This paper is built on the hypothesis that a national repository will bring Ethiopian researchers, lecturers and students closer to trends in academia worldwide, we took the model of The Fundamentals of High Performance Computing (HPC) Architectures and employing many Processing Elements (Repository) once. Repositories are generally considered to accommodate digital research center platforms, as a distributed digital library consists of material on separate machines connected via a network. The challenge of managing information will include the decision on how to store information, how to get connected, how to search and retrieve material. Methods such as the distributed library, which hides the actual server architecture by allowing the user to interact with whichever library node is nearest to them have been considered and discussed by experts. This paper highlights the need to enable people to access institutional repositories by exploring the architecture of the infrastructure. It also will explore how to enable authors to become active and independent users in all the processes that a repository offers for users and will also share lessons learnt in Ethiopia during the phase of setting up NADRE at university level and making NADRE available to researchers, lecturers, and students.
