Typical Networking Scheme

Typical Networking Scheme

Figure 2-7 shows the 10GE networking scheme.

Figure 2-7  10GE network
NOTE:
  • This deployment solution applies to scenarios where the customer's switches are connected to the front-end service network. When CE6800 switches are connected to both the front-end service network and back-end storage network, VLANs must be assigned to isolate the front-end service network from the back-end storage network.
  • Ports on the back-end storage networks of different clusters must be isolated. When multiple clusters share one pair of CE6800 switches, VLANs need to be assigned to isolate back-end storage networks of different clusters.

Figure 2-8 shows how ports on a CE6800 switch are planned.

  • Downstream ports

    Each CE6800 switch uses 40 ports to connect to each node in sequential order.

    When both the front-end service network and back-end storage network are 10GE networks

    • The CE6800-1 switch connects to port A0-0 on each P/C/M node.
    • The CE6800-2 switch connects to port B3-0 on each P/C/M node.

    When the front-end service network is GE network and back-end storage network is 10GE network

    • The CE6800-1 switch connects to port A0-0
    • The CE6800-2 switch connects to port A0-1
  • Stack ports

    Stack ports on two CE6800 switches are connected mutually. The number of stack ports is subject to the number of nodes:

    • When the number of nodes is not larger than 16, use two ports for stacking switches.
    • When the number of nodes is larger than 16 but not larger than 24, use three ports for stacking switches.
    • When the number of nodes is larger than 24 but not larger than 40, use four ports for stacking switches.
  • Reserved ports

    Reserved ports are free ports. To prevent adverse impact on working ports, you are advised to run shutdown to shut down the reserved ports. For details on the shutdown command, refer to the related switch documentation.

  • ETH management network ports

    ETH management network ports are used to manage switches. The two ETH management network ports connect to an S5752/CE5800 switch.

When P/C/M nodes are deployed, the ports on an S5752 switch or a CE5800 switch are planned as shown in Figure 2-9 and Figure 2-10.

Figure 2-10  Example of planning ports on a CE5800 switch
  • IPMI downstream port

    An S5752/CE5800 switch uses 40 ports to connect to the IPMI ports of nodes in sequential order.

  • NIC0 downstream port

    When P/C/M nodes are deployed, the S5752/CE5800 switch uses ports 42 to 44 to connect to NIC0 ports on the first three nodes (nodes 01 to 03 in the basic cabinet) in the OceanStor 9000 cluster.

  • 10GE switch management ports

    10GE switch management ports connect to the ETH management network ports on the front of the two CE6800 switches.

  • (Optional) Upstream ports

    Upstream ports are used to connect to the user's management and maintenance network.

  • Reserved ports

    To prevent adverse impact on working ports, you are advised to run shutdown to shut down the reserved ports. For details on the shutdown command, refer to the related switch documentation.
