What is O-RAID and how does it work in space?

O-RAID is a constellation-level RAID architecture that stripes data across multiple satellites via inter-satellite links, allowing for data reconstruction even if individual satellites fail.

Why can't traditional RAID be used on a single satellite?

Single satellites are too limited by mass, power, and volume to house the physical redundancy required for internal RAID.

How can data centers be established on the Moon without landing?

Data centers can be placed in stable orbits around the Moon, creating a high-bandwidth 'orbital cloud' to service surface assets.

O-RAID architecture ensures data survival even if individual satellites fail.
Lunar data centers could orbit the Moon, avoiding risky surface landings.

Space Data Centers: O-RAID Secures Orbital Data

Low Earth orbit is rapidly expanding with a new focus on space data centers, moving beyond simple communication relays. Initiatives are now deploying significant processing power in orbit, leading to a critical need for robust data resilience. Traditional methods like RAID are impossible on single satellites due to physical limitations.

A new "Orbital Redundant Array of Independent Devices" (O-RAID) architecture proposes treating entire satellite constellations as storage mediums. By distributing data fragments and parity across neighboring satellites via inter-satellite links, O-RAID ensures data can be mathematically reconstructed on the fly, even if individual satellites fail.
