BIN-LESS METADATA PAGES ALLOCATOR FOR STORAGE CLUSTER WITH LOG-STRUCTURED METADATA - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240338322 titled 'BIN-LESS METADATA PAGES ALLOCATOR FOR STORAGE CLUSTER WITH LOG-STRUCTURED METADATA
The patent application discusses techniques for creating a "bin-less" metadata page allocator for clustered systems with log-structured metadata storage.
- The techniques involve using a mapping structure in memory of a storage node to map logical addresses of metadata pages to physical addresses of storage drives within a storage array.
- A translation table is utilized to translate logical addresses of metadata pages to corresponding current physical addresses of storage drives.
- When a logical address of a metadata page is no longer in use, its corresponding current physical address is replaced with a predefined value in the translation table, freeing the logical address and inserting it into a free logical address array.
- Freed logical addresses are allocated from the free logical address array.
Potential Applications: - Data centers - Cloud storage systems - Distributed file systems
Problems Solved: - Efficient allocation of metadata pages in clustered systems - Optimizing storage space and performance
Benefits: - Improved storage management - Enhanced system performance - Reduced storage overhead
Commercial Applications: The technology can be applied in various commercial settings such as data centers, cloud storage providers, and companies utilizing distributed file systems. It can help improve storage efficiency and performance in large-scale storage environments.
Questions about the technology: 1. How does the mapping structure in memory optimize the allocation of metadata pages? 2. What are the key advantages of using a log-structured metadata storage system in clustered environments?
Original Abstract Submitted
techniques for providing a “bin-less” metadata page allocator for clustered systems with log-structured metadata storage. the techniques include providing a mapping structure in memory of a storage node of a clustered system. the mapping structure can have multiple layers configured to map logical addresses of metadata pages to physical addresses of storage drives within a storage array. the techniques include providing a translation table configured to translate logical addresses of metadata pages to corresponding current physical addresses of storage drives within the storage array. the techniques include, in response to an allocated logical address of a metadata page no longer being in-use, replacing its corresponding current physical address with a predefined value in the translation table, freeing the logical address, and inserting the freed logical address into a free logical address array. the techniques include allocating the freed logical address from the free logical address array.
