[Abstract] The low-power-consuming cStor cloud storage system comprises software and hardware. Software is used to manage storage hardware, and even though this hardware consumes little power, it is still reliable and highly available. With cStor, the cost of storage power can be reduced. The motherboards of the storage devices, which are based on ARM chips, consume less than 5 W, and a single node can support up to 16 SATA HDDs. In the standard 42U rack, cStor can support up to 1152 TB storage capacity and consume only 3400 W of power.
