Abstract
A system and method for metadata storage includes use of a storage controller to receive a write operation from a host, create a metadata entry for storing metadata associated with data written by the write operation, and store the metadata entry into a metadata store. The metadata store includes a plurality of active partitions, a plurality of inactive partitions, and a queue identifying locations in the active partitions where the metadata entry may be stored. The metadata store is further used to access data written to one or more storage devices. Storing the metadata entry into the metadata store includes popping a first location from the queue, identifying a first active partition from the active partitions based on the first location, and storing the metadata entry in the first active partition. In some embodiments, each of the active partitions may be organized into two or more tiers.
