When I am not blogging, I am typically working on SQL Server Optimization projects. Time and again, I only have access to SQL Server Management Studio that I can remotely connect to server but do not have access to Operating System, and it works just fine.
At one point in optimization project, I have to decide on index filegroup placement as well TempDB files (.ldf and .mdf) placement. It is commonly known that system gives enhanced performance when index and tempdb are on separate drives than where the main database is placed.
As I do not have access to OS I use the following Stored Procedure to figure out the number of fixed drives (hard drive) a system has along with free space on each of those drives. Based on this result, I decide my strategy of where to put my indexes and tempdb.
