Verfahren zum Gebrauch von Speicherplatten unterschiedlicher Inhalte in einem Einzelvolumen einer hierarchischen Speicherplattenanordnung

摘要

The method concerns fully utilizing storage capacity in a heterogenous hierarchic disk array (10) having storage disks (12) of differing capacities. The disks (12) are segmented into multiple regions (35). The method fully utilizes of storage capacity by configuring the heterogeneous disk array to employ a minimum of two equal-sized storage disks that have larger capacity than other individual storage disks in the disk array. The contiguous regions across the multiple disks are then grouped together to form the RAID areas.
