In reviewing the posts on this forum for OS disk defragmentation, I'm confused.
Is it truly necessary to defrag the OS disk on a SQL server?
Our data is located on a SAN. The drive the data files is located on is fragmented to 51%.
Would you recommend we run the Windows defrag tool on this drive?
What is the pro/con to doing this? I'm assuming this is something we should do after hours due to performance.
Any guidance is most appreciated.
