Multi-Tiered Metadata Scheme for a Data Storage Array |
摘要 |
Method and apparatus for managing metadata associated with a data storage array. In accordance with various embodiments, a group of user data blocks are stored to memory cells at a selected physical address of the array. A multi-tiered metadata scheme is used to generate metadata which describes the selected physical address of the user data blocks. The multi-tiered metadata scheme provides an upper tier metadata format adapted for groups of N user data blocks, and a lower tier metadata format adapted for groups of M user data blocks where M is less than N. The generated metadata is formatted in accordance with a selected one of the upper or lower tier metadata formats in relation to a total number of the user data blocks in the group.
