Power Provisioning Scheme Enables Power and Carbon Constrained Data Center Servers to Scale Out More Efficiently

This data center power provisioning scheme, called Oasis, will enable power and carbon constrained centers to expand more economically and sustainably. The growing usage of online businesses, cloud-based computing, and data analytic workloads have forced data centers to continually expand their infrastructure. Higher server capacity has created power supply problems for large data centers that will soon exceed their power and carbon emission capacity in the near future. Conventional solutions for freeing up more power supply like consolidating servers, upgrading equipment, moving to cloud computing, or building new data centers are either highly expensive and time consuming or do not provide a long-term solution. Researchers at the University of Florida have developed Oasis, a power provisioning architecture that enables power-constrained data centers to scale out, facilitating power capacity planning and on-demand expansion. Oasis will work within the Optimized Oasis Operation (Ozone) system, a multisource driven power management scheme contributing to Oasis’ overall system efficiency and reliability.


Power provisioning scheme allowing data centers effectively expand scale out opportunities


  • Consolidates a variety of systems, maximizing system efficiency and ease of use
  • Utilizes renewable power supplies and emerging battery architecture, extending compatibility with even future power sources
  • Collects and filters crucial runtime statistics and data from multiple systems, automatically optimizing power usage of multiple sources
  • Allows data centers to increase their power capacity incrementally, creating a “pay-as-you-grow” model that can greatly minimize the capital and operating expenditures
  • Uses modular renewable power sources, lowering the carbon footprint and negative environmental impact of datacenters


Oasis is a power provisioning system that can aggregate multiple and different power sources, specifically from modular and renewable energies. Oasis has integrated power systems that can convert power from highly-dense lithium-ion batteries to solar panels or wind turbines and incrementally provide power capacity, improving reliability, especially in many power failure situations. Oasis’ automated systems link power supply management and server system control that can enable real-time power supply driven workload scheduling. With the actual Oasis node unit, the power control hub integrates many key hardware components that allow easy system diagnosis and maximum power supply compatibility. The Ozone system could jointly optimize battery life and workload performance, extending battery life by more than 50 percent and reducing performance degradation of Oasis to 1 percent. The Oasis and Ozone power provisioning systems could offer unprecedented reliability and flexibility for many different data center operators based on their specific needs and expectations.
