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…
Efficient LSM-Tree Key-Value Data Management on Hybrid SSD/HDD Zoned Storage
Jinhong Li, Qiuping Wang, Patrick P. C. Lee
Zoned storage devices, such as zoned namespace (ZNS) solid-state drives (SSDs) and host-managed shingled magnetic recording (HM-SMR) hard-disk drives (HDDs), expose interfaces for…
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.…
