A hash value setting unit sets a hash code in data received from a host. Hash code-attached data is stored in a logical volume. A microprocessor unit compares the hash codes for each comparison-targeted data. When hash codes match with one another, a data comparator compares the target data, and determines whether or not the data is duplicated data. When duplicated data is detected, the microprocessor unit removes the duplicated data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage controller and duplicated data detection method using storage controller","description":"A storage controller of the present invention narrows down the target for data comparison by comparing hash codes beforehand and rapidly detects duplicated data.
