Deduplication

  • What’s the method and scope of deduplication?

    There isn’t any explanation covering this feature, other than there is an impact on performance.

    Is it limited to a volume, VSM, or pool?

    Once you enable De duplicaion on Pool Level. All the Volumes under this will be capable of using this feature.

    Hi Martin,

    I really wanted to about the deduplication feature. There is no documentation, other than mention of a deduplication feature.

    Is it simply mapping files with the same content? Is it using hash functions to compare these files? What’s the method, should I be concerned about hash collisions?

    If it’s enabled on the pool, is deduplication automatic for every volume? What is the level of control?

    Sincerely,
    Brian LaVallee
