“…Traditional cooling manages the temperature of the room as a whole, however, this is not as efficient as more targeted cooling. Moving from cooling the entire room to focused cooling of a row of servers, or even a specific rack, can achieve energy savings of up to 29% 60 , and is the subject of a Google patent granted in 2012 61 . This is becoming necessary because of the increase in rack density.…”

The information communication technology sector will experience huge growth over the coming years, with 29.3 billion devices expected online by 2030, up from 18.4 billion in 2018. To reliably support the online services used by these billions of users, data centres have been built around the world to provide the millions of servers they contain with access to power, cooling and internet connectivity. Whilst the energy consumption of these facilities regularly receives mainstream and academic coverage, analysis of their water consumption is scarce. Data centres consume water directly for cooling, in some cases 57% sourced from potable water, and indirectly through the water requirements of non-renewable electricity generation. Although in the USA, data centre water consumption (1.7 billion litres/day) is small compared to total water consumption (1218 billion litres/day), there are issues of transparency with less than a third of data centre operators measuring water consumption. This paper examines the water consumption of data centres, the measurement of that consumption, highlights the lack of data available to assess water efficiency, and discusses and where the industry is going in attempts to reduce future consumption.

“…A lot of researchers reported the drawbacks of traditional raised floor cooling architectures including (a) high pressure and temperature drops of cooling air in the raised floor plenum 3 and low supply air flow rate at racks intake, 4 (b) hot air recirculation and cold air bypass, 5 (c) hot spots for the servers placed at low levels of the racks, 6 and (d) un-efficient cooling system due to high losses. 7 Accordingly, a new data center cooling architecture named as in-row cooling architecture has been developed and rapidly sprit.…”

“…Jin et al 3 conducted a comparison study between the different architectures of data centers cooling systems. Moazamigoodarzi et al 4 compared between the airflow rates needed by the different cooling architectures to maintain the servers at safe operating temperatures. Chu et al 7 reviewed air flow management in data centers and showed that the main controlling factor is the length of air flow paths.…”

“…A technique, proposed by Hosein Moazamigoodarzi et.al [33] in their paper can be a solution for improving the energy savings of the Data Centres with the implementation of computational fluid dynamics that can determine the temperature distributions and characteristic airflow for several cooling architectures like row-based, room-based and rack-based. The outcome of this proposed method may be treated as important methods to cool these architectures by inform the thermodynamics models of power consumptions.…”

In this era of modern technology, the cloud computing is considered as the most vibrant and indispensable part of the world of Information & Communication Technologies which is shaping the modern networking technology by introducing a new door with technical experiments for conserving the environment. It is empowered to rise the energy efficiency by reducing the carbon emissions that leads the transformation of cloud computing into green cloud computing. The buzzword term "Green cloud" is the combination of two terms "green" and "cloud" to symbolized the concept of ecofriendly environment with the Internet that is basically known as cloud computing. Even though the immense power of modern technology already gripped the environment and destroying the nature and environment that is not a renewable resource and it obvious has a great impact on life. Therefore it rises the awareness regarding environmental impact of the computing and so that green technology is gaining the importance accordingly. In this survey paper, we define a systematic approach to analyse different data centres' energy efficiency along with the concepts of diminishing the cost of the data centres by utilizing the cooling systems efficiently.
