  • Control of storage of data in a hybrid storage system
    Patent number: 10671290
    Abstract: Example control methods of hybrid storage are provided, which are applied to each HDD-type storage device and each SSD-type storage device in a storage system having one or more HDD-type storage devices and one or more SSD-type storage devices. Each HDD-type storage device in the storage system is connected to the SSD-type storage device. Each HDD-type storage device and each SSD-type storage device stores one or more data blocks respectively. Access information of each data block stored in a storage device is periodically acquired. A storage location of each data block in the storage system is adjusted according to the acquired access information of each data block. By using the technical solution of the present disclosure, the storage location of the data block is dynamically configured according to an access frequency so that advantages of different storage devices are fully utilized.
