Chinese electronic government (E-Government) has achieved great success in several years, to quicken the pace of building E-Government, the central government of China has programmed to establish four governance information resource databases in next five years, data center construction in the developed cities is becoming an important project for present China¿s E-Government. Through investigation and analysis requirements of Nanhai city for data and business, this paper presents the architecture of data center, which is composed of six main components: data share and exchange platform, kernel database, support application platform, application database, data center management platform, and data center security platform. Extensible markup language (XML) and data warehouse technology are adopted for data center. Proposed method has already been successfully used in data center of Nanhai city, which is listed as the pilot cities for Model Project of China's E-government application.
Data center design of optimal reliability is adversely concerned not only investment, recovery times and lost opportunity costs, but also effected company's reputation and customers' confidence. Reliability of the power distribution system (PDS) for a data center depends upon numerous electronic parts, system of systems: component's inherent characteristic (CIC); system connectivity topology (SCT); system integration, and operating conditions. Different business activities are required the different level of fault tolerance of power outages in varying degrees of risks. A research question arises upon “what is the best appropriated level of data center reliability/availability at the optimal acceptable costs?” Research findings propose an optimal balance between data center system reliability and investment costs for each business case requirement.
An efficient cost effective novel modular scalable Data Center topology using Direct Current Uninterruptible Power Supply (DC UPS), server power supply with DC input and Cooling Distribution Unit (CDU) for IT load incorporating hybrid (both AC and DC voltage) distribution has been proposed in this paper. There is mismatch of infrastructure (both mechanical and electrical) capability and IT load in the existing Data Center. It takes years to reach equilibrium when IT load is balanced with infrastructure load capabilities. Major energy efficiency improvements and technological innovation of the Data Center industry had not been achieved for both electrical and mechanical infrastructure in the past, even as computing hardware and software follow Moore's law and has become efficient. A detailed analysis of the topology is presented to validate effectiveness of the proposed topology. Efficiency improvement and cost reduction of the proposed Data Center topology is found to be quite significant.
Global climate change is one of the challenges of our time. Due to ever increasing demand, data center providers have to consider the ecological effects of their business. Greenhouse gas (GHG) emissions are very likely to contribute significantly to climate change and, therefore, should be reduced. In data centers, GHG emissions are not only caused by the consumed energy for data center operation, but also originate from other life cycle phases of IT components, such as manufacturing. However, when minimizing GHG emissions of data centers, the effects on cost and quality of offered IT services should also be considered. Therefore, an optimization problem is introduced in this paper on the basis of redundancy allocation problems which minimizes IT service costs and GHG emissions subject to an availability service level objective. Conducted experiments using data from a real-world use case demonstrate that emissions can be reduced significantly with only slightly increased cost if these are considered in an optimization approach.
There is a large disconnect between the design of electronic equipment and the design of the data centers that house them, and yet as the industry is well aware, they are intricately related. A novel simulation method to join these two systems is presented here. A conceptual design data center is created in a simulation tool, then comparisons are made between designs that use generic server information and a simplified server model (SSM). SSMs are created using an innovative black box approach for determining inlet and exit heat and flow parameters, which are obtained from a detailed server model. It can be seen that using server details rather than the traditional generic models commonly used today generate different results.
In this paper, we present EETCO: an estimation and exploration tool that provides qualitative assessment of data center design decisions on Total-Cost- of-Ownership (TCO) and environmental impact. It can capture the implications of many parameters including server performance, power, cost, and Mean-Time- To-Failure (MTTF). The tool includes a model for spare estimation needed to account for server failures and performance variability. The paper describes the tool model and its implementation, and presents experiments that explore tradeoffs offered by different server configurations, performance variability, MTTF, 2D vs 3D-stacked processors, and ambient temperature. These experiments reveal, for the data center configurations used in this study, several opportunities for profit and optimization in the datacenter ecosystem: (i) servers with different computing performance and power consumption merit exploration to minimize TCO and the environmental impact, (ii) performance variability is desirable if it comes with a drastic cost reduction, (iii) shorter processor MTTF is beneficial if it comes with a moderate processor cost reduction, (iv) increasing by few degrees the ambient datacenter temperature reduces the environmental impact with a minor increase in the TCO and (v) a higher cost for a 3D-stacked processor with shorter MTTF and higher power consumption can be preferred, over a conventional 2D processor, if it offers a moderate performance increase.
The data center industry is focused on improving the energy efficiency of modern data centers due to their increasing energy costs and consumption, and the consequent carbon emissions. However, there is a lack of adopted process or metrics for data center cooling performance; this potentially puts facilities at risk from the unseen consequences of focusing on energy efficiency alone. The challenge for a data center operator is how to assess cooling performance. The facility's design likely makes assumptions about what IT equipment will be installed and how it will be configured that are not reflected in the operational configuration. This paper uses engineering simulation based on computational fluid dynamics (CFD) to show the relationship between the quantity of IT equipment that may be safely installed and the efficiency of the cooling system. Both are affected by changes to the cooling system settings and any IT equipment/applications deployed. The IT heat load and airflow requirement varies in legacy/enterprise style data centers and virtualized/cloud data centers alike, and this affects the cooling requirement. Using engineering simulation to predict the consequences of change provides a valuable complementary tool to the operator: it gives insight on how to avoid lost capacity, and helps them to better configure their facility when making decisions on infrastructure, IT deployment, or - in a virtualized environment - application deployment.
Energy consumption in data centers can be reduced by efficient design of the data centers and efficient management of computing resources and cooling units. A major obstacle in the analysis of data centers is the lack of a holistic simulator, where the impact of new computing resource (or cooling) management techniques can be tested with different designs (i.e., layouts and configurations) of data centers. To fill this gap, this paper proposes Green Data Center Simulator (GDCSim) for studying the energy efficiency of data centers under various data center geometries, workload characteristics, platform power management schemes, and scheduling algorithms. GDCSim is used to iteratively design green data centers. Further, it is validated against established CFD simulators. GDCSim is developed as a part of the BlueTool infrastructure project at Impact Lab.
In this paper we measured and analyzed the workload on Yahoo! Video, the 2nd largest U.S. video sharing site, to understand its nature and the impact on online video data center design. We discovered interesting statistical properties on both static and temporal dimensions of the workload; they include file duration and popularity distributions, arrival rate dynamics and predictability, and workload stationarity and burstiness. Complemented with queueing-theoretic techniques, we extended our understanding on the measurement data with a virtual data center design assuming the same workload as measured, which reveals results regarding the impact of workload arrival distribution, service level agreements (SLAs) and workload scheduling schemes on the design and operations of such large-scale video distribution systems.
This paper will describe two recent advances in Computational Fluid Dynamics (CFD) modeling as it pertains to data center design. In particular, the paper will define the use of the Capture Index (CI) in data center analysis, and will discuss the importance of accurately modeling coolers. Secondly, the article will describe Mentor Graphics' own $30M data center project currently in development. Two new centralized data centers will consolidate the resources of more than 20 local data centers in Europe and North America. One will be built in Shannon, Ireland, and another in Wilsonville, Oregon. By consolidating data centers, Mentor will see gains in capacity, efficiency, and redundancy while reducing operational costs.
