Hardware Analytics and Lifecycle Optimization (HALO) at Facebook

This post introduces the Hardware Analytics and Lifecycle Optimization (HALO) system, which enhances site reliability by providing a comprehensive approach to monitoring, processing, and visualizing hardware data at scale. HALO integrates data from Lumberjack, asset/ticketing systems, and ODS to track SMART attributes, component logs, and environmental sensors. It employs anomaly detection, the Attribot tool for known issue identification, and Systemic Issue Detection (SID) for identifying emerging hardware problems. The outcomes include improved global hardware health through vendor collaboration and supply chain refinement, and informed hardware redesigns based on field experience, such as improved toolless serviceability and airflow design.
