Fabric-Attached iSCSI Connections

Fabric-Attached iSCSI Connections

Huawei provides dual-controller and multi-controller storage systems, which connect to SUSE 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 SUSE host to a two-controller storage system through iSCSI multi-path connections using an Ethernet switch, as shown in Figure 3-7.

Figure 3-7 Fabric-attached iSCSI multi-path connections (two-controller storage)

NOTE:

In this connection diagram, two controllers of the storage system and two ports of the SUSE 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.

Multi-Controller Storage

The following uses Huawei OceanStor 18800 V3 (four-controller) as an example to explain how to connect a SUSE host to a multi-controller storage system through iSCSI multi-path connections using an Ethernet switch, as shown in Figure 3-8.

Figure 3-8 Fabric-attached iSCSI multi-path connections (four-controller storage)

NOTE:

In this connection diagram, four controllers of the storage system and four ports of the SUSE 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.
