报告主题：Autonomous Monitoring of Data Centre Operations
报告摘要：Today’s data centers (DCs) consume up to 3% of the energy produced worldwide, much of which is wasted due to over-cooling and under utilization of IT equipment. This wastage in part stems from the lack of real-time visibility of fine-grained thermal distribution in DCs. Wireless sensing is an ideal candidate for DC monitoring as it is cost-effective, facility-friendly, and can be easily re-purposed. However, sensor measurements only characterize the current states of the system and operations, and are not suitable for predicting future conditions and answering what-if questions. In this talk, I discuss the needs and challenges of data centre infrastructure management (DCIM) systems. I present our recent work on autonomous monitoring of data centre operations: 1) LEMoNet, a novel two-tier ultra-low energy wireless sensor network protocol stack that have been demonstrated experimentally to achieve high data yield and a nodal life time up to 14.9 years on a single lithium battery; 2) Thermal-piloting for sensor localization in data centres and 3) surrogate thermal dynamics modelling for online predictions.
