Overview

Overview

Networking Planes

The FusionStorage storage system provides the following networking planes:
  • Service plane

    This network plane interconnects FusionStorage with the service network of a customer for clients to access services.

  • Management plane

    This network plane interconnects FusionStorage with the management network of a customer for cluster management.

  • Storage plane

    The network plane is used by each node of FusionStorage for data communications between storage nodes and between computing nodes and storage nodes.

  • BMC network

    This network is used to remotely manage hardware by connecting to the Mgmt port of a FusionStorage node.

Application Scenario

10GE networking applies to the virtualization of blade servers or rack servers.

RoCE networking is applicable to the scenarios with low latency, low CPU load, and large bandwidth, such as clusters, computing, and big data storage.

InfiniBand networking is applicable to scenarios where a large amount of data is required, such as critical enterprise databases, data warehouses, critical enterprise resource planning (ERP), and customer relationship management (CRM).

Switches used in the networking are as follows:
  • CE6851-48S6Q-HI

    10GE switch, CE6800 for short. Serves as a storage switch and provides forty-eight 10GE SFP+ Ethernet optical ports and six 40GE QSFP+ Ethernet optical ports.

  • CE6855-48S6Q-HI

    10GE switch, CE6800 for short. Serves as a storage switch and provides forty-eight 10GE SFP+ Ethernet optical ports and six 40GE QSFP+ Ethernet optical ports.

  • CE6860-48S8CQ-EI

    10GE/25GE switch, CE6800 for short. Serves as a storage switch and provides forty-eight 10GE/25GE SFP28 Ethernet optical ports and eight 40GE/100GE QSFP28 Ethernet optical ports.

  • SX6018/SX6036

    56Gb IB switch. Serves as a storage switch. SX6018 provides eighteen 56Gb QSFP+ Ethernet optical ports and SX6036 provides thirty-six 56Gb QSFP+ Ethernet optical ports.

  • CE5855-48T4S2Q-EI

    GE switch, CE5800 for short. Serves as a BMC/management switch and provides forty-eight 100/1000BASE-T Ethernet electrical ports, four 10GE SFP+ Ethernet optical ports, and two 40GE QSFP+ Ethernet optical ports.

NOTE:

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 in the system view on the switches to change the upper limit of processing the ARP packets to prevent the switches from discarding ARP packets.
