Open Stack

Is there any plan in openstack for managing the shared block storage using only the data plane? Just like the VMFS for VMware and "SPM+LVM2" for Ovirt.

If the management plane of the SAN was unreachable, how about openstack for this?

The standard protocols (iSCSI, NFS, CIFS, etc.) generally only address
the user plane and partially the control plane. Standardizing the
management plane is left to the user or vendors. One of the roles
of OpenStack is to fill that gap.

Cinder addresses block storage.
The proposed Manila project would deal with NAS.
