SQL Server & SharePoint Recommendations:
* tempdb data and t-log files
* Db transaction log files
* Search db data files
* Content db data files
-> Place tempdb, Content db and t-logs on separate LUNs/drives if possible
-> Use multiple database files for Content and Search databases.
-> By following the above we can get significant performance changes.
-> Place SharePoint Search crawl and query processing tables on separate spindles.
-> Content databases are still limited to 100GB as a best practice.
-> They do have customers running close to 1TB of data.
-> Pre-allocate data file to cover anticipated size of Content db
-> Rely on SQL 'Autogrow' only as a catastrophic insurance policy
-> Set SQL 'Autogrow' to fixed value appropriate size of db
-> Configure tempdb to be at least 10% of total Content db size, or the size of the largest table - whichever is greater
* Monitor SQL Server performance regularly
* Check integrity of the db routinely
* DBCC CHECKDB
