Direct-Attached iSCSI Connections

Direct-Attached iSCSI Connections

Huawei provides dual-controller and multi-controller storage systems, which directly connect to SUSE hosts through iSCSI multi-path connections in different ways.

Two-Controller Storage

The following uses Huawei OceanStor 5500 V3 as an example to explain how to directly connect a SUSE host to a two-controller storage system through iSCSI multi-path connections, as shown in Figure 3-5.

Figure 3-5 Direct-attached iSCSI multi-path connections (two-controller storage)

NOTE:

In this connection diagram, each of the two controllers is connected to a port on the host network adapter with a network cable. The IP address plan is detailed in Table 3-6.
