Storage virtualization, however, hides the physical resources of storage form applications and makes difficult to solve I/O performance problem. To solve this problem, we developed an I/O performance monitor which can visualize the detail of I/O response time and I/O count of storage resource by DBMS data and SQL. We also evaluated by solving the storage performance problem of DBMS which uses virtualized storage by using this technology. As a result, we confirmed that our approach could find a DB data placement confliction in storage RAID group. We also confirmed that out approach could provide a new troubleshooting method, and reduce the I/O performance troubleshoot time.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"40","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"28","bibliographicIssueDates":{"bibliographicIssueDate":"2008-12-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"1"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
