Optimal Repair of $(k + 2, k, 2)$ 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…
