From Linear Exact Repair to Mixed-Alphabet Codes: The Bandwidth-Subpacketization Tradeoff of MDS Array Codes
Zihao Zhang, Guodong Li, Sihuang Hu
MDS array codes achieve optimal storage efficiency in distributed storage systems, but their repair bandwidth depends critically on the sub-packetization level. While the theoretic…
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…
Lower Bounds on the Sub-Packetization of Optimal-Access MSR Codes for Multiple-Node Repair
Lewen Wang, Zihao Zhang, Sihuang Hu
We establish lower bounds on the sub-packetization of optimal-access MSR codes in the context of multiple-node failures. These bounds generalize the tight bounds for single-node fa…
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…
