  • Lookaheadlinkreader additional setting
    Posted: 09-20-2016, 1:46 AM

    Books online made it sound like this controlled the number of parallel read ahead on the remote DDB..  But it actually controls the number of source side maglib read aheads…

    http://documentation.commvault.com/additionalsetting/details?name=%22DataMoverLookAheadLinkReaderSlots%22&id=

    “Use this additional setting to improve the DASH copy and DASH full efficiency by performing more lookups on the destination deduplication databases (DDBs) for the deduplication block signatures.”

     

    Logged a case to see if there was recommended values and how it worked (160920-46).  I found out that this settings actually controls maglib lookups on the source MA, not DDB looksup on the remote MA (unless I'm missing a correlation).

    Can someone update the documentation to avoid confusion for others.

    Cheers,
