  • On-demand snapshot and prune in a data storage system
    Patent number: 10019183
    Abstract: A method of data progression in a data storage system having at least two tiers of storage space. A first tier may include storage space in a SLC SSD and a second tier may include storage space in a MLC SSD. The method may include setting a predetermined free space threshold for the first tier of storage space, monitoring free space in the first tier of storage space, and when the amount of available free space in the first tier of storage space decreases to the predetermined free space threshold, generating an on-demand snapshot of at least a portion of the data of the first tier of storage space by designating that data as read-only. The on-demand snapshot may then be transferred to the second tier of storage space, thereby freeing the corresponding portion of data of the first tier of storage space for new writes.
    Type: Grant
