There is an error "failed to create configuration database" while installing sharepoint 2016 with an addition message "sql server instance does not have the required "max degree of parallelism" setting of 1".
What is Max Degree of Parallelism ?
When an instance of SQL Server runs on a computer that has more than one microprocessor or CPU, it detects the best degree of parallelism, that is, the number of processors employed to run a single statement, for each parallel plan execution. You can use the max degree of parallelism option to limit the number of processors to use in parallel plan execution. SQL Server considers parallel execution plans for queries, index data definition language (DDL) operations, and static and keyset-driven cursor population.
