Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in efficiently managing keyboard, video, and mouse (KVM) functionality across multiple server modules, particularly in constrained environments with limited computing resources, limiting the range of server modules that can be accessed remotely and affecting real-time tasks like video processing.
Innovation Solution
An enclosure controller utilizing a network interface to server module baseboard management controllers (BMCs) enables virtual KVM sessions, decompresses video data, and dynamically adjusts processing parameters such as frame refresh rate and compression levels to manage processing burdens, allowing KVM capability extension beyond local chassis to remote servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hardware dedicated to local KVM capability is used in previous modular servers, then local keyboard, video, and mouse functionality is achieved, but device complexity increases and resource utilization decreases
Solution Approach 1:
The patent implements a universal KVM controller that can be shared across multiple server modules through a network interface. Instead of dedicating separate USB MUXes, USB hubs, USB redrivers, VGA MUXes, VGA switches, and VGA redrivers to each server module, a single KVM controller provides keyboard, video, and mouse functionality to multiple servers remotely, eliminating redundant hardware and reducing overall system complexity
Solution Approach 2:
The patent introduces a network interface as an intermediary between the KVM controller and server modules. This allows KVM functionality to be transmitted over the network rather than requiring direct physical connections through dedicated hardware, enabling remote access to multiple servers from any location while reducing the need for local hardware at each server module
2Productivity
If one KVM is used to interact with a selected server module, then resource utilization improves, but the range of accessible server modules is limited to local chassis
Solution Approach 1:
The patent extends KVM accessibility from a single local chassis to a network-wide dimension by implementing remote server module discovery and selection capabilities. The KVM controller can discover server modules across the network, display them in a user interface, and switch between them remotely, transforming the KVM system from a localized device into a network-wide management tool that can access servers in different locations and data centers
Solution Approach 2:
The KVM controller is designed to provide universal access to multiple server modules across the network, not just within a single chassis. The system can discover, manage, and switch between server modules from different locations through the network interface, making the KVM functionality adaptable to various deployment scenarios including remote data centers and distributed server environments
3Speed
If video processing is performed in constrained environments with limited computing resources, then real-time video processing is achieved, but processing performance deteriorates
Solution Approach 1:
The patent extracts video processing functions from the constrained embedded processor environment and relocates them to more powerful remote servers or dedicated video processing units. The embedded processor captures and transmits video data over the network, while heavy processing tasks like video decoding, compression, and rendering are performed on remote systems with greater computational resources, allowing real-time video processing without overloading the constrained embedded processor
Solution Approach 2:
The network interface acts as an intermediary that enables video data to be transmitted from the embedded processor to remote processing systems. This allows the embedded processor to focus on capture and transmission while leveraging remote resources for intensive video processing tasks, effectively extending the processing capability beyond the constraints of the embedded environment
