Abstract
This article discusses a novel technique called Hierarchical Bloom Filter Arrays (HBA) to map filenames to the metadata servers holding their metadata.An efficient and distributed scheme for file mapping or file lookup is critical in decentralizing metadata management within a group of metadata servers.Two levels of probabilistic arrays called the Bloom filter arrays with different levels of accuracies, are used on each metadata server. One array, with higher accuracy, caches partial distribution information and exploits the temporal locality of file access patterns whereas the other one with lower accuracy and representing the distribution of the entire metadata has significantly reduced memory overhead. Both arrays are replicated to all metadata servers to support fast local lookups. Here HBA is evaluated through extensive trace-driven simulations and implementation in Linux. HBA design is found to to be highly effective and efficient in improving the performance and scalability of file systems in clusters with 1,000 to 10,000 nodes (or superclusters) and with the amount of data in the petabyte scale or higher .The implementation of HBA can reduce the metadata operation time of a single-metadata-server architecture by a factor of up to 43.9 when the system is configured with 16 metadata servers.
