50% of the mechanical electrical load representing approximately 12.5% of total data energy consumption and represents the single greatest potential area for energy savings. Just a few short years ago; the debate was not centered on the practical and potential environmental implications of th
