Fabric-Attached FC Connections
Huawei provides dual-controller and multi-controller storage systems, which connect to AIX hosts through FC multi-path connections using a switch in different ways.
Two-Controller Storage
The following uses Huawei OceanStor 5500 V3 as an example to explain how to connect an AIX host to a two-controller storage system through FC multi-path connections using a switch, as shown in Figure 3-3.
In this connection diagram, two controllers of the storage system and two ports of the AIX host are connected to the FC switch through optical fibers. On the FC switch, the ports connecting to the storage controllers and to the AIX host are grouped in a zone, ensuring connectivity between the host ports and the storage.

Zone division in this table is for reference only. Plan zones based on site requirements.
Multi-Controller Storage
The following uses Huawei OceanStor 18800 V3 (four-controller) as an example to explain how to connect an AIX host to a multi-controller storage system through FC multi-path connections using a switch, as shown in Figure 3-4.
In this connection diagram, four controllers of the storage system and two ports of the AIX host are connected to the FC switch through optical fibers. On the FC switch, the ports connecting to the storage controllers and to the AIX host are grouped in a zone, ensuring connectivity between the host ports and the storage.
