Bounds and Optimal Constructions of Generalized Merge-Convertible Codes for Code Conversion into LRCs

Haoming Shi, Weijun Fang, Yuan Gao

Error-correcting codes are essential for ensuring fault tolerance in modern distributed data storage systems. However, in practice, factors such as the failure rates of storage dev…
