| Abstract | Numerical modeling of data centers was introduced nearly 10 years ago and has become ubiquitous in the industry. Aside from computational fluid dynamics, a number of alternative approaches have been investigated to reduce model runtime while maintaining accuracy. Less attention, however, has been paid to utilizing the output of such tools to assess the availability and operational margin of IT equipment in a conditioned environment. This paper introduces a new technique called Data Center Damage Boundary that is derived from fragility analysis techniques used in military applications to further understand the limitations of a particular data center's environmental control infrastructure. Using the methodology described herein, Damage Boundaries are defined that establish safe operating regimes for IT equipment within a given data center thermal environment. From this information the thermal capacity of a given region of influence within a data center can be determined, regions of inefficient operation can be identified, and the proximity of equipment within a zone to its damage boundary can be evaluated. Furthermore, the information can help save energy by operating the data center at a higher server inlet temperature, improve utilization of capital-intensive air-conditioning resources, reduce excessive redundancy, and thus lead to a lower total cost of ownership. This paper will introduce the method and demonstrate its use by applying it to the results of a computational fluid dynamics model. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
