NAS Metadata Editing via Periodic Batching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage systems, particularly Network-Attached Storage (NAS) devices, face performance degradation and reduced lifespan when editing metadata for frequently modified data objects, as frequent access to different storage components increases wear and slows down data copying processes.
Innovation Solution
Implementing a metadata editing mechanism that uses a queue of storage locations, a list of data objects, and timed periods to batch and combine metadata edits, ensuring timely updates without frequent access, thereby improving performance and extending the life of the NAS device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metadata is updated immediately after each data object modification, then data consistency is maintained, but device performance degrades and lifespan reduces
Solution Approach 1:
The patent implements periodic metadata updates by introducing a time threshold mechanism. Instead of updating metadata immediately after every data object modification, the system accumulates modifications and updates metadata periodically when the time threshold is reached or the number of modified objects exceeds a threshold. This periodic action reduces the frequency of metadata updates while still maintaining data consistency, thereby improving device performance and extending lifespan.
Solution Approach 2:
The patent applies preliminary action by pre-defining thresholds for metadata updates (time threshold and object count threshold). These pre-established criteria allow the system to batch multiple data object modifications together and update metadata only when necessary, rather than reacting to each individual modification. This preliminary setup enables efficient resource management and reduces unnecessary write operations to the storage device.
2Reliability
If metadata is updated frequently to maintain consistency, then data security is improved, but wear on storage components increases
Solution Approach 1:
By implementing periodic metadata updates based on time thresholds and object count thresholds, the system reduces the frequency of write operations to storage components. This periodic approach maintains data security through regular consistency checks while significantly reducing wear on storage components, thereby extending the operational lifespan of the NAS device.
Solution Approach 2:
The patent applies partial action by updating metadata only when necessary (when thresholds are met) rather than after every single modification. This selective updating approach maintains sufficient data consistency for security purposes while minimizing unnecessary write operations that would contribute to component wear and reduce device lifespan.
3Duration of action of stationary object
If metadata updates are batched to reduce access frequency, then device lifespan is extended, but update timeliness may be delayed
Solution Approach 1:
The system uses periodic action with dual thresholds (time threshold and object count threshold) to balance lifespan extension with update timeliness. The time threshold ensures that metadata is updated within a reasonable time frame, preventing excessive delays, while the object count threshold allows batching to reduce access frequency. This dual-threshold periodic approach extends device lifespan while maintaining acceptable update timeliness.
Solution Approach 2:
The patent implements dynamics by making the metadata update mechanism adaptive through configurable thresholds. The system can adjust the time threshold and object count threshold based on workload conditions, allowing it to be more aggressive during low-activity periods (extending lifespan) and more responsive during high-activity periods (reducing delays). This dynamic adjustment optimizes both device lifespan and update timeliness.

AI summary
Systems and methods are disclosed for editing metadata for data objects on a data storage device, which may be configured to identify data objects that have been modified and may be associated with storage locations of a file system. The data storage device may also be configured determine whether a first period of time has elapsed and may further be configured to determine whether a second period of time has elapsed or whether a threshold number of data objects in the file system have been modified in response to a first determination that the first time period has elapsed. The data storage device may further be configured to edit a set of metadata for a set of data objects in response to a second determination that the second period of time has elapsed or the threshold number of data objects in the file system have been modified.
