Dynamic Power Allocation in Data Centers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power distribution systems in data centers often leave unused power due to conservative ratings of electrical devices and infrequent maximum current draws, leading to inefficiencies as devices do not utilize their full capacity simultaneously.
Innovation Solution
A dynamic power allocation system where computing machines request and prioritize power needs, with a scoring function to allocate power based on priority and availability, allowing for intelligent negotiation and redistribution among machines to optimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power distribution systems are built conservatively to supply devices' rated currents, then reliability is improved, but power utilization deteriorates
Solution Approach 1:
The patent implements dynamic power allocation where the power distribution system transitions from static conservative ratings to dynamic adjustment based on real-time demand. The system continuously monitors actual power consumption and reallocates capacity accordingly, allowing the same infrastructure to reliably serve variable loads without over-provisioning for peak theoretical demands that rarely occur simultaneously.
Solution Approach 2:
The system changes the operational parameters of power distribution by moving from fixed rated current values to variable actual consumption values. By monitoring real-time power usage and adjusting allocations dynamically, the system adapts parameters to match actual device needs rather than relying on conservative static ratings, thereby reducing unused capacity while maintaining reliability.
2Adaptability or versatility
If the number of power branches increases to serve more devices, then adaptability is improved, but power utilization deteriorates
Solution Approach 1:
The patent applies local quality by allowing each power branch to have its own dynamic allocation based on local demand characteristics. Rather than uniform conservative allocation across all branches, the system monitors and adjusts each branch independently according to actual device consumption patterns, enabling high adaptability while minimizing unused capacity on individual branches.
Solution Approach 2:
The system implements feedback mechanisms where power consumption data from each branch is continuously monitored and fed back to the allocation system. This feedback loop enables real-time adjustment of power distribution across multiple branches, allowing the system to adapt to changing device needs while optimizing utilization by redirecting capacity from underutilized branches to those with higher demand.
3Reliability
If electrical devices are rated for maximum current draw, then reliability is improved, but productivity deteriorates
Solution Approach 1:
The patent applies partial action by allocating power based on actual consumption needs rather than full rated capacity. Devices receive exactly the power they need to perform their functions reliably, without the excessive conservative margins built into traditional rated allocations. This partial allocation approach maintains sufficient power for reliable operation while eliminating wasted capacity that reduces overall system productivity.

AI summary
In a computer-implemented method, an electronic communication from a first computing machine is received and includes a power value and one or more priority values. The power value represents a request for a power allotment expected to be used during a predetermined time and the priority values represent priorities of tasks expected to be executed during the predetermined time. A score for the request is calculated using a scoring function and the received priority values as inputs to the scoring function. The score is compared to one or more other scores respectively associated with requests for power allotments from other computing machines and previously calculated using the scoring function following receipt of one or more electronic communications each including a power value and one or more priority values. A top-ranked score is identified and an electronic communication is sent to the associated computing machine granting the requested power allotment.
