AVOIDING RAID ARRAY OVERDRIVE USING NONVOLATILE MEMORY IN CACHE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240134530 titled 'AVOIDING RAID ARRAY OVERDRIVE USING NONVOLATILE MEMORY IN CACHE
Simplified Explanation
The abstract describes a method for managing overdrive in a RAID array by selecting an extent residing in both the overdriven RAID array and a cache, staging missing data from the overdriven array to complete the extent in the cache, freeing space in the original array, destaging the extent data to a target RAID array, and freeing space in the cache.
- Detect overdrive of a RAID array
- Select an extent in both the overdriven RAID array and a cache
- Stage missing data from the overdriven array to complete the extent in the cache
- Free space in the original array
- Destage the extent data to a target RAID array
- Free space in the cache corresponding to the extent
Potential Applications
This technology could be applied in data storage systems to efficiently manage overdrive situations in RAID arrays.
Problems Solved
1. Efficiently managing overdrive situations in RAID arrays 2. Optimizing data storage and retrieval processes
Benefits
1. Improved performance and reliability of RAID arrays 2. Enhanced data management capabilities 3. Increased efficiency in data storage operations
Potential Commercial Applications
Optimizing data storage systems for businesses Improving data management in cloud storage services
Possible Prior Art
Prior art related to optimizing data storage systems and managing RAID arrays efficiently may exist, but specific examples are not provided in the abstract.
Unanswered Questions
How does this method impact overall system performance?
The abstract does not provide details on the potential impact of this method on the overall performance of the system.
Are there any limitations to the scalability of this method?
It is unclear from the abstract whether there are any limitations to the scalability of this method in larger RAID arrays or complex storage systems.
Original Abstract Submitted
in one general embodiment, a computer-implemented method includes detecting overdrive of a raid array. an extent residing, at least in part, in both the overdriven raid array and in a cache is selected. data missing from the extent is staged, from the overdriven raid array, to complete the extent in the cache. the original extent space in the overdriven raid array is freed. the extent data in the cache is destaged to a target raid array. space in the cache corresponding to the extent is freed in response to completing the destaging.
