dc.description.abstract | 一般系統如果遇到斷電或是系統崩潰, 主記憶體上資料都將遺失。對於資料正確性要求高的環境, 會使用UPS(uninterruptible power supply) 保護整個系統, 使其能夠安全關機。而UPS 為了維持整個系統運作, 需要不少電量, 尤其大型伺服器可能使用了上百台的主機跟儲存裝置, 若要以UPS 保護系統則需要非常昂貴的成本。我們提出了一個方法使其能夠保護資料,且不需要太大的成本。我們用非揮發性記憶體(或是電池備援記憶體) 作為主記憶體, 使其在斷電後可以保留住資料, 維持記憶體電力直到電源恢復。復電後再依照我們所設計之流程, 集合檔案系統日誌功能將資料寫回磁碟, 減少資料損失。 | zh_TW |
dc.description.abstract | In general system, all data in main memory are lost when occur power interruption.Use UPS(uninterruptible power supply) to protect entire system is a approach for reduce data losing. But it is also expensive for large system which need a high capacity UPS.We propose a new apporach:use standby power to protect main memory instead protect entire system. Maintain in-memory data until power restore and then write data to disk.We integrate characteristic of non-volatile memory and file-system journaling for reduce data losing in on power interrupt. | en_US |
