Direct-Attached iSCSI Connections
Huawei provides dual-controller and multi-controller storage systems, which directly connect to Solaris 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 Solaris host to a two-controller storage system through iSCSI multi-path connections, as shown in Figure 3-5.
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.

Multi-Controller Storage
The following uses Huawei OceanStor 18800 V3 (four-controller) as an example to explain how to directly connect a Solaris host to a multi-controller storage system through iSCSI multi-path connections, as shown in Figure 3-6.
In this connection diagram, each of the four controllers is connected to a port on host network adapters with a network cable. The IP address plan is detailed in Table 3-7.
