An integrated cache management function in the computer arbitrates which computer or virtual machine should cache the data of the secondary storage device, and when the computer or the virtual machine executes input/output of data of the secondary storage device, the computer inquires the integrated cache management function, based on which the integrated cache management function retains the cache only in a single computer, and instructs the other computers to delete the cache. Thus, it is possible to prevent identical data from being cached in a duplicated manner in multiple locations of the primary storage device, and enables efficient capacity usage of the primary storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage device and computer system","description":"When computers and virtual machines operating in the computers both attempt to allocate a cache regarding the data in a secondary storage device to respective primary storage devices, identical data i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9766824","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.
