A Transformation of Repairing Reed-Solomon Codes from Rack-Aware Storage Model to Homogeneous Storage Model
CoRR(2024)
摘要
In this paper, we address the node repair problem of Reed-Solomon (RS) coded
distributed storage systems. Specifically, to overcome the challenges of
multiple-node failures of RS codes under the rack-aware storage model, we
employ good polynomials to guide the placement of the conventional RS codes
into racks and then propose a novel repair framework for the resultant
rack-aware RS codes, which can transform its repair to that under the
homogeneous storage model. As applications of our repair framework, firstly we
present the repair scheme of multiple-node failures for some existing
constructions, which can only repair a single-node failure before. Secondly, we
deduce several new constructions of rack-aware RS codes supporting the repair
of multiple-node failures.
