The Work Plan of All4Green is divided into 8 distinct work packages, altogether lasting 30 months. Two work packages – that will last for the entire project’s duration and will run in parallel – are Project Management (WP1) and Dissemination and Exploitation (WP8).
WP2 designs the scenarios that the requirements process for the plug-in will be built on. It will carry through the whole requirements process (scenarios, use cases, software requirements elicitation, monitoring and validation), from a user oriented perspective for the plug-in/interface as a whole, not from the technical perspective for the components that plug-in will be made of. As a part of the scenario design, focus will be laid on the analysis of current business models including SLAs as well as on the suggestion of new business models and Green-SLAs fostering the cooperation within the eco-system (from a high level, business oriented perspective). To round up the business perspective, a market analysis will be carried through. In parallel, WP6 initial task will specify high-level All4Green technical requirements and ecosystem architecture.
In WP3, WP4 and WP5 the basis for the new paradigm of energy-aware collaboration inside the data centre ecosystem is established.
WP3 tackles the relation between the ICT end user and the data centre from a more technical point of view. It especially focuses on the analysis of current SLAs, as well as the modelling of Green-SLAs that can be processed by the All4Green building blocks. We start from noting that Green-SLAs are basically static (frame) contracts containing dynamic elements in so far, as the All4Green plug-in should be enabled to choose from several optional rules within the Green-SLA in an optimization process without re-negotiating with the end-user at the time of the optimization.
WP4 deals with the relationship between the energy provider and the data centre. It starts with analyzing the current situation of energy provision, in order to identify when and how requests from the energy provider to the data centre to reduce its energy consumption for a limited time-span can be made and have the greatest impact on the consumption of energy sources, on electricity losses due to transportation and on CO2 emission due to the substitution of “dirty, inefficient” sources by “clean, efficient” energy sources. WP4 then models the mechanisms in the data centre to adapt to the needs of the energy provider, with the plug-in being located at the data centre. It also suggests Green-SLAs between energy providers and data centres that of course have to be viewed in connection with the Green-SLAs between data centres and their customers.
WP5 analyzes the options for a federation of data centres to further increase the benefit of the collaboration among the eco-system by enabling additional strategies like work load shifting. It will model the management of multi-tenant data centre federations with respect to communication, energy and quality of service aspects. It will also model a negotiation process among the federated data centres that will suddenly or due to a request as specified by WP4 redistribute the load over the federations’ networks.
They shall be adaptable to the situational context in which the federations of data centres live, and capable of coping with uncertainty in load distribution and dynamics throughout federations of data centres between the energy provider and the data centre.
Work in WP3-5 will be performed in parallel, and will be brought together in WP6. WP6 merges the findings of the preceding technical work packages by implementing the building blocks of All4Green. It will start with developing a framework for a multi-agent system that will be utilized throughout the implementation process. The implementation itself will be organized according to the spiral software engineering model in two phases for the different All4Green computing styles.
WP7 tests the plug-ins in two phases as they are developed. It will start with an assessment phase of the test sites. Before the beginning of the real test cycles there will be a task to definition of work load specifications based on the results of the WP 3-5.
In WP8, the research results of All4Green will be disseminated and exploited. WP8 objectives will be reached by devising strategies for exploitation and dissemination of project results amongst European stakeholders. This should increase the potential for exploitation of these results to the advantage of consumers, users and other technology producers.
