New Design and Analysis of Error-Resilient LRCs for DSSs With Silent Disk Errors
Chanki Kim, Jong‐Seon No · IEEE Access · 2021
In this paper, for the resilience of hierarchical distributed storage systems (DSSs) with silent disk errors, binary error-resilient locally repairable codes (ER-LRCs) with high error and erasure correction capabilities are proposed, which have larger values of minimum bit-wise Hamming distance than the existing LRCs. Also, the modified mean time to data loss (MTTDL) values for the proposed ER-LRCs with silent disk errors as well as node failures are proposed. From the numerical analysis, it is shown that the proposed ER-LRCs have better MTTDL values when compared to the existing LRCs.
