Yes they can however this depends on how you formated the LUN.

VMFS with a 1MB block size can have virtual disk files up to 256GB

VMFS with a 2MB block size can have virtual disk files up to 512GB

VMFS with a 4MB block size can have virtual disk files up to 1024GB

VMFS with a 8MB block size can have virtual disk files up to 2048GB

Yes. It can be as big as 2 TB. However, Your operating system should support such a big filesystem, Which most of the moderan OS should do.

Check this for configuration max with VMware.

Let me know if this helps.

You only get the option when creating a datastore, you can't change it later without reformatting it (and losing the data). You could storage vmotion all the VMs to a temp datastore and then reformat it and move them back though
