Rack-Aware Minimum-Storage Regenerating Codes with Optimal Access for Consecutive Node Failures
Jiaojiao Wang, Xun Guan · 2024
We study the access complexity of repairing MDS array codes in a rack-aware storage model, that allows collective information processing among nodes within the same rack. We construct a family of MDS array codes that only requires accessing the minimum number of symbols to repair consecutive failed nodes in a single rack.
