I have a lot of servers from Exchange, Hyper-V, IIS, etc.running on server 2003 & 2008 and am trying to determine if it is really worth defragging them. SCOM reports high fragmentation levels on some from 40% to 95%. In my researching, I see people say it's not worth it and the ones that say it is are primarily from companies selling defrag solutions. My hesitation to defrag goes way back to the 90's when defragging had a possibility to damage, especially if shut down during a defrag.
Can I get a few opinions out there?
