    Unanswered: What RAID to use really or does it not matter on a SAN

    Hi all,

    Is there any ground rules as to what RAID LEVEL to use for Oracle Databases, i.e. I mean as far as Oracle "Corporation" is concern?

    Am just looking for a piece of document or white paper where it says said "Oracle SAID use this !!!". I just get to deal with one dude who's been pestering me with what are Oracle and Oracle only recommendation.

    Any feedback will be very much appreciated.

    Thanks in advance.

    90% of users' problems can be resolved by punching them - the other 10% by switching off their PCs.

    Ask your storage vendor. They may have specific recommendations for using their hardware with Oracle.

    Oracle RDBMS does not know or care about under lying disk structure/architecture.
    It behaves the same regardless disk subsystem implementation.
    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.
    Good judgement comes from experience. Experience comes from bad judgement.

    Sure. But the storage architecture has a big impact on performance, resilience and availability of the database. Those are aspects of the system that most of us care about a lot

    I agree, but the Oracle s/w does not know or care about those externalities.
