Abstract:
1. A method of evaluating reliability of flash memory media, the method comprising: measuring 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 the flash memory media group and the flash memory media disks in the flash memory media group, wherein each flash memory media group is one of a RAID group or a thin provisioning pool; obtaining a ratio of sequential to random write I/O types for each flash memory media group; and calculating a remaining life 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, the relationship between said each flash memory media group and the flash memory media disks in said each flash memory media group, and the ratio of sequential to random write I/O types for said each flash memory media group.
