Deployment Solution Description

Deployment Solution Description

Hardware Configuration

Figure 4-8 shows the typical cabinet configuration for Capacity node. For example, in a high-performance storage project, three Capacity node are used. The front-end and back-end networks share a pair of CE6800 switches, and a CE5800 switch is used as the network management switch for the entire cluster.

Figure 4-8  Capacity node cabinet configuration

Node Ports

Figure 4-9 shows the ports on a node. All nodes have the same ports.

Figure 4-9  Network ports on nodes

Table 4-6 describes the use of network ports when both the front-end and back-end networks employ 10GE networking.

Table 4-6  Node port usage

Port Name

Port Type

Network

Description

A0-0 and B3-0

10GE optical port

Back-end storage network

Connect to the CE6800 switches. A back-end storage network IP address is configured for each of the two ports.

A0-1 and B3-1

10GE optical port

Front-end service network

Connect to the 10GE switch of the front-end service network. A front-end storage network IP address is configured for each of the two ports.

NIC0

GE electrical port

Management network

The first three nodes of the OceanStor 9000 cluster provide management network ports.

You do not have to configure an independent IP address for any of the three nodes, because floating management IP addresses configured during the deployment are available to the nodes.

IPMI

FE electrical port

Management network

Connects to the CE5800 switch. A management and maintenance network IP address is configured for the port.

Networking Solution

Figure 4-10 shows the networking solution. OceanStor 9000 provides a pair of CE6800 switches for the front-end and back-end networks, as well as a CE5800 switch for the management network.

Figure 4-10  Networking diagram

Figure 4-11 shows the layout of ports on the CE6800 switches.

Figure 4-11  Layout of ports on the CE6800 switches

  • Downstream ports

    Each CE6800 switch uses three ports to connect to the back-end port of each node in sequence. If capacity expansion is required, assign ports 1 to 16 to VLAN A of the back-end storage network.

    • Switch CE6800-1 connects to port A0-0.
    • Switch CE6800-2 connects to port B3-0.
  • Upstream ports

    Each CE6800 switch uses three ports to connect to the front-end port of each node in sequence. If capacity expansion is required, you can assign ports 17 to 32 to VLAN B of the front-end service network.

    • Switch CE6800-1 connects to port A0-1.
    • Switch CE6800-2 connects to port B3-1.
  • Expansion ports

    Each CE6800 switch uses three ports as expansion ports, bonds them as Eth-trunk1, and connects it to the front-end service network. If capacity expansion is required, ports 33 to 48 can be included in VLAN B of the front-end service network.

  • Stacking ports

    The two CE6800 switches connect to each other using two stacking ports.

  • ETH management network ports

    ETH ports are used for switch management. The two ports connect to the CE5800 switch.

Figure 4-12 shows the layout of ports on the CE5800 switch.

  • IPMI downstream ports

    The three ports connect to node IPMIs in sequence. If capacity expansion is required, ports 1 to 16 can be used as downstream ports connected to nodes IPMIs.

  • Downstream NIC0 ports

    The three ports connect to the first three nodes (nodes 01 to 03 in the basic cabinet) of the OceanStor 9000 cluster in sequence.

  • 10GE switch management ports

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

  • Upstream ports

    Upstream ports connect to the customer's management and maintenance network.

  • 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 about the shutdown command, refer to the switch manual.
