Distributed Repair Schemes for Reed-Solomon Codes With Multiple Erasures
Xing Lin · 2023
The use of Reed-Solomon (RS) codes in distributed storage systems is ubiquitous. In recent years, the repair schemes for RS codes with one or multiple failed symbols that can lessen communication cost in the repair (i.e., repair bandwidth) have been presented in literatures. However, the existing distributed repair schemes of RS codes can only repair $e=2,3$ erasures. In this paper, two distributed repair schemes for RS codes with $e\geq 4$ erasures are proposed for the first time.
