Clustered Data ONTAP supports ALUA with which protocols?

Limiting ALUA support to FC only ignores FCoE and iSCSI, which are also SCSI-based transports that support ALUA in clustered ONTAP.

Excluding iSCSI is incorrect because iSCSI encapsulates SCSI commands over TCP/IP and fully supports ALUA in clustered ONTAP.

ALUA is a T10 SCSI standard that allows hosts to identify optimized versus non-optimized paths to LUNs, enabling intelligent multipath I/O. FC, FCoE, and iSCSI are all SCSI transport protocols and therefore support ALUA for active-active path management in clustered ONTAP. NFS is a NAS protocol and does not use SCSI semantics, so it has no concept of ALUA.

NFS is a NAS protocol and does not use SCSI, so it does not support ALUA; including NFS makes this choice incorrect.
