Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and assembling server farms, particularly those with diskless servers, is complicated due to the need for automated IP address assignment and unified operating system management across multiple servers.
Innovation Solution
A system comprising an operating system builder, an operating system image manager, and a run-time configuration and management tool that creates a binary image for diskless servers, enabling automated operation, high-availability management, and security protocols, with tools for managing and monitoring server health and IP configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If diskless servers are used to simplify hardware and improve scalability, then device complexity and storage requirements are reduced, but the difficulty of assembling and managing the server farm increases due to automated IP address assignment and operating system management requirements
Solution Approach 1:
The patent introduces an intermediary system comprising a management server and automated provisioning software that mediates between the diskless servers and the network infrastructure. This intermediary handles IP address assignment, operating system image deployment, and configuration management, thereby resolving the management difficulty while preserving the hardware simplicity of diskless servers.
Solution Approach 2:
The patent implements self-service mechanisms where diskless servers automatically obtain IP addresses through DHCP, retrieve operating system images via TFTP, and execute automated installation scripts. This self-service approach eliminates manual configuration requirements and enables servers to provision themselves, resolving the management difficulty while maintaining hardware simplicity.
2Productivity
If automated operating system image management is implemented across multiple servers, then productivity and deployment efficiency are improved, but the device complexity and security management requirements increase
Solution Approach 1:
The patent implements a universal management architecture where a single management server and software suite handle multiple functions including IP address assignment, operating system image storage and distribution, configuration management, and security enforcement across all diskless servers. This multi-functional approach improves deployment efficiency while consolidating complexity into a centralized system rather than distributing it across individual servers.
3Ease of operation
If a unified operating system image is deployed across multiple diskless servers, then ease of operation and consistency are improved, but the adaptability to different server configurations and requirements decreases
Solution Approach 1:
The patent segments the operating system image into modular components including a base image containing common system files and configuration, and separate configurable parameters that can be customized for different server roles. The automated provisioning system selectively applies different configuration sets to the base image depending on the server's intended function, thereby maintaining ease of unified management while preserving configuration flexibility for different server requirements.
Data Source
AI summary
A system controls operating system images for a group of diskless servers and comprises an operating system builder, an operating system image manager and a run-time configuration and management tool. The operating system builder is configured to create a binary image of an operating system and modify components of the image by automated operation. The binary image is operative as common base operating system image for multiple servers. The operating system image manager discovers and manages a set of diskless servers in conjunction with a server manageability interface and a boot server. The run-time configuration and management tool for the diskless server set is configured for high-availability management, server and application health monitoring, and enforcing a security protocol between a network and a host server and individual diskless servers.
