デバイス間でデータを移動させる処理の一例である．現在のコンピュータシステムでは，ネットワークインタフェースカード (NIC) や Solid-State Drive (SSD) をはじめとした I/O デバイス間でデータを移動する場合，データを一度ホストサーバのメインメモリに送る必要がある．このため，ホストサーバと I/O デバイスがネットワークで接続されたコンピュータシステムでは，ホストサーバのネットワークリンクが I/O デバイス間のデータ移動のボトルネックとなっていた．本稿では，I/O デバイス間のデータ移動をホストサーバを経由せず直接行うことで，データ移動帯域のボトルネックを解消し，広帯域にデータ移動を行う手法を提案する．2 つの PCI Express (PCIe) SSD を用いて評価を行った結果，データ移動帯域が従来手法より 86% 向上し，SSD の最大性能でデータ移動を行うことが出来た．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Data transfer between storage devices for data reallocation in a storage system and backing up data from a client to a network-attached storage are examples of data processing that transfers data between I/O devices without modifying data. In current systems, transferred data between I/O devices must be sent once to the main memory of the server hosting the I/O devices. However, in a system which interconnects a host server and I/O devices using a network method, the network bandwidth of the server becomes a bottleneck for data transfer. This paper proposes a method to transfer data directly between I/O devices. Evaluation using two PCI Express (PCIe) solid-state drives (SSDs) showed the proposed method increased the bandwidth of the data transfer by 86% and to the maximum throughput of the SSD.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-02-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"2012-OS-120"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":80717,"updated":"2025-01-21T19:42:09.042791+00:00","links":{},"created":"2025-01-18T23:35:06.140330+00:00"}
