By storing and analyzing such large amounts of data for a long period of time, there is a growing movement to create new value. Highly reliable and low-cost tape storage is attracting attention as a basis for realizing it. Erasure coding is available as a redundancy means for further reducing the TCO of the tape storage, but there is a problem that the access efficiency is deteriorated in the conventional method depending on the data size due to the large latency peculiar to the tape. In this research, we propose a method that can be accessed with high efficiency by switching the optimal EC method according to the data size.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2020-02-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2020-SLDM-191"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":203296,"updated":"2025-01-19T20:35:56.168260+00:00","links":{},"created":"2025-01-19T01:05:43.854710+00:00"}
