Hey AakashJ
Thanks for your post! really helpful.
Excerpt: "So should you defrag your host’s VMFS volumes? The answer is no, for two reasons. First, it is not possible as there are no built-in or third party utilities available to execute the operation. The second reason is that the host VMFS data stores do not really fragment because of how virtual disks write to the VMFS volume. That’s not to say a VMFS volume cannot become fragmented at all. They do, but not to the extent that traditional OS disks become fragmented. This is because a standard OS can consist of many thousand of files that are fairly small in size, and a VMFS volume contains mostly very large virtual disk files."
So I guess the general rule is not to defrag your host’s VMFS volumes.
Kind Regards
Aaron
