ONTAP offers the same NFS, SMB/CIFS, and iSCSI protocols in the Cloud that you are using today.
File sharing with NFS and SMB/CIFS and the Cloud
The NFS and SMB/CIFS protocols are used to make shares and files available to client applications over a network. Cloud Volumes ONTAP enables you to provide files from a public cloud using either or both of these protocols.
iSCSI and the Cloud
The iSCSI protocol provides block-level storage to clients such as databases and other applications that want block storage instead of files. ONTAP provides the iSCSI protocol in the Cloud.
