Introduction
Cisco Unified Computing System (UCS) is a unified computing solution that fuses access layer networking
and servers. This high−performance, next−generation server system provides the data center with a high
degree of workload agility and scalability.
The hardware and software components in the UCS support the unified fabric of Cisco, which allows multiple
types of data center traffic over a single physical Ethernet network. This Data Center Ethernet (DCE)
technology reduces the amount of cabling, management, and cost with the combination of the host bus
adapters (HBAs) and network interface cards (NICs) into a single adapter called the Converged Network
Adapter (CNA). This adapter can carry LAN and SAN traffic on the same cable.
Cisco UCS uses Fibre Channel over Ethernet (FCoE) protocol to carry Fibre Channel (FC) traffic inside
Ethernet frame. Cisco UCS also adheres to multiple 802.1 standards to provide the DCE underlying the FCoE
needs to effectively transport those frames. The fabric interconnect separates the LAN and SAN traffic from
the Ethernet frames and forwards them to the appropriate network ports. This gives the flexibility to deploy
this technology without the need of implementing the unified fabric solution across the entire data center
network.
Cisco UCS blade installed with Cisco UCS CNA M71KR E Emulex Converged Network Adapter or Cisco
UCS CNA M71KR Q QLogic Converged Network Adapter can handle both FC and IP simultaneously. The
converged network adapter presents an Ethernet interface and an Fibre Channel interface to the operating
system. The OS is completely unaware of the encapsulation taking place in the Ethernet segment. The only
requirement is for the OS to have the appropriate drivers to recognize the CNA hardware.
At the fabric interconnect, the server−facing Ethernet port receives the Ethernet and Fibre Channel traffic. The
fabric interconnect (which uses Ethertype to differentiate the frames) separates the two traffic types. Ethernet

    Fibre Channel frames are switched to their respective uplink interfaces. This document illustrates all the necessary steps to properly configure FCoE connectivity for a Cisco UCS blade using either of the CNA's. Prerequisites Requirements Cisco recommends that you: •...
  • Page 3: Background Information

    Refer to the Cisco Technical Tips Conventions for more information on document conventions. Background Information The Cisco UCS follows the FCoE protocol as defined by the ANSI T11 Standards Committee. The FC traffic encapsulated inside this Ethernet requires the same lossless network characteristics that are found in a fabric network.
  • Page 4 Before you begin, make sure that your upstream MDS switches are NPIV enabled, and assign the selected interface to the Cisco UCS with the appropriate VSAN number. The Cisco UCS must be up and operational by now and have basic connectivity established. 1. Verify that Cisco UCS Fabric Interconnect Supports FCoE Feature The Fabric Interconnect must be set in order to operate in FCoE mode.
  • Page 5 N10−E0080 JAB123800NM 2. Identify Fiber Channel components and Connectivity in Cisco UCS Before you configure the fabric interconnect to support VSAN, you need to make sure that your FC uplink expansion works and is visible from the fabric interconnect. Complete these steps: Log into UCS Manager GUI mode.
  • Page 6 3. Create VSAN to Support FCoE for FC Uplink The FC port defaults to VSAN 1 in Cisco UCS, but, if the upstream Fibre Channel switch is connected to a different VSAN #, the proper VSAN configuration is required on the FC ports of the Fabric Interconnect.
  • Page 7 Click the VSAN name you created in order to display your results. Now, repeat the same process for the uplink of Fabric B, except with VSAN 200 and VLAN 200 for Fabric B, you get this result:...
  • Page 8 4.1 Assign VSAN to FC Uplink Port in Fabric Interconnect Now assign the VSAN you just created to the FC Uplink port in your Fabric Interconnect that has a direct link to your SAN network. Complete these steps: In the Navigation pane, choose the Equipment tab. Choose Fabric Interconnect A >...
  • Page 9 In order to configure the second fabric, repeat steps 2 through 5. Cisco recommends that you use a different VSAN and a different FCoE VLAN to keep your fabrics separated. In this example, VSAN ID 200 and FCoE VLAN 200 were used.
  • Page 10 4.2 Assign VSAN to FC Uplink Port in Fabric Interconnect (Alternate Method) Choose the FC port linked to your SAN network and assign this port to the VSAN created in the previous step. These FC Uplinks must already be provisioned with respective VSAN IDs on the SAN network side (MDS switch).
  • Page 11 Click Save Changes. Repeat the same process for all other FC ports in Fabric A and Fabric B. 5. Create vHBA within Server Profiles Create two network adapters in a Service Profile to grant the Operating System access to the two SAN fabrics provisioned in previous steps.
  • Page 12 In the Create Service Profile pop−up window, fill in the Service Profile name. Click Next.
  • Page 13 In Storage section, add the vHBAs that you have just configured on Fabric Interconnect A and B. You can also give a name to these vHBA's. Make sure that you have selected the correct WWNN pool for these vHBAs.
  • Page 14 A vNIC is not assigned in this Service Profile for FCoE. Choose No vNICs and click Next. Choose the server boot order policy to use and click Next. If you do not want to choose any policy, then click Next.
  • Page 15 In the Server Assignment window, choose the server pool to use and click Next. If you do not want to choose a server pool now, click Next. Choose the IPMI profile and the SoL Configuration profile that you wnat to apply to this policy and click Finish.
  • Page 16 The results are successful. The created vHBAs are visible in the vHBA tab of your created profile.
