You can configure FC and FC-NVMe SAN hosts to connect to HA pairs through one or more fabrics. You cannot directly attach FC or FC-NVMe SAN hosts to HA pairs without using a switch.
Cascade, partial mesh, full mesh, core-edge, and director fabrics are all industry-standard methods of connecting FC switches to a fabric, and all are supported. The use of heterogeneous FC switch fabrics is not supported, except in the case of embedded blade switches. Specific exceptions are listed on the Interoperability Matrix Tool.
You can configure FC and FC-NVMe SAN hosts with single fabric HA pairs or with multifabric HA pairs. The FC target port numbers (0a, 0c, 0d, 1a, 1b) in the illustrations are examples. The actual port numbers vary depending on the model of your storage node and whether you are using expansion adapters.
Single-fabric HA pairs
In single-fabric HA pair configurations, there is one fabric connecting both controllers in the HA pair to one or more hosts. Because the hosts and controllers are connected through a single switch, single-fabric HA pairs are not fully redundant.
All platforms that support FC configurations support single-fabric HA pair configurations.
Multifabric HA pairs
In multifabric HA pairs, there are two or more switches connecting HA pairs to one or more hosts. For simplicity, the following multifabric HA pair figure shows only two fabrics, but you can have two or more fabrics in any multifabric configuration:
