Abstract
According to one aspect of the invention, a method of evaluating reliability of flash memory media comprises managing a flash memory remaining life for each disk of a plurality of flash memory media disks provided in one or more flash memory media groups each of which has a configuration and a relationship between said each flash memory media group and the flash memory media disks in said each flash memory media group, wherein each flash memory media group is one of a RAID group or a thin provisioning pool; and calculating to obtain information of each flash memory media group based on the measured flash memory remaining life for each disk in said each flash memory media group, the configuration of said each flash memory media group, and the relationship between said each flash memory media group and the flash memory media disks in said each flash memory media group.
