Abstract
A storage system comprises a disk array enclosure comprising an enclosure controller, a plurality of data storage devices and a plurality of metadata storage devices. The enclosure controller is configured to receive a write operation comprising data to be stored on at least one of the plurality of data storage devices and to determine a logical identifier for the data based at least in part on the received write operation. The enclosure controller is further configured to determine a metadata identifier corresponding to a metadata page stored on the at least one metadata storage device that is associated with the logical identifier and to update the metadata page based at least in part on the metadata identifier. The enclosure controller is further configured to return the logical identifier and the metadata identifier as a response to the received write operation.
