 note = {近年，汎用サーバと仮想化技術を用いて仮想マシンの動作状態ごとソフトウェア処理にて同期を行うことで高信頼システムを実現するソフトウェアFT技術が注目されている．本稿では，仮想化レイヤでサーバの動作状況に応じて同期周期を変動させながら待機系と同期を行うことにより，仮想マシン上の業務アプリケーションの実行性能への影響を抑えて，サーバ障害発生時に高速に待機系へ系切替可能な二重系動作環境同期機構について述べる．, Recently, the software fault tolerant technology (software FT) is paid to attention for achieving a dependable computing system. The software FT synchronizes each state of virtual machine between an active server and a standby server using virtualization technology. In this paper, we propose an dynamic redundancy control method that is possible to synchronize each state of virtual machine while suppressing effects on business applications by changing the synchronous cycle according to the server load. And it is possible to take-over at high speed to a standby server at active server machine breakdown.},
