Several protocols allow you to access data on the storage system.
Files written using one protocol are accessible to clients of any protocol, provided that system licenses and permissions allow it. For example, an NFS client can access a file created by a CIFS client, and a CIFS client can access a file created by an NFS client. Blocks written using one protocol can also be accessed by clients using the other protocol.
For information about NAS file access protocols, see the Data ONTAP File Access and Protocols Management Guide.
For information about SAN block access protocols, see the Data ONTAP Block Access Management Guide for iSCSI and FCP.
