Requirements analysis
To transmit the storage traffic over lossless Ethernet links in the SANs, H3C recommends that you perform
the following tasks:
• Configure DCBX, PFC in auto mode, and ETS on the Ethernet interfaces connecting the switches to
the server.
• Configure DCBX and PFC in auto mode on the Ethernet interfaces connecting the switches to the
disk device.
• Enable PFC by force on the Ethernet interfaces connecting switches.
To implement link backup between the server and the disk device, use two separate SANs to provide
connections between the server and the disk device. The two SANs can use the same VSAN. The two
separate VSANs are as follows:
• One physical SAN is formed by the server, Switch A, Switch C, and the disk device.
• The other physical SAN is formed by the server, Switch B, Switch D, and the disk device.
To transmit the Ethernet traffic of the LAN in VLAN 1001, configure the Ethernet interfaces connecting
Switch A and Switch B to the LAN and the server to allow VLAN 1001.
To transmit the storage traffic of the SANs in VSAN 100, configure the interfaces connecting the four FCF
switches to the SANs to allow VSAN 100.
