Level Objective）を明確にし，ユーザとSLA（Service Level

Servicesに基づくインタフェースを提供することでストレージへのアクセスとネットワークの帯域，計算機の同時予約が容易になることと，同時予約を使った応用例を提示して提案システムの有用性を示した．","subitem_description_type":"Other"}]},"item_3_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Performance assurance has become an important aspect in cloud and grid computing where services are provided over the Internet. In particular, the service providers who charge fees for resource usage define Service Level Objective (SLO) and deal with Service Level Agreements (SLA) with users. However, the I/O performance of the storage or data access service is still provided on a best effort basis while computing speed and network bandwidth are often guaranteed. This paper proposes a distributed storage system which guarantees I/O performance to users, by allowing application users to explicitly make an advance reservation for I/O access and storage space, with start and end time of their use. In our proposed architecture, the storage system manages use of disks, I/O paths and etc. based on the reservation, and enforces I/O priorities on the end-to-end path from storage devices to access clients during the reserved time, in order to satisfy the performance requirement. The evaluation result using a prototype implementation indicates that the requested read performance was achieved by this mechanism even when multiple accesses are issued to the storage system simultaneously. In addition, the paper presents that the storage performance can be easily reserved with network bandwidth and computing speed by providing a Web Services based reservation interface, and introduces application use cases of such a combined reservation.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"56","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":"42","bibliographicIssueDates":{"bibliographicIssueDate":"2012-05-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"5"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":82475,"updated":"2025-01-21T18:58:31.427121+00:00","links":{},"created":"2025-01-18T23:36:21.559024+00:00"}
