摘要
The system receives a request to write data and associated metadata. The system determines a key associated with the data, wherein the key corresponds to an entry in a data structure maintained by a first storage system. The system writes the metadata to a first non-volatile memory of a first set of storage drives of the first storage system by updating the entry with a logical block address for the data and a physical location in a second set of storage drives of a second storage system. The system writes the key and the data to a second non-volatile memory of the second set of storage drives based on the physical location, wherein the first non-volatile memory is of a lower density than the second non-volatile memory.
