Information audit in electricity utilities: Roles, methodologies, issues and challenges

Information audit is crucial in understanding the current state of an organisation. By implementing information audit, the needs, the available resources and the gaps are made known to the top management of an organisation, thus helping them to identify steps to be taken to improve the way they manage information in order to stay competitive in their business. Several framework and methodologies were introduced, aimed at providing step by step guidelines to organisations in executing information audit while maximizing the benefits of information audit itself. However, despite the benefits information audit carries, only a minimum number of organisations put information audit into practice and this indicates that current developed framework and methodologies fail to convince organisations to implement information audit. This includes organisations in Electricity Supply Industry (ESI). This paper reviews existing information audit framework and methodologies applicable to ESI and discuses some issues and challenges in implementing information audit based on previous literatures. This review is a preliminary study of a research aims at proposing a new improved information audit framework for ESI.

Review on data center issues and challenges: Towards the Green Data Center

Data centers are the backbone of the variety internet services such as web-hosting, e-commerce, and social networking. Business relying on the DC services is showing an increasing and DC operators facing challenges to manage the DC resources. In order to cater the increase demand, DC operators are installing additional equipment in the DC. Thus, many research have highlighted the increasing trend of energy consumption in DC originates from the IT systems such as server, storage, network and from the non-IT system such as cooling system and power system. Looking into IT system, one of the solutions that may reduce the energy consumption in the DC is to adopt the Green Data Center using the green computing. However, DC operators are facing many issues and challenges and the most discussed in the literature are reliability and performance, resource management and energy management. This paper reviews the issues and challenges on the IT systems and to adopt the Green Data Center to assist DC operators moving towards the Green Data Center.
