Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage systems, such as SAN and NAS, face limitations in data management due to their inability to effectively handle semantic representation of data, leading to inefficient data access and management capabilities, especially in enterprise environments with high network traffic and bandwidth demands.
Innovation Solution
The implementation of an interposed file access protocol that allows network file operations to be transported over Fibre Channel (FC) and IP networks, minimizing data copies and enabling seamless file access across different protocols and networks, eliminating the need for SAN or NAS boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is stored and managed using traditional SAN or NAS systems, then storage capacity is provided, but data access efficiency deteriorates due to multiple data copying operations and protocol boundaries
Solution Approach 1:
The patent introduces an intermediary translation layer that converts between Fibre Channel protocols and IP-based network protocols. This mediator enables direct file access over FC networks without requiring multiple data copies between different storage architectures, thereby improving data access efficiency and reducing time loss.
Solution Approach 2:
The system provides universal file access capabilities across multiple network types (Fibre Channel, IP networks, Data Center Ethernet) through a unified protocol translation approach. This multi-functionality eliminates the need for separate SAN and NAS boundaries, allowing efficient data access regardless of the underlying network infrastructure.
2Adaptability or versatility
If protocol boundaries between SAN and NAS are maintained, then system architecture is simplified, but file access capability across different networks deteriorates
Solution Approach 1:
The patent employs protocol translation intermediaries that handle the complexity of multi-protocol support. These intermediaries translate between Fibre Channel and IP-based protocols, enabling versatile file access across different networks while shielding users from the underlying protocol complexity.
Solution Approach 2:
The system creates virtual copies of file access interfaces that work across different network protocols. By implementing file access protocols that can be transported over both FC and IP networks, the system provides consistent file access capabilities without requiring users to understand the underlying protocol differences.
3Adaptability or versatility
If additional volume managers or file systems are implemented to enable cross-network file access, then file access versatility is improved, but system complexity and resource requirements worsen
Solution Approach 1:
The patent implements a universal file access protocol that works across Fibre Channel, IP networks, and Data Center Ethernet without requiring additional volume managers or file systems. This multi-functional approach provides cross-network file access while maintaining system simplicity by eliminating the need for multiple specialized components.

AI summary
Disclosed are methods and apparatus for facilitating transmission of file access type messages over a Fiber Channel (FC) network. In one embodiment, at a file interposed access protocol layer of a file access client, a file access type operation is received from a file access type layer at the client device. The interposed layer may be interposed between an upper file access layer and an FC layer. The file access type operation specifies a request pertaining to file access. At the interposed file access protocol layer of the client, the file access type operation is modified into one or more sequence of operations so that the operations can be transmitted over an FC network. A sequence of operations are transmitted to an file access server over the FC network.
