I can only repeat my initial statement: > Multi-dimensional RS codes are an easy way to get to an absurdly huge size for real. "Multi-dimensional" may mean 3,4,..,10 dimensions. "Absurdly huge" means a petabyte and beyond. "For real" means practical recovery of swaths of lost or damaged data.
"Fountain LDPC codes" are essentially one-dimensional. Extending them to the ability of recovering an annihilated data center would make them impractical. Making them multi-dimensional would make them inferior to RS (which is still MDS in every single dimension). |
