Fabric-Attached iSCSI Connections
Huawei provides dual-controller and multi-controller storage systems, which connect to Windows hosts through Ethernet switches in different ways.
Two-Controller Storage
The following uses Huawei OceanStor 5500 V3 as an example to explain how to connect a Windows host to a two-controller storage system through iSCSI multi-path connections using an Ethernet switch, as shown in Figure 3-7.
NOTE: In this connection diagram, two controllers of the storage system and two ports of the Windows host network adapter are connected to the Ethernet switch through network cables. IP addresses of the ports on the storage and host are in the same subnet, ensuring connectivity between the host ports and the storage.
Port Name |
Port Description |
IP Address |
Subnet Mask |
|---|---|---|---|
Host.P0 |
Connects the Windows host to Controller A on the storage system. |
192.168.5.5 |
255.255.255.0 |
Host.P1 |
Connects the Windows host to Controller B on the storage system. |
192.168.6.5 |
255.255.255.0 |
Storage.A.P0 |
Connects Controller A on the storage system to the Windows host. |
192.168.5.6 |
255.255.255.0 |
Storage.B.P0 |
Connects Controller B on the storage system to the Windows host. |
192.168.6.6 |
255.255.255.0 |

Multi-Controller Storage
The following uses Huawei OceanStor 18800 V3 (four-controller) as an example to explain how to connect a Windows host to a multi-controller storage system through iSCSI multi-path connections using an Ethernet switch, as shown in Figure 3-8.
NOTE: In this connection diagram, four controllers of the storage system and four ports of the Windows host network adapters are connected to the Ethernet switch through network cables. IP addresses of the ports on the storage and host are in the same subnet, ensuring connectivity between the host ports and the storage.
