For installation process following check list will be helpful
- Always fully document installs so that your SQL Server instances can easily be reproduced in an emergency.
- If possible, install and configure all of your SQL Server instances consistently, following an agreed-upon organization standard.
- Don’t install SQL Server services you don’t use, such as Microsoft Full- Text Search, Notification Services, or Analysis Services.
- For best performance of SQL Server running under Windows, turn off any operating system services that aren’t needed.
- For optimum SQL Server performance, you want to dedicate your physical servers to only running a single instance of SQL Server, no other applications.
- For best I/O performance, locate the database files (.mdf) and log files (.ldf) on separate arrays on your server to isolate potentially conflicting reads and writes.
- If tempdb will be used heavily, also put it on its own separate array.
- Do not install SQL Server on a domain controller.
- Be sure that SQL Server is installed on an NTFS partition.
- Don’t use NTFS data file encryption (EFS) and compression on SQL Server database and log files.
