Rack-Aware MSR Codes with Linear Field Size and Smaller Sub-Packetization for Tolerating Multiple Erasures

Hengming Zhao, Dianhua Wu, Minquan Cheng

In an $(n, k, d)$ rack-aware storage model, the system consists of $n$ nodes uniformly distributed across $n ˉ$ successive racks, such that each rack contains $u$ nodes of equal…

Explicit Constructions for Rack-Aware Minimum Storage Partially Cooperative Regenerating Codes

Hengming Zhao, Dianhua Wu, Minquan Cheng

The rack-aware storage model improves repair efficiency by exploiting locality within racks to minimize cross-rack traffic in a distributed storage system. While the partially coop…

On balanced $(Z_{4 u} \times Z_{8 v}, {4, 5}, 1)$ difference packings

Hengming Zhao, Rongcun Qin, Dianhua Wu

Let $K$ be a set of positive integers and let $G$ be an additive group. A $(G, K, 1)$ difference packing is a set of subsets of $G$ with sizes from $K$ whose list of differences co…
