摘要：
The present invention creates a pool comprising tiers corresponding to the performance of logical volumes.A first storage apparatus either acquires or measures the performance of multiple external pool volumes of an external storage (S1711 through S1714), and creates a pool volume group based on the performance of the external pool volumes (S1715, S1716). The rank order of a tier is decided in accordance with the performance of each pool volume group (S1717, S1718). This makes it possible to relatively easily create a pool comprising multiple appropriate tiers that are suited to the current situation.
