    5946 * [cloud:wiki:jazz/10-05-20 2010-05-20] 至中興大學演講，會後與另一場關於虛擬化的講者，麟瑞科技陳中欣先生聊到 NetApp 的 Deduplication 技術是 Block-level，也因此針對虛擬機器的 Disk 可以達到 deduplication 的目的。
    6047   * [[Image(http://trac.nchc.org.tw/cloud/raw-attachment/wiki/jazz/10-05-20/10-05-30_NetApp_Block-level-deduplication.png)]]

    6749 * [wiki:jazz/09-02-11#A-SISCOW 2009-02-11 : 關於 A-SIS & COW]
    … …  
    7557   * 目前有實作 Deduplication 概念的檔案系統並不多。或許可以進一步了解一下 A-SIS 是怎麼做 Block-level 的 Deduplication，這樣或許可以強化 DRBL AOE Windows 跟 Xen 虛擬化所需的硬碟空間。

    7761 * [wiki:jazz/09-09-23#FileSystem:lessfs:deduplication 2009-09-23] : 先前一直有在注意 virtualization 所帶來的資料重疊問題，!NetApp　在這方面就很厲害，可以從 File System 下手，把重複的檔案進行濃縮(deduplication)。今天剛好看到 Linux Magazine 的文章「[http://www.linux-mag.com/id/7535 Deduping Storage Depulication]」，裡面有提到目前許多商業解決方案，但自由軟體呢？目前似乎只有用 FUSE 寫的 [http://sourceforge.net/projects/lessfs/ lessfs]，它的官方網站　http://www.lessfs.com/ 目前並沒有太多資料，希望未來會有更多這類的檔案系統出現。我第一個想到的問題是在 loop device image 裡重複的檔案，該怎麼進行 deduplication 呢?? 同樣的 vmdk 這一些虛擬化的硬碟，有辦法作 deduplication 嘛??
