What is Multi-Protocol Access and how does ONTAP support NAS and SAN in the same cluster?

• A. ONTAP can only run either NAS or SAN in a cluster, not both.
• B. NAS and SAN share the same LIFs and volumes, so there's no isolation.
• C. ONTAP supports NAS protocols (NFS/SMB) and SAN protocols (iSCSI/FC); they utilize separate LIFs and volumes within the same cluster, enabling mixed workloads.
• D. Multi-Protocol Access requires separate clusters for NAS and SAN.

Answer: (C)

Multi-Protocol Access lets a single ONTAP cluster serve both NAS and SAN traffic at the same time. In ONTAP, NAS data (NFS/SMB) is accessed through file-style paths backed by volumes, while SAN data (iSCSI/FC) is exposed as LUNs and targets. The system achieves this by using separate network interfaces (LIFs) for each protocol path and separate storage objects (volumes for NAS and LUN-backed targets for SAN) within the same cluster. This separation provides clean, isolated routes for file and block traffic, allowing mixed workloads to run concurrently without stepping on each other. You don’t need separate clusters to support both NAS and SAN—the cluster can host both, with the NAS and SAN data kept on their respective LIFs and volumes.
