Fabric-Attached FC Connections

Fabric-Attached FC Connections

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

Figure 3-3 Fabric-attached FC multi-path connections (dual-controller storage)

NOTE:

In this connection diagram, two controllers of the storage system and two ports of the SUSE host are connected to the FC switch through optical fibers. On the FC switch, the ports connecting to the storage controllers and to the SUSE host are grouped in a zone, ensuring connectivity between the host ports and the storage.

Table 3-4 Zone division on the FC switch (two-controller storage)

Zone Name

Zone Members

Zone Description

Zone001

Ports 1 and 2

Connects Port P0 on the SUSE host to Controller A on the storage system.

Zone002

Ports 3 and 4

Connects Port P1 on the SUSE host to Controller B on the storage system.

Zone003

Ports 1 and 4

Connects Port P0 on the SUSE host to Controller B on the storage system.

Zone004

Ports 3 and 2

Connects Port P1 on the SUSE host to Controller A on the storage system.

NOTE:

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 a SUSE host to a multi-controller storage system through FC multi-path connections using a switch, as shown in Figure 3-4.

NOTE:

In this connection diagram, four controllers of the storage system and two ports of the SUSE host are connected to the FC switch through optical fibers. On the FC switch, the ports connecting to the storage controllers and to the SUSE host are grouped in a zone, ensuring connectivity between the host ports and the storage.
