RAFI: Risk-Aware Failure Identification to Improve the RAS in Erasure-coded Data Centers

Fang, J ; Wan, S ; He, X ( July 2018 , The USENIX Annual Technical Conference (ATC))

Data reliability and availability, and serviceability (RAS) of erasure-coded data centers are highly affected by data repair induced by node failures. Compared to the recovery phase of the data repair, which is widely studied and well optimized, the failure identification phase of the data repair is less investigated. Moreover, in a traditional failure identification scheme, all chunks share the same identification time threshold, thus losing opportunities to further improve the RAS. To solve this problem, we propose RAFI, a novel risk-aware failure identification scheme. In RAFI, chunk failures in stripes experiencing different numbers of failed chunks are identified using differentmore »« less
