Since energy-related costs make up an increasingly significant component of overall costs for data centers run by cloud providers, it is important that these costs be propagated to the tenants in ways that are fair and promote workload modulation that is aligned with overall cost-efficacy. We argue that there exists a big gap in how electric utilities charge data centers for their energy consum...

Modern datacenters assemble a very large number of disk drives under a single roof. Even if economic and technical factors where to make individual drives more reliable (which is not at all clear, given the commoditization of the technology), their sheer numbers combined with their ever increasing utilization in a well-balanced design makes achieving storage reliability a major challenge. In th...

In recent years, the scale of datacenters has become larger due to the explosive increase in the amount of digital data. As a result, the growth of energy consumption is an important factor in the management cost of datacenters. Storing and processing such large volumes of data by database applications are the core technologies in this Big Data era. However, storage accounts for a significant p...

The Environmental Data Abstraction Library provides a modular data management library for bringing new and diverse data-types together for visualisation within numerous software packages, including the ncWMS viewing service, which already has very wide international uptake. The structure of EDAL is presented along with examples of its use to compare satellite, model and in situ data types withi...

Data centers form a key part of the infrastructure upon which a variety of information technology services are built. As data centers continue to grow in size and complexity, it is desirable to understand aspects of their design that are worthy of carrying forward, as well as existing or upcoming shortcomings and challenges that would have to be addressed. We envision the data center evolving f...

All the internet services available these days are dependant and running in data centers. Companies like Google, Facebook, and Microsoft hosts millions of servers in their data centers to provide services to their users [19]. The enormous size of data centers leads to huge energy consumption. According to a news article, Google drew 260 MW of power in 2011 [6] that cost millions of dollars. Rec...

Data centers form the underpinnings of the global technology revolution that is cloud computing. There is enormous pressure for data center growth and expansion, to meet the computational demands of an increasingly digital world. With energy costs overtaking server costs in data centers, energy is fast becoming a significant bottleneck to data center scale-out. Further, the global data center e...
