    Abstract: In a method for controlling data stored in an Solid State Disk (SSD) of a data de-duplication system, a storage controller obtains stability information of a data block. The stability information comprises a reference count of the data block and a length of a period of time when the data block is stored in the SSD. The storage controller identifies a stability level of the data block according to the stability information, and sends the stability level of the data block to the SSD. The SSD moves the data block to a target block which corresponds to the stability level. Thereby, the SSD can store data blocks having a same stability level together.

    Abstract translation: 在用于控制存储在重复数据删除系统的固态盘(SSD)中的数据的方法中,存储控制器获得数据块的稳定性信息。 稳定性信息包括数据块的参考计数和数据块存储在SSD中的时间段的长度。 存储控制器根据稳定性信息识别数据块的稳定性级别,并将数据块的稳定性级别发送到SSD。 SSD将数据块移动到对应于稳定性级别的目标块。 因此,SSD可以将具有相同稳定性水平的数据块存储在一起。
