Among the plurality of control units, a main control unit that controls the migration of a migration source virtual volume selects, as a migration destination storage apparatus, one storage apparatus connected to an access path from which was obtained a second measured value, which is a measured value that is smaller than a first measured value indicating a latency in an access path connecting a migration source storage apparatus, which includes the migration source virtual volume, and the server, and indicates a latency in an access path connecting a storage apparatus, other than the migration source storage apparatus, and the server, and allocates a migration destination virtual volume in the migration destination storage apparatus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Computer system","description":"A computer system includes a server that issues an access request with a virtual volume among the plurality of virtual volumes allocated in a plurality of storage apparatuses as an access target and m","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9680933","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.
