In a case where the storage apparatus receives a write request comprising write-destination information for identifying a write-destination virtual area in the virtual volume, and, in addition, the write-destination virtual area is an unallocated virtual area, the storage apparatus selects a medium, which corresponds to the write to the write-destination virtual area and/or the identification information of the source of this write, from a plurality of media, which have different performances and which are each configured from two or more real areas, and allocates a real area from the selected medium to the write-destination virtual area."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for controlling data write to virtual logical volume conforming to thin provisioning, and storage apparatus","description":"The virtual volume is a virtual logical volume that conforms to Thin Provisioning, and is a logical volume configured from a plurality of virtual areas and used by a plurality of applications.
