Considerations for FC-NVMe configurations

Beginning with ONTAP 9.4, the non-volatile memory express (NVMe) protocol is available for SAN environments. FC-NVMe allows you to run NVMe over an existing FC network with an AFF system. FC-NVMe uses the same physical setup and zoning practice as traditional FC networks but allows for greater bandwidth, increased IOPs and reduced latency than FC-SCSI.

The following applies only to nodes running ONTAP 9.4:

The following ONTAP features are not supported by NVMe configurations:
