Convertible Codes: MSR-to-MSR Conversion with Optimal Access and Bandwidth
Yumeng Yang, Han Cai, Xianfu Lei +1
In this paper, we study convertible codes in the merge regime and focus on the minimum storage regenerating (MSR) setting, where both the initial codes and the final code admit opt…

A Transformation of Repairing Reed-Solomon Codes from Rack-Aware Storage Model to Homogeneous Storage Model
Yumeng Yang, Han Cai, Xiaohu Tang
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 c…
