This paper describes the scalable e-archiving repository system developed in the context of the E-ARK project. The system is built using a stack of widely used technologies that are known from areas such as search engine development, information retrieval and data-intensive computing, enabling efficient storage and processing of large volumes of data. The E-ARK Integrated Platform Reference Implementation Prototype takes advantage of these technologies and implements an OAIS-oriented repository system for creating, archiving, and accessing data as information packages. The system consists of software components including an efficient file handling infrastructure, a configurable and scalable ingest system, a powerful full-text-based search server, and a distributed repository providing file-level random access. This paper gives an overview of the architecture and technical components that have been used to build the prototype. Furthermore, the paper provides experimental results and gives directions for future work.
