Abstract
Suboptimal storage design has significant cost and power impact in large-scale datacenters. This article presents a modeling and generation framework for storage applications that captures spatial and temporal locality and I/O intensity, recreates application I/O loads, and enables storage-system studies without access to application code or full deployments. The methodology is validated with production traces and applied to SSD caching and defragmentation.
