Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current out-of-band management systems for data centers face challenges such as limited API capabilities, reliance on wired connections and baseboard management controllers, and inadequate data aggregation and analysis across various services, leading to inefficient management and monitoring of rack-mounted computing devices.
Innovation Solution
The implementation of a Data Center Sensorfication, Control, Analytics, and Management Platform, referred to as Vapor CORE, which provides southbound and northbound APIs, enabling integrated management and monitoring services through a set of microservices that utilize power line communications and a distributed architecture to aggregate and analyze data from sensors and devices within the data center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional out-of-band management systems are used with wired connections and baseboard management controllers, then device control capability is provided, but system complexity and integration difficulty increase
Solution Approach 1:
The patent applies universality by enabling the power distribution network to serve dual functions: delivering electrical power to rack-mounted devices and transmitting management data simultaneously. This eliminates the need for separate wired management connections, reducing system complexity while maintaining device control capability. The power lines act as a universal medium for both energy and information transmission.
Solution Approach 2:
The patent merges the power distribution function and data communication function into a single integrated system. By combining electrical power delivery and management data transmission over the same physical infrastructure (power lines), the system reduces the number of separate components and connections needed, thereby lowering overall system complexity.
2Reliability
If multiple separate networks are used for data conveyance and device management, then security risk is limited and attack surface is reduced, but network integration and data aggregation become inefficient
Solution Approach 1:
The patent introduces an intermediary approach by using the power distribution network as a mediator for management communication. The system maintains network segmentation for security (keeping management traffic separate from data traffic) while enabling efficient data aggregation through the power lines. The power network acts as an intermediate communication channel that connects to multiple devices without requiring direct wired management connections to each device.
Solution Approach 2:
The power distribution network serves multiple functions simultaneously: it delivers electrical power to devices and transmits management data for monitoring and control. This multi-functionality enables efficient data aggregation across multiple devices through a single infrastructure, improving productivity while maintaining the security benefits of separate management and data networks.
3Adaptability or versatility
If wired connections and baseboard management controllers are deployed for each device, then out-of-band management is achieved, but installation complexity and maintenance difficulty increase
Solution Approach 1:
The patent applies self-service by utilizing the existing power distribution infrastructure that is already present in data centers to provide management capabilities. Instead of requiring separate management wiring and controllers for each device, the system leverages the existing power lines as the communication medium. This eliminates the need for additional installation work and reduces maintenance complexity, as the power network is already deployed throughout the facility.
Solution Approach 2:
The patent combines the power distribution infrastructure with management communication functionality. By merging these two functions into a single system, the patent eliminates the need for separate management wiring and controllers, significantly reducing installation complexity and maintenance burden while preserving out-of-band management capability.
4Ease of operation
If rack-mounted computing devices are managed individually through separate controllers, then device-level control is achieved, but scalability and centralized management become difficult
Solution Approach 1:
The patent applies universality by using the power distribution network as a common communication channel for managing multiple rack-mounted devices. This single infrastructure enables both device-level control and centralized management simultaneously. The power lines provide a universal pathway for transmitting management commands to individual devices while also enabling aggregation of data from all devices through the same network, simplifying scalability and centralized control.
