I just found a very cool webcast by Brent Ozar (blog|twitter) in which he shows how we can really dig-out the ugly truth around SAN storage and its performance. Probably you all know that the issue is not in the SAN, it is in your SQL Server…at least before this brilliant video (and script banks provided in the post).
The post and the video can be checked out here
So much said in just 45 minutes – this webcast is just amazing. I will definitely use it as a starting point whenever I have similar issues
