The invention discloses a heterogeneous storage system and a data storage center, wherein the heterogeneous storage system and the data storage center belong to the field of data storage technology. The system comprises the components of a secondary memory which is composed of at least one kind of low-rotating-speed hard disk drives; a high-grade memory which is composed of at least one kind of high-performance memories; a counting unit which is connected with the secondary memory and the high-grade memory and is used for counting the transmission condition of data that are stored in the secondary memory in a preset time period and outputting; and a control unit which is connected with the counting unit, the secondary memory and the high-grade memory and is used for transferring the data in the secondary memory into the high-grade memory according to the transmission condition that is output from the counting unit. The heterogeneous storage system and the data storage center have beneficial effects of realizing intelligent power consumption management of large-scale inactive magnetic disk array, and improving operation stability and reliability of the magnetic disk drives.
Description
technical field [0001] The invention relates to the technical field of data storage, in particular to a heterogeneous storage system and a data storage center. Background technique [0002] Compared with SSD (Solid State Drives, solid state drive), although HDD (Hard Disk Drive, mechanical hard disk) has higher power consumption and greater access delay, it is because of its lower price and longer service life HDD is still widely used in data centers that need to store massive (such as EB or YB) data. [0003] However, due to the characteristics of HDD itself, the internal disk must rotate at a high speed to make it work normally. The rotation of the disk is driven by an internal motor. The higher the RPM (Revolutions Per Minute, the revolution per minute), the greater the power consumption required. The relationship between disk speed and power consumption is as follows: figure 1 shown in . It is precisely because of the huge demand for HDDs in data centers that the disk...
