Embodiments of the present invention disclose a data storage method and a storage server, where the method includes: detecting actual usage of a hard disk corresponding to an initial capacity level in configured hard disk capacity levels, where the hard disk capacity levels are obtained by means of classification according to an actual hard disk capacity; when it is determined, according to the detected actual usage, that the hard disk corresponding to the initial capacity level exceeds a limit, searching for a hard disk corresponding to a second highest capacity level that is in the configured hard disk capacity levels and is higher than the initial capacity level; and when the hard disk corresponding to the second highest capacity level is obtained by means of searching, determining a migration ratio of a virtual node according to the initial capacity level, the second highest capacity level, and the actual hard disk capacity, and performing, according to the migration ratio, virtual node migration between hard disks that are corresponding to the configured hard disk capacity levels, where the virtual node carries stored data. By using the present invention, hard disk capacity heterogeneousness in massive storage can be supported. |
