Optimal Repair of MDS Array Codes
Zihao Zhang, Guodong Li, Sihuang Hu
Maximum distance separable (MDS) codes are widely used in distributed storage systems as they provide optimal fault tolerance for a given amount of storage overhead. The seminal wo…

Making Wide Stripes Practical: Cascaded Parity LRCs for Efficient Repair and High Reliability
Fan Yu, Guodong Li, Si Wu +2
Erasure coding with wide stripes is increasingly adopted to reduce storage overhead in large-scale storage systems. However, existing Locally Repairable Codes (LRCs) exhibit struct…

Constructing cooperative MSR codes with sub-packetization
Zihao Zhang, Guodong Li, Sihuang Hu
We address the multi-node failure repair challenges for MDS array codes. Presently, two primary models are employed for multi-node repairs: the centralized model where all failed n…
