ESX Setup: Defining block sizes

Attention!

When configuring ESX/creating new VMFS volumes, some people tend to mess around with block size. This will interfere with the maximum file size you can create on those volumes.

For example, if you then need a bigger VMDK file, you will need to delete and recreate your VMFS partition with a larger block size!

Block Size = Maximum file size

1024 = 256Gb
2048 = 500Gb
4096 = 1000Gb
