Carbon Responder: Coordinating Demand Response for the Datacenter Fleet
The increasing integration of renewable energy sources results in
fluctuations in carbon intensity throughout the day. To mitigate their carbon
footprint, datacenters can implement demand response (DR) by adjusting their
load based on grid signals. However, this presents challenges for private
datacenters with diverse workloads and services. One of the key challenges is
efficiently and fairly allocating power curtailment across different workloads.
In response to these challenges, we propose the Carbon Responder framework.
The Carbon Responder framework aims to reduce the carbon footprint of
heterogeneous workloads in datacenters by modulating their power usage. Unlike
previous studies, Carbon Responder considers both online and batch workloads
with different service level objectives and develops accurate performance
models to achieve performance-aware power allocation. The framework supports
three alternative policies: Efficient DR, Fair and Centralized DR, and Fair and
Decentralized DR. We evaluate Carbon Responder polices using production
workload traces from a private hyperscale datacenter. Our experimental results
demonstrate that the efficient Carbon Responder policy reduces the carbon
footprint by around 2x as much compared to baseline approaches adapted from
existing methods. The fair Carbon Responder policies distribute the performance
penalties and carbon reduction responsibility fairly among workloads
