Requirements analysis
To meet the network requirements, perform the following tasks:
• To transmit the storage traffic over lossless Ethernet links in the SANs, HP 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 following interfaces to allow
VLAN 1001:
{ The Ethernet interfaces connecting Switch A and Switch B to the LAN.
{ The Ethernet interfaces connecting Switch A and Switch B to the server.
