Are Disks the Dominant Contributor for Storage Failures? A Comprehensive Study of Storage Subsystem Failure Characteristics
Building reliable storage systems becomes increasingly challenging as the complexity of modern storage systems continues to grow. Understanding storage failure characteristics is crucially important for designing and building a reliable storage system. While several recent studies have been conducted on understanding storage failures, almost all of them focus on the failure characteristics of one component - disks - and do not study other storage component failures. This paper analyzes the failure characteristics of storage subsystems.
