The page tier determination program 503 migrates data having a high read access rate out of the pages having a high cache rate to the flash memory drive 204 to a storage tier of the HDD 268, and confirms so that data is not stored in a duplicated manner to the flash memory drive 204 and the SSD 267. Further, the data having a relatively high write access rate is migrated to the storage tier of the SSD 267 so as to prevent deterioration of write process performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Computer system and control method","description":"A computer system according to the present invention is composed of a server 200 having a flash memory drive 204 for cache, a storage system 260 having storage tiers composed of an SSD 267 and an HDD ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9703717","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.
