According to one embodiment, a metadata management system (MDS) may include partitioned migratable metadata. Metadata may be stored in multiple metadata partitions (102-0 to 102-11). Each metadata partition may be assigned to a particular system resource (104-0 to 104-5). According to predetermined policies, such as metadata aging, metadata stored in one metadata partition may be migrated to a different metadata partition. A forwarding object can be placed in the old metadata partition to indicate the new location of the migrated metadata. Metadata partitions (102-0 to 102-11) may be reassigned to different resources, split and/or merged allowing a high degree of scalability, as well as flexibility in meeting storage system needs.

The present invention relates generally to data storage systems, and more particularly to a high capacity storage systems that include metadata corresponding to stored files.
The demand for high-capacity data storage systems continues to rise. As the interconnection of data networks continues, there is an increasing demand to store very large numbers of files in an efficient fashion while at the same time enabling such a storage system to grow as the number of files increases.
While various conventional data storage systems are known, such approaches have not always been efficient, easy to scale, or cost effective. Conventionally, data storage systems have resided on a monolithic server. A monolithic server can be conceptualized as including a single, very powerful computing resource dedicated to accessing files that may be stored on a variety of media. Such a monolithic server can maintain a collection of metadata for the stored files.
FIG. 1 is a block diagram of a metadata management system (MDS) according to one embodiment of the present invention.
FIG. 2 is a diagram illustrating a file system according to one embodiment of the present invention.
FIGS. 3A to 3C are block diagrams illustrating various operations that may be performed in a MDS according to the embodiment of FIG. 1.
Various embodiments of the present invention will now be described in conjunction with a number of diagrams. The various embodiments include a system for managing metadata stored on different partitions. Such a system can allow for easy and cost-effective scaling and/or allow for the migration of metadata according to aging or other criteria. Further, the present invention may allow for easier or more effective management of large amounts of metadata as partitions can be added, split or merged as needed.
As noted above, conventional file storage systems have typically stored file metadata on a single partition. According to the present invention, a metadata management system may include metadata that may be distributed over multiple partitions.
