\n
\nRF 3 = 3 copies.
\n
\ni.e: RF2 for random-file-name-here.exe, which is 10G would take up 20G of storage
\n
\nRF3 for that same file would be 30G of storage
\n
\nThis assumes no data reduction, or use of erasure coding.
\n
\nErasure coding, Compression, Dedupe, and Zero suppression could make that 20G (or 30G) of storage much, much, much less","className":"post__content__best_answer"}">

    rf 2 = 2份

    rf 3 = 3份。

    即：RF2用于随机文件名 - 此处，这是10g的10g将占用20g存储

    RF3为同一文件为30G存储

    这假设没有数据减少或使用擦除编码。

    擦除编码，压缩，副品，零抑制可以使20g（或30克）的存储储存大多少，更少

    意思是说

    rf2：orignal数据实例+它的一个副本
    RF3：Orignal数据实例+ 2份

    对？
    谢谢

    \nRF2: orignal data instance + one copy of it

    是的。这些副本的碎片分散在整个群集中，但从未在与原件相同的节点上。
