Publication number: 20220237151Abstract: A method for implementing a storage system is described. The method includes accepting a filepath from a user that specifies a file. The method includes forming a primary key for a representation of the file. The method includes applying the primary key to a database cloud service to obtain a representation of the file. The representation of the file includes an inode for the file's meta data. The method includes using the inode for the file's meta data to obtain the file's meta data from a high performance object cloud storage service. The file's meta data points to information within the high performance object cloud storage service for accessing the file's stripes. The method includes accessing the information within the high performance object cloud storage service to obtain an object ID for a stripe within the file. The method includes using the object ID to access the stripe from a low performance object cloud storage service.Type: ApplicationFiled: January 22, 2021Publication date: July 28, 2022Inventors: Giorgio REGNI, Vianney RANCUREL, Nicolas TRANGEZ

Publication number: 20190073395Abstract: A method is described. The method includes receiving a request to search meta data for objects stored within a large scale object storage system. The request identifies a looked for value of the meta data. The objects belong to a same bucket used to identify a subset of objects stored by the large scale object storage system. The method includes forwarding the request to a meta data database system that contains pages listing all objects within the bucket and the associated meta data for each of the objects within the bucket.
