Required 9’s

    Soru

  • I keep seeing reference to "Required 9's" in the documentation for SQL Server 2012 HA, but I can't find the actual list of what these nines are.
    Could someone please be so kind as to give me the list of Required 9's or explain the term?

  • Hi,

    Required 9s means its a term to represent sql server up time with SQL Server 2012 .99.99999 is the server uptime .

    Every one wants server uptime 99.9999 .we can achive this figure by useing SQL Server 2012 HA(Always On) .


    Thanks&Regards Siva G

  • Thank you David,

    The Percentage calculation table of how the nines work explains it really well. I searched on Wikipedia for "required 9's", but I should have tried High Availability as well.
