Configuration Procedures - HP FlexFabric 5700 Series Configuration Manual

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 separate VSANs are as
follows:
One physical SAN is formed by the server, the IRF fabric, Switch C, and the disk device.
The other physical SAN is formed by the server, the IRF fabric, Switch D, and the disk device.
Because the server is connected to the same IRF fabric rather than two separate devices in the two
SANs, the two SANs must use different VSANs (for example, VSAN 100 and VSAN 200). The IRF
fabric must connect to the two VSANs.
• To transmit the Ethernet traffic of the LAN in VLAN 1001, configure the following interfaces to allow
VLAN 1001:
The Ethernet interfaces connecting the IRF fabric to the LAN.
The Ethernet interfaces connecting the IRF fabric to the server.
To transmit the storage traffic of the SANs in VSAN 100 and VSAN 200, perform the following
•
tasks:
Configure the interfaces connecting Switch A and Switch C to the SANs to allow VSAN 100.
Configure the interfaces connecting Switch B and Switch D to the SANs to allow VSAN 200.
To transmit the storage traffic of VSAN 100 within VLAN 4001, map VLAN 4001 to VSAN 100.
•
To transmit the storage traffic of VSAN 200 within VLAN 4002, map VLAN 4002 to VSAN 200.
•
To avoid physical loops in the LAN, enable STP on the Ethernet interfaces connecting the IRF fabric
•
to the LAN and the server. To prevent STP from blocking the interfaces that are responsible for
forwarding storage traffic on the IRF fabric, disable STP on the interfaces connecting the IRF fabric
to Switch C and Switch D.
The SANs are complex. HP recommends that you use the dynamic mode to build the fabric and use
•
FSPF for FC routing.
• To allow the server to access the resources in the disk device, configure the members in the default
zone to access each other.
To increase the bandwidth for the link between the IRF fabric and Switch C and implement link
•
backup and load sharing, configure Ethernet link aggregation group 1.
To increase the bandwidth for the link between the IRF fabric and Switch D and implement link
•
backup and load sharing, configure Ethernet link aggregation group 2.

Configuration procedures

This section describes only FC and FCoE configurations.
For information about configuring IRF, see the Virtual Technologies Configuration Guide.
An IRF port is a logical interface connecting IRF member devices. To use an IRF port, you must bind at
least one physical port to it. A link formed by IRF ports is called an IRF link.
Switch A and Switch B are configured to form an IRF fabric. You can configure the IRF fabric on any IRF
member device.
Configuring Switch A (after the IRF fabric is formed)
1. Enable the advanced mode:
# Configure the switch to operate in advanced mode. (Skip this step if the switch is operating in
advanced mode.)
