As cloud applications proliferate and data-processing demands increase, server resources must grow to unleash the performance of emerging workloads that scale well with large number of compute nodes. Nevertheless, power has become a crucial bottleneck that restricts horizontal scaling (scale out) of server systems, especially in datacenters that employ power over-subscription. When a data-center hits...
Today, an increasing number of applications and services are being hosted by large-scale data centers. The massive and irregular load surges challenge data center power infrastructures. As a result, power mismatching between supply and demand has emerged as a crucial issue in modern data centers which are either under-provisioned or powered by intermittent power sources. Recent proposals have employed...
As the essential infrastructures for cloud computing, data centers are facing increasing pressure of capping tremendous power consumption and carbon emission. Currently, many proposals have leveraged energy storage devices (in the form of UPS batteries) to provide buffered energy during peak power demands for reducing data center power cost. In addition, energy storage devices are also used to smooth...
