Partial MDS Codes with Local Regeneration
Lukas Holzbaur, Sven Puchinger, Eitan Yaakobi, Antonia Wachter-Zeh · 2020
Partial MDS (PMDS) and sector-disk (SD) codes are classes of erasure codes that combine locality with strong erasure correction capabilities. We construct PMDS and SD codes where each local code is a bandwidth-optimal regenerating MDS code. The constructions require significantly smaller field size than the only other construction known in literature.
