Performance and stability of the chelonia storage system

Abstract

In this paper we present Chelonia, a storage system designed to fill the requirements gap between those of large, sophisticated scientific collaborations which have adopted the grid paradigm for their distributed storage needs, and of corporate business communities which are gravitating towards the cloud paradigm. The similarities to and differences between Chelonia and several wellknown grid- And cloud-based storage solutions are commented. The design of Chelonia has been chosen to optimize high reliability and scalability of an integrated system of heterogeneous, geographically dispersed storage sites and the ability to easily expand the system dynamically. The architecture and implementation in term of web-services running inside the Advanced Resource Connector Hosting Environment Dameon (ARC HED) have been described discussed earlier. In this paper we present results of tests in both local-area and wide-area networks that demonstrate the fault-tolerance, stability and scalability of Chelonia. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike License.
