Abstract
Provided are an apparatus and method for managing data storage. A first log structured array stores data in a storage device. A second log structured array in the storage device stores metadata for the data in the first log structured array, wherein the second log structured array storing the metadata for the first log structured data storage system is nested within the first log structured array, and wherein the first and second log structured arrays comprise separate instances of log structured arrays. Address space is allocated in the second log structured array for metadata when the allocation of address space is required for metadata for data stored in the first log structured array.
