Deploying a Converged Storage Network Using a Cisco FCoE Switch
10
Cabling
To connect the Fibre Channel and Ethernet cables:
1. Connect the Fibre Channel cables from the servers to the Cisco FCoE Nexus switch.
2. Connect the Fibre Channel cables from the storage to the Cisco FCoE Nexus switch.
3. Connect any necessary Ethernet cables for device management and iSCSI storage.
Configuring Fibre Channel Switches and Zoning
If you are connecting Fibre Channel devices, such as storage, through a Fibre Channel switch, then you
must connect the Fibre Channel switch to a Fibre Channel port on the FCoE switch. In addition, set
up a zoning configuration so that the servers can discover the disk LUNs you are mapping. For zoning
instructions, see the Fibre Channel switch documentation.
FCoE Switches
QLogic and Cisco have jointly developed the QLogic and Cisco FCoE Design Guide for implementing a
unified data center using Cisco Nexus 5000 Series FCoE switches and QLogic second-generation
converged network adapters. Refer to the design guide for detailed instructions on how to implement
an FCoE network and configure the Cisco Nexus FCoE switch and QLogic adapters (Cisco and
QLogic, 2010). The design guide also describes how to configure N_Port ID Virtualization (NPIV) to
resolve fabric expansion concerns related to domain IDs.
The QLogic and Cisco FCoE Design Guide does not describe the configuration of the PFC, ETS, and
DCB parameters, which will be required for the tests described in this document. For more details
about these parameters, see the Cisco Nexus 5000 Series Hardware Installation Guide.
Configuring DCB on a Nexus Switch
In this procedure, you may need to adjust some of the parameters, such as VLAN IDs, Ethernet
interfaces, and virtual Fibre Channel interfaces, to suit your environment. In this example, the Cisco
FCF uses NIC traffic on priority 2 and VLAN 2, and FCoE traffic on priority 3 and VLAN 1002.
To enable PFC, ETS, and DCB functions on a Cisco Nexus 5000 Series FCoE switch:
1. Log in to the switch and enter the configuration mode.
BR8K-21-cmsh# config t
2. Add the FCoE feature.
switch(config)# feature fcoe
3. Create and configure the VLAN interface for FCoE.
switch(config)# vlan 3
switch(config-vlan)# fcoe vsan 3
