The fact is that if the Operating System believes that the data is fragmented it will issue Split I/O requests to retrieve the data and this is costly and takes time. If the Operating System considers the data to be contiguous these costly Split I/O requests will be avoided, regardless of the SAN. Less I/O is ALWAYS better!<br /><br />Hopefully Adam can chime in here and add more detail.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2255932723148620062.post-6599073895050922662010-07-27T00:15:39.579+10:002010-07-27T00:15:39.579+10:00We use a SAN, so it is fragmented by design ;-)We use a SAN, so it is fragmented by design ;-)Anonymousnoreply@blogger.com
