Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional file systems face inefficiencies in processing and resource usage when generating short filenames across different naming protocols, particularly in large directories, due to collision checking and resource-intensive operations.
Innovation Solution
A naming scheme that utilizes a unique numeric identifier associated with a particular naming protocol to generate short filenames, eliminating the need for collision checking and resource usage by leveraging an existing unique identifier for deterministic name generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional collision checking is performed to generate unique M83 filenames, then filename uniqueness is ensured, but processing time and computational resources increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-computing and storing the mapping between long filenames and their corresponding M83 filenames in a hash table during file creation. This allows the system to avoid collision checking during filename generation, as the unique M83 filename is determined directly from the pre-stored mapping, resolving the contradiction between ensuring uniqueness and reducing processing time
Solution Approach 2:
The patent uses copying by creating a deterministic copy of the long filename through a hash function that always produces the same M83 filename for a given long filename. This deterministic copying eliminates the need for collision checking while ensuring uniqueness, as the same input always yields the same unique output
2Reliability
If conventional collision checking is performed to generate unique M83 filenames, then filename uniqueness is ensured, but computational resource consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-computing and storing the mapping between long filenames and their corresponding M83 filenames in a hash table during file creation. This allows the system to avoid collision checking during filename generation, as the unique M83 filename is determined directly from the pre-stored mapping, resolving the contradiction between ensuring uniqueness and reducing processor resource consumption
Solution Approach 2:
The patent replaces the mechanical collision checking process with a deterministic hash function that directly computes the M83 filename from the long filename. This substitution eliminates the need for iterative collision detection and resolution, significantly reducing computational resource consumption while maintaining filename uniqueness
3Adaptability or versatility
If M83 filenames are stored in the directory, then filename compatibility is achieved, but disk space is consumed that could be used for file contents
Solution Approach 1:
The patent extracts the M83 filename from the directory entry storage and computes it on-demand from the long filename using a deterministic hash function. This extraction eliminates the need to store M83 filenames in the directory, freeing up disk space for file contents while maintaining filename compatibility through deterministic computation
Solution Approach 2:
The patent uses copying by creating a deterministic copy of the long filename through a hash function that produces the M83 filename only when needed. This on-demand copying eliminates the need to store M83 filenames permanently in the directory, reducing disk space consumption while maintaining adaptability across different naming protocols
4Reliability
If directory searching is performed to check for filename collisions, then filename uniqueness is ensured, but the operation becomes unwieldy and resource-intensive in large directories
Solution Approach 1:
The patent applies preliminary action by pre-computing and storing the mapping between long filenames and their corresponding M83 filenames in a hash table during file creation. This allows the system to avoid collision checking during filename generation, as the unique M83 filename is determined directly from the pre-stored mapping, resolving the contradiction between ensuring uniqueness and reducing search operation complexity
Solution Approach 2:
The patent replaces the mechanical directory searching process with a deterministic hash function that directly computes the M83 filename from the long filename. This substitution eliminates the need for iterative collision detection and resolution through directory searching, significantly reducing operational complexity while maintaining filename uniqueness

AI summary
An improved technique involves providing a naming scheme that uses a unique numeric identifier associated with a particular naming protocol. Along these lines, when a storage processor receives a first name of a file that conforms to a first naming protocol, the storage processor places the first name and an inode number corresponding to the file in a directory entry. The storage processor associates this entry with a unique numeric identifier by which the entry can be located within the directory. Based on this unique identifier, the storage processor is configured to generate the second name that conforms to the second naming protocol.
