Configuring One Pair of Back-End 10GE Switches that Are Shared by Multiple Clusters

Configuring One Pair of Back-End 10GE Switches that Are Shared by Multiple Clusters

This section describes how to configure switches in a network where multiple clusters share a back-end switch.

Network Planning

Configuring one pair of back-end storage 10GE switches shared by multiple clusters is used as an example. You can go to the following links to configure management switches and front-end switches.
  • To configure CE5800 series switches, see chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Configuring a Management Network Switch in this document.

  • To configure CE6800 series switches, see chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Configuring Back-End Storage Network Switches in this document.

Table 4-3 shows switch planning examples. The planning values are only for your reference and are italic texts in commands. You can replace them based on site requirements.

Table 4-3  Network planning example

Cluster Name

Example

Cluster 1

Number of nodes: 10

VLAN: 2

Port: 1/0/1 to 1/0/10, 2/0/1 to 2/0/10

Cluster 2

Number of nodes: 10

VLAN: 3

Port: 1/0/11 to 1/0/20, 2/0/11 to 2/0/20

If the switch version varies, see the corresponding version of switches to complete switch configurations. For details about how to obtain switch configuration documents, see the related description in chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Switch Configuration Overview in this document.

Procedure

  1. Log in to a switch, query its version, and configure the stacking status for two switches.

    For details about how to log in to a switch, view its version, and configure stacking, see Check switch versions and Set switches CE6800-1 and CE6800-2 to the stack state in chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Configuring Back-End Storage Network Switches.

  2. Configure the PFC function for ports of the switch on the back-end storage network.

    #Create VLAN 2 and port group 2 and join the port of the back-end storage switch to which cluster 1 connects to port group 2.
    [~HUAWEI] vlan 2
    [*HUAWEI-vlan2] commit
    [~HUAWEI-vlan2] quit
    [~HUAWEI] port-group 2
    [*HUAWEI-port-group-2] group-member 10ge 1/0/1 to 10ge 1/0/10
    [*HUAWEI-port-group-2] group-member 10ge 2/0/1 to 10ge 2/0/10
    [*HUAWEI-port-group-2] commit
    #Configure hybrid for ports that are connected to the RoCE adapter, and specify the working mode of the PFC function. 
    [*HUAWEI-port-group-2] port link-type hybrid
    #ROCE port exits from VLAN 1. 
    [~HUAWEI-port-group-2] undo port hybrid untagged vlan 1
    [*HUAWEI-port-group-2] port hybrid tagged vlan 2
    [*HUAWEI-port-group-2] dcb pfc enable mode manual
    [*HUAWEI-port-group-2] commit
    [~HUAWEI-port-group-2] quit
    #Create VLAN 3 and port group 3 and join the port of the back-end storage switch to which cluster 2 connects to port group 3.
    [~HUAWEI] vlan 3
    [*HUAWEI-vlan2] commit
    [~HUAWEI-vlan2] quit
    [~HUAWEI] port-group 3
    [*HUAWEI-port-group-3] group-member 10ge 1/0/11 to 10ge 1/0/20
    [*HUAWEI-port-group-3] group-member 10ge 2/0/11 to 10ge 2/0/20
    [*HUAWEI-port-group-3] commit
     #Configure hybrid for ports that are connected to the RoCE adapter, and specify the working mode of the PFC function.
    [*HUAWEI-port-group-3] port link-type hybrid
    #ROCE port exits from VLAN 1.
    [~HUAWEI-port-group-3] undo port hybrid untagged vlan 1
    [*HUAWEI-port-group-3] port hybrid tagged vlan 3
    [*HUAWEI-port-group-3] dcb pfc enable mode manual
    [*HUAWEI-port-group-3] commit
    [~HUAWEI-port-group-3] quit
    #Set the priority.
    [~HUAWEI] dcb pfc
    [~HUAWEI-dcb-pfc] priority 0 to 5
    [*HUAWEI-dcb-pfc] commit
    [~HUAWEI-dcb-pfc] quit

  3. Configure an IP address for MEth0/0/0, configure SNMP, and check SNMP operations. For details, see Configure an IP address for port MEth0/0/0 and Configure SNMP in chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Configuring Back-End Storage Network Switches.
  4. Run the display current-configuration command and press Enter to check related configurations one by one.

Follow-up Procedure

The virtual network port ID of a storage node must be the same as the VLAN ID of the back-end storage switch. By default, the port ID is 2. When multiple clusters share one pair of back-end storage switches, multiple VLANs are required and the virtual network port IDs of storage nodes need to be changed accordingly. For details, see Modifying the Virtual Network Port ID on Each Storage Node.
