摘要
A storage system in one embodiment comprises a plurality of storage devices and a storage controller. The storage controller is configured to receive information indicating whether target data is one of a non-deduplicatable type of data and a deduplicatable type of data. Responsive to the information indicating that the target data is of the deduplicatable type, the storage controller is configured to utilize a content-based mapping generated based on a content of the target data to identify a corresponding physical address for storing the target data. Responsive to the information indicating that the target data is of the non-deduplicatable type, the storage controller is configured to utilize an address-based mapping generated based on a logical address associated with the target data to identify a corresponding physical address for storing the target data.
