ESXi 6.5, vmfs 5

Dear all,

I recently installed ESXi 6.5 on local data store, I found that the file system is "VMFS 5". why not "VMFS 6"?

Kind regards

VMFS 5 and VMFS 6 can coexist. However, due to the changes done in VMFS 6 metadata structures to make it 4K aligned, you cannot inline/offline upgrade from VMFS5 to VMFS6.

You can leverage the new VMFS 6 capabilities by creating a new VMFS 6 datastore and provisioning new virtual machines to it or migrating the existing virtual machines from VMFS 5 datastore to VMFS 6 datastore.

It's indeed an interesting question, why VMware decided to use VMFS-5 for the datastore on the installation disk?

I don't think that they don't trust their own file system!? Smiley Wink

Let's wait and see whether someone from VMware responds to your question who can clarify if this was made by intention, or whether it's an installation bug.

yes, I know VMFS 5 and VMFS 6 can coexist

but, why VMware decided to use VMFS-5 for the data store on ESXi 6.5 installation disk?

Thanks.
