What is the block size of 1048576 in VMware?
Log in to the ESX console. Where 1048576 is equivalent to a 1 MB block size on a VMFS datastore. Note: vSphere 5.0 and later releases have a block size of 1 MB only. There is no noticeable I/O performance difference when using a larger block size on thick provisioned virtual disks (VMDK).
What is the size of a VMFS sub-block?
VMFS-3 uses sub-blocks for directories and small files with a size smaller than 64 KB. When the VMFS uses 1 sub-block of 64 KB, we switch to file blocks. The size of the file block depends on the block size you selected when the datastore was created.
