KVM Redirection Module for Remote Server Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote management solutions for computer networks require physical presence and are cumbersome, especially for managing multiple computers, as they rely on software-based systems that do not allow configuration and boot-up screens to be accessed remotely, and hardware-based solutions increase clutter and signal degradation.
Innovation Solution
A KVM redirection module with a printed circuit board, frame grabber, network interface, and processing device that captures video signals from local computers, allowing remote monitoring and control through a network, reducing the need for physical presence and minimizing clutter and signal issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software-based remote management solutions are used, then remote monitoring capability is provided, but configuration and boot-up screens cannot be accessed and the operating system must be operational
Solution Approach 1:
A KVM redirection module is introduced as an intermediary device between the local computer and the remote management system. This module captures video signals at the hardware level before they reach the computer's display output, and redirects them over the network to a remote display device. This hardware-level interception allows access to all screen content including BIOS configuration screens and boot-up sequences, regardless of the operating system's operational state.
2Ease of operation
If hardware-based remote management devices are connected to each local computer, then remote management capability is provided, but cable clutter increases and signal degradation occurs
Solution Approach 1:
Multiple KVM redirection modules are consolidated into a single networked architecture where multiple local computers connect to a centralized KVM switch or hub, which then connects to a single remote management station. This merging reduces the number of individual connections needed, minimizes cable clutter at each local computer, and prevents signal degradation by using standardized network protocols for transmission.
3Productivity
If multiple external remote management devices are connected via network, then remote management of multiple computers is enabled, but the number of cables and connectors increases
Solution Approach 1:
The KVM redirection module is designed with universal connectivity capabilities, supporting multiple local computer connections through a single device or hub. The module can manage multiple video signals, keyboard inputs, and mouse commands simultaneously, allowing one remote management station to control numerous local computers without requiring separate external management devices for each computer.

AI summary
Apparatus, methods, and systems provide for remote management of a set of local computers by transferring screen frames produced by the local computer for viewing at a remote computer. A redirection module captures and transmits video signals from a local computer through over a network, such as the Internet, to a remote computer where the remote computer produces a display that contains the screen frames being transferred. The module is configured for use with and installation within a keyboard, video, and mouse switch configured for receiving the module. The redirection module is further configured for use with and installation on a server-blade to allow remote management of the server-blade.
