Overview

Overview

Networking

OceanStor 9000 has the following networks:

  • Front-end service network

    This network interconnects OceanStor 9000 with the service network of a customer for clients to access services, short for the front-end network.

    NOTE:
    To prevent the service network of the customer from being adversely affected by the interconnection, confirm existing configurations on the service network of the customer in advance.
  • Back-end storage network

    This network is used by all internal nodes of OceanStor 9000 for internal communication, short for the back-end network

  • Management network

    This network interconnects OceanStor 9000 with the management network of a customer. Then, the maintenance terminal of the customer can access OceanStor 9000

Figure 1-1 shows the typical networks of OceanStor 9000.

Planning the Number of Cluster Nodes

In video surveillance scenarios, a cluster consists of one or more than two nodes. In other scenarios, a cluster consists of at least three nodes.

NOTE:
When C72 nodes are deployed, a cluster consists of at least two nodes in all scenarios.

Planning Switches

OceanStor 9000 nodes use different switches in different network solutions. The switches used on the typical networks are listed as follows:
  • CE6810-24S2Q-LI

    10GE switch, CE6800 for short. Used as the back-end switch, providing 24 10GE SFP+ optical ports and 2 40GE QSFP+ optical ports.

  • CE6810-48S4Q-EI

    10GE switch, CE6800 for short. Used as the back-end switch, providing 48 10GE SFP+ optical ports and 4 40GE QSFP+ optical ports.

  • CE6851-48S6Q-HI

    10GE switch, CE6800 for short. Used as the back-end switch, providing 48 10GE SFP+ optical ports and 6 40GE QSFP+ optical ports.

  • CE6855-48S6Q-HI

    10GE switch, CE6800 for short. Used as the back-end switch, providing 48 10GE SFP+ optical ports and 6 40GE QSFP+ optical ports.

  • SX6018

    IB switch, providing 18 56Gb ports and supporting a 16-node network. When an IB network is used, use this switch as the back-end switch.

  • SX6036

    IB switch, providing 36 56Gb ports and supporting a 34-node network. When an IB network is used, use this switch as the back-end switch.

  • S5700-52C-SI/S5352C-SI

    GE switch, S5752/S5352 for short.

  • CE5855-48T4S2Q-EI

    GE switch, CE5800 for short. Used as the management switch, providing 48 10/100/1000BASE-T Ethernet electrical ports, 4 10GE SFP+ optical ports, and 2 40GE QSFP+ optical ports.

NOTE:

S5752 and S5352 switches are used in the same way. S5752 switches will be used as examples to introduce the OceanStor 9000 network.

At the data link layer, if the number of network ports on the storage nodes connected to the CE6800 switches exceeds 100, run the arp anti-attack rate-limit 500 command on the switches to change the upper limit of processing the ARP packets to prevent the switches from discarding ARP packets.
