Note: On ESXi 5.x hosts using VMFS5 upgraded from VMFS3, the upgraded volumes inherit the VMFS3 block size.
The default block size for new volumes is 1MB. The maximum file size, regardless of block size, is 2TB - 512Bytes.
While it does retain the 1MB size, on VMFS 5, that is the default and a VM can be up to 2TB.
