Author Proposes O-RAID To Preserve Orbital Data
Ravinda Meegama, a senior computer science professor, proposes a constellation-level RAID architecture called Orbital Redundant Array of Independent Devices (O-RAID) that stripes data and parity across neighboring satellites via inter-satellite links to preserve on-orbit data. He argues this patent-pending approach (US Provisional No. 63/934,397) and use of geostationary moon orbit nodes can enable self-healing, ground-independent storage for LEO and lunar missions.
Key Points
- 1Proposes O-RAID: stripe data and parity across satellites using inter-satellite links for resilience.
- 2Provides mathematical reconstruction enabling self-healing clusters without relying on ground replication or spares.
- 3Signals operators to treat constellations as distributed storage, informing GMO lunar data-center designs.
Scoring Rationale
Novel, industry-scale redundancy architecture merits high impact; limited by single-author proposal and absence of experimental or operational validation.
