| 发明名称 | Managing file objects in a data storage system | ||
| 摘要 | Managing file objects in a data storage system includes providing a plurality of metadata servers, each metadata server having information for only a subset of file objects in the storage system, each subset for each of the metadata servers being less than a total number of file objects for the system and includes providing at least one metadata location server, where an entity accessing a specific file object of the system determines which of the metadata servers contains data for the specific file object by first accessing the at least one metadata location server. Information for the subset of file objects may include a table having file identifiers and metadata location information. The metadata location information may point to data storage for a metadata object for a file. | ||

| 主权项 | 1. A method of managing file objects in a data storage system, comprising: providing a plurality of metadata servers, each metadata server having information for only a subset of file objects in the storage system, each subset for each of the metadata servers being less than a total number of file objects for the system; and providing at least one metadata location server, different from the metadata servers, wherein an entity accessing a specific file object of the system determines which of the metadata servers contains data for the specific file object by first accessing the at least one metadata location server; wherein the metadata location server assigns a particular one of the metadata servers in connection with creation of a new file object. | ||
