Distributed Data Storage on CubeSat Clusters
Obulapathi Nayudu Challa, Janise Y. McNair · Advances in Computing · 2013
The CubeSat Distributed File System (CDFS) is built for storing large files on small satellite clusters in a distributed fashion to support distributed processing and communication. While satisfying the goals of scalability, reliability and performance, CDFS is designed for CubeSat clusters which communicate using wireless mediu m and have severe power and bandwidth constraints. CDFS has successfully met the scalability, performance and reliability goals while adhering to the constraints posed by harsh environment and resource constrained nodes. It is being used as a storage layer for distributed processing and distributed communicat ion on CubeSat clusters. In this paper, we present the system architecture, file system design, several optimizat ions and report several performance measurements fro m our simu lations.
