Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server architectures require extensive cabling for I/O connectivity, leading to inefficiencies, management complexities, and inflexibility, especially in large data centers, and existing virtualization methods still rely on significant cabling and complex cable management.
Innovation Solution
Implementing wireless virtualized I/O controllers, such as virtual Network Interface Cards (vNICs) and virtual Host Bus Adapters (vHBAs), that use reliable communication protocols over wireless networks to provide I/O connectivity to hosts, eliminating the need for physical cables and enabling flexible resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple I/O resources (NICs, HBAs) are provided in each server for redundancy and fault tolerance, then connectivity and reliability are improved, but cabling requirements and system complexity increase significantly
Solution Approach 1:
The patent implements an I/O director that consolidates multiple I/O resources (NICs, HBAs) into a single shared device. This director provides multi-functionality by handling network I/O, storage I/O, and other peripheral operations through a unified interface, eliminating the need for multiple dedicated I/O cards in each server and dramatically reducing cabling complexity while maintaining fault tolerance through virtualized resource allocation
Solution Approach 2:
The I/O director acts as an intermediary between servers and external I/O devices. It virtualizes I/O resources and manages all connections to external networks and storage systems, serving as a mediator that consolidates multiple connection paths into a single point of interface while maintaining the redundancy and fault tolerance capabilities through software-based resource management
2Adaptability or versatility
If an I/O director is used to virtualize I/O resources, then resource sharing and fault tolerance are improved, but significant cabling and cable management complexity remain
Solution Approach 1:
The patent extracts the cabling requirement entirely from the system by implementing wireless communication between servers and the I/O director. The I/O director maintains its resource virtualization and sharing capabilities while eliminating physical cable connections, thereby removing cable management complexity completely while preserving adaptability and versatility of resource allocation
Solution Approach 2:
The patent replaces the mechanical cabling system with wireless communication technology. Instead of using physical cables to connect servers to the I/O director, the system employs wireless protocols to transmit I/O data, thereby substituting a mechanical connection system with a wireless communication system that maintains functionality while eliminating physical infrastructure complexity
3Reliability
If conventional I/O architectures are used with multiple cables per server, then connectivity is provided, but the system becomes rigid and reconfiguration is inflexible
Solution Approach 1:
The patent implements dynamic I/O resource allocation through wireless communication and software-based virtualization. The I/O director can dynamically assign and reassign I/O resources to different servers based on changing requirements, and the wireless connection allows for easy reconfiguration without physical cable changes, making the system highly adaptable while maintaining reliable connectivity through protocol-level error correction and redundancy

AI summary
Mechanisms provide hosts such as servers and mobile devices with access to virtualized I/O resources including virtual Host Bus Adapters (vHBAs) and virtual Network Interface Cards (vNICs) over a wireless I/O interconnect. Host applications access virtualized I/O resources using virtual device drivers that communicate with virtualized I/O resources on an I/O director using a reliable communication protocol running over a wireless network. I/O data is throttled if necessary based on wireless network considerations.
