Configuring Storage Connections

This chapter contains the following sections:

VSANs

In Cisco UCS, a VSAN, also known as a named VSAN, creates a connection to a specific external SAN. The VSAN isolates traffic to that external SAN, including broadcast traffic. The traffic on one VSAN knows that the traffic on another VSAN exists but cannot read or access that traffic.

The name that you assign to a VSAN ID adds a layer of abstraction that allows you to globally update all servers associated with service profiles that use the VSAN. You do not need to reconfigure the servers individually to maintain communication with the external SAN. You can create more than one named VSAN with the same VSAN ID.

For more information about VSANs in Cisco UCS, including guidelines and recommendations, see the Cisco UCS Manager configuration guides.

Named VSANs in Cluster Configurations

In a cluster configuration, a VSAN can be configured to be accessible only to the Fibre Channel uplink ports on one fabric interconnect or to the Fibre Channel uplink ports on both fabric interconnects.

Named VSANs and the FCoE VLAN ID

Configure each VSAN with an FCoE VLAN ID. This property determines which VLAN is used for transporting the VSAN and its Fibre Channel packets.

For FIP-capable, converged network adapters, such as the Cisco UCS CNA M72KR-Q and the Cisco UCS CNA M72KR-E, the VSAN must be configured with a VLAN that is not the native VLAN for the FCoE VLAN ID. This configuration ensures that FCoE traffic can pass through these adapters.

In the following sample configuration, a service profile with a vNIC and vHBA mapped to fabric A is associated with a server that has FIP capable, converged network adapters:

  • The vNIC is configured to use VLAN 10.

  • VLAN 10 is also designated as the native VLAN for the vNIC.

  • The vHBA is configured to use VSAN 2.

  • Therefore, VSAN 2 cannot be configured with VLAN 10 as the FCoE VLAN ID. VSAN 2 can be mapped to any other VLAN configured on fabric A.

Creating a VSAN


Note

Fibre Channel over Ethernet (FCoE) VLANs in the SAN cloud and VLANs in the LAN cloud must have different IDs. Using the same ID for an FCoE VLAN in a VSAN and a VLAN results in a critical fault and traffic disruption for all vNICs and uplink ports using that FCoE VLAN. Ethernet traffic is dropped on any VLAN that has an ID that overlaps with an FCoE VLAN ID.

Procedure
    Step 1   Choose Physical > Compute.
    Step 2   On Compute page, choose the pod that includes the Cisco UCS Manager account.
    Step 3   Click VSANs.
    Step 4   Click Add.
    Step 5   On the Add VSAN screen, complete the following fields:
    Name Description

    VSAN Name field

    A unique name for the VSAN.

    VSAN ID field

    The unique identifier assigned to the network.

    Type drop-down list

    Choose the type of VSAN. This can be one of the following:

    • SAN Cloud

    • Storage Cloud

    If you are creating a VSAN for Fibre Channel zoning, we recommend that you choose Storage Cloud.

    Fabric ID drop-down list

    Choose how to configure the VSAN. This can be one of the following:

    • Common/Global—The VSAN maps to the same VSAN ID in all available fabrics.

    • Fabric A—The VSAN maps to a VSAN ID that exists only in fabric A.

    • Fabric B—The VSAN maps to a VSAN ID that exists only in fabric B.

    FCoE VLAN field

    The unique identifier assigned to the VLAN used for Fibre Channel connections.

    For FCoE Initialization Protocol (FIP)-capable, converged network adapters, such as the Cisco UCS CNA M72KR-Q and the Cisco UCS CNA M72KR-E, the named VSAN must be configured with a named VLAN that is not the native VLAN for the FCoE VLAN ID. This configuration ensures that FCoE traffic can pass through these adapters.

    Step 6   Click Submit.
    What to Do Next

    If you plan to use this VSAN for Fibre Channel zoning, see Configuring a VSAN for Fibre Channel Zoning.

                    Interrupt Mode drop-down list

                    Choose the method used to send interrupts to the operating system from the driver. This can be one of the following:

                    • MSI-X—Message Signaled Interrupts (MSI) with the optional extension. We recommend that you select this option if the operating system on the server supports it.

                    • MSI—MSI only.

                    • INTx—PCI INTx interrupts.

                    Note   

                    This parameter applies only to a server with a VIC adapter or a network adapter running an operating system other than Windows. The Windows operating system ignores this parameter.

                    Step 10   Click Submit.

                    SAN Connectivity Policy

                    SAN connectivity policies determine the connections and the network communication resources between the server and the LAN on the network. These policies use pools to assign WWNs and WWPNs to servers and to identify the vHBAs that the servers use to communicate with the network.


                    Note

                    We do not recommend that you use static IDs in connectivity policies, because these policies are included in service profiles and service profile templates and can be used to configure multiple servers.

                    Creating a SAN Connectivity Policy

                    Procedure
                      Step 1   Choose Physical > Compute.

                      3. To create a new vHBA without a template, do not check the Use vHBA Template check box and complete the fields that are displayed.

                        For more information about these fields, see Creating a vHBA.

                      4. Click Submit.

                      Repeat this step if you want to add additional vHBAs to the policy.

                      Step 10   After you have created all vHBAs required for the policy, click Submit.

                      Storage Policy

                      The storage policy is a Cisco UCS Director policy that configures the connections between a server and SAN storage, including the World Wide Node Name (WWNN) assigned to the server and the virtual host bus adapters (vHBAs) used by the server. Depending upon the configuration you choose, this policy can be used to configure two or more vHBAs for the server. You can choose to create the vHBAs in this policy or use a SAN connectivity policy to determine the vHBA configuration.

                      You must include this policy in a service profile and that service profile must be associated with a server for it to take effect.

                      Creating a Storage Policy

                      Procedure
                        Step 1   Choose Policies > Physical Infrastructure Policies > UCS Manager.

                        Fibre Channel Zoning

                        Support for Fibre Channel Zoning in Cisco UCS

                        Cisco UCS supports switch-based Fibre Channel zoning and Cisco UCS local Fibre Channel zoning (also known as Cisco UCS Manager-based Fibre Channel zoning). You cannot configure a combination of zoning types in the same Cisco UCS domain. You can configure a Cisco UCS domain with one of the following types of zoning:

                        • No zoning

                        • Cisco UCS local Fibre Channel zoning—This configuration combines direct attach storage with local zoning. Fibre Channel or FCoE storage is directly connected to the fabric interconnects and zoning is configured in Cisco UCS, using local zoning. Any existing Fibre Channel or FCoE uplink connections must be disabled. Cisco UCS does not currently support active Fibre Channel or FCoE uplink connections that coexist with the utilization of the Cisco UCS local zoning feature.

                        • Switch-based Fibre Channel zoning—This configuration combines direct attach storage with uplink zoning. The Fibre Channel or FCoE storage is directly connected to the fabric interconnects and zoning is performed externally to the Cisco UCS domain through a Cisco MDS or Nexus 5000 Series switch. This configuration does not support local zoning in the Cisco UCS domain.


                        Note

                        Zoning is configured on a per-VSAN basis. You cannot enable zoning at the fabric level.

                        For more information about Fibre Channel zoning, including guidelines for implementing it, see the Cisco UCS Manager configuration guides.

                        Storage Connection Policy

                        The storage connection policy contains a collection of target storage ports on storage arrays that you use to configure Cisco UCS local Fibre Channel zoning. You can create this policy underneath an organization or an initiator group. This policy is known as a Fibre Channel storage connection policy in Cisco UCS Manager.

                        You add vHBA initiator groups to a storage connection policy through the Fibre Channel target endpoints.

                        The storage arrays in these zones must be directly connected to the fabric interconnects. The target storage ports on these arrays that you include in the storage connection policy can be either Fibre Channel storage ports or FCoE storage ports. You use the WWN of a port to add it to the policy and to identify the port for the Fibre Channel zone.


                        Note

                        Cisco UCS does not create Fibre Channel storage by default.

                        Configuring Fibre Channel Zoning in Cisco UCS


                        Note

                        This procedure provides a high-level overview of the steps required to configure a Cisco UCS domain for Cisco UCS local Fibre Channel zoning. Ensure that you complete all of the following steps.

                        Procedure
                           Command or ActionPurpose
                          Step 1If you have not already done so, disconnect the fabric interconnects in the Cisco UCS domain from any external Fibre Channel switches, such as an MDS.  

                          If the Cisco UCS domain still includes zones that were managed by the external Fibre Channel switch, enter the clear-unmanaged-fc-zone-all command on every affected VSAN to remove those zones.

                          You must perform this step in the Cisco UCS Manager CLI.

                           
                          Step 2Configure the Fibre Channel switching mode for both fabric interconnects in Fibre Channel switch mode.  

                          You cannot configure Fibre Channel zoning in end-host mode.

                          See Changing Fibre Channel Switching Mode.

                           
                          Step 3Configure the Fibre Channel and FCoE storage ports that you require to carry traffic for the Fibre Channel zones.  

                          See Configuring Fabric Interconnects and Ports.

                           
                          Step 4Create one or more VSANs and enable Fibre Channel zoning on all VSANs that you require to carry traffic for the Fibre Channel zones.  

                          For a cluster configuration, we recommend that you create the VSANs that you intend to include in a storage zone and use the common or global configuration to ensure that they are accessible to both fabric interconnects.

                          See Creating a VSAN and Configuring a VSAN for Fibre Channel Zoning.

                           
                          Step 5Create a LAN connectivity policy.  

                          See Creating a LAN Connectivity Policy.

                           
                          Step 6Create a network policy and add the LAN connectivity policy to it.  

                          See Creating a Network Policy.

                           
                          Step 7Create a SAN connectivity policy.  

                          See Creating a SAN Connectivity Policy.

                           
                          Step 8Create a storage policy and add the SAN connectivity policy to it.  

                          See Creating a Storage Policy.

                           
                          Step 9Create one or more storage connection policies and include one or more Fibre Channel target endpoints to serve as vHBA initiator groups.  

                          See Creating a Storage Connection Policy.

                           
                          Step 10Create a service profile and add the network policy and storage policy to it.  

                          See Creating a Service Profile.

                           
                          Step 11Associate the service profile with a server.    
                          Step 12View and generate reports for the Fibre Channel zones through a service profile and/or organization.   (Optional)

                          See Viewing Fibre Channel Zones.

                           
                          Step 13If you modify the LAN and/or SAN connectivity policies, which causes the server to reboot, request inventory collection for the service profile and the server.   (Optional)

                          See Requesting Inventory Collection for a Service Profile and Requesting Inventory Collection for a Server.
