Abstract
A storage management method, includes steps: detecting sizes of shared storage spaces of all terminal devices joined in a sharing system; dividing the all terminal devices into a number of device groups randomly; classifying the terminal devices of each group into a number of kinds of terminal devices according to the sizes of the shared storage spaces of the terminal devices of each device group; mapping the shared storage spaces of each kind of terminal device of each device group to one corresponding virtual disk of one row of a virtual disk array card; and determining a size of a file to be stored when receiving a storing request, and selecting a virtual disk with size nearest to and greater than or equal to that of the file from one row randomly, and storing the file into the terminal devices mapping to the selected virtual disk.
