The Design and Implementation of a High-Performance Log-Structured RAID System for ZNS SSDs
Jinhong Li, Yiyang Geng, Qiuping Wang +2
Zoned Namespace (ZNS) defines a new abstraction for host software to flexibly manage storage in flash-based SSDs as append-only zones. It also provides a Zone Append primitive to f…
An In-Depth Comparative Analysis of Cloud Block Storage Workloads: Findings and Implications
Jinhong Li, Qiuping Wang, Patrick P. C. Lee +1
Cloud block storage systems support diverse types of applications in modern cloud services. Characterizing their I/O activities is critical for guiding better system designs and op…
Separating Data via Block Invalidation Time Inference for Write Amplification Reduction in Log-Structured Storage
Qiuping Wang, Jinhong Li, Patrick P. C. Lee +3
Log-structured storage has been widely deployed in various domains of storage systems, yet its garbage collection incurs write amplification (WA) due to the rewrites of live data.…
Repair Pipelining for Erasure-Coded Storage: Algorithms and Evaluation
Xiaolu Li, Zuoru Yang, Jinhong Li +4
We propose repair pipelining, a technique that speeds up the repair performance in general erasure-coded storage. By carefully scheduling the repair of failed data in small-size un…
