The same virtual identifier is set for a volume of the first storage unit and for a volume of the second storage unit. The path control unit of the host identifies a plurality of volumes which have the same virtual identifier as one virtual volume. A remote copy pair can also be set by a virtual volume and a volume of the third storage unit. The setting of the virtual volume and the setting of the remote copy can be performed by means of an instruction from the management server."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage system and virtualization method","description":"The storage system of the present invention is able to generate one virtual logical device from different logical devices which exist in each of the different storage control units and remote-copy all","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9619171","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
