Connecting Signal Cables Between Devices (Front-End 10GE Network + Back-End IB Network)

Connecting Signal Cables Between Devices (Front-End 10GE Network + Back-End IB Network)

When 10GE switches are used on the front-end network and IB switches are used on the back-end network, storage nodes connect to switches through signal cables. This section describes how to connect a CE6810-48S4Q-EI switch. You can use the same method to connect a CE6810-24S2Q-LI switch.

Prerequisites

  • Information about the current network and associated ports has been obtained.
  • Required components have been installed in the cabinet.
  • PGND cables and power cables have been connected to the components in the cabinet.
  • All required tools have been prepared, containing cable ties, diagonal pliers, and ESD gloves or an ESD wrist strap.

Storage Node Port Planning

When the front-end network uses GE network and the back-end network uses 10GE network of OceanStor 9000, ports on storage nodes are shown in Figure 10-61 and their usage is described in Table 10-28.

Access Network

Description

B3-0 and B3-1

10GE SFP+ Ethernet optical port

Front-end network

Connects to the 10GE switches on the user's network through optical fibers.

A0-0 and A0-1

40GE QSFP+ Ethernet optical port

Back-end network

Connects to the two IB switches in the basic cabinet through QSFP+ high-speed cables.

NIC0

GE electrical port

Management and maintenance network

Connects each NIC0 port on the bottom three nodes in the basic cabinet to the S5752/S5352 switch through one network cable.

IPMI

FE electrical port

Management and maintenance network

Connects to the S5752/S5352 switches in the basic cabinet through network cables.

Switch Port Planning

Ports on an SX6018 IB switch in a cabinet are shown in Figure 10-62, and their usage is described in Table 10-29.

40GE SFP+ Ethernet optical port

Back-end network

Each SX6018 switch connects to nodes through 16 ports in sequence.

  • SX6018-01 connects to A0-0 of each storage node.
  • SX6018-02 connects to B3-0 of each storage node.

Connects two SX6018 switches.

In the basic cabinet, the S5752/S5352 GE switch ports for connecting to the management and maintenance network are shown in Figure 10-63, and the port usage is described in Table 10-30.

Management and maintenance network

Connect to IPMI ports on storage nodes in sequence.

45, 46, and 47

Connect to NIC0 ports on the first three nodes (nodes 01 to 03 in the basic cabinet) in OceanStor 9000.

48

Connects to the user's management and maintenance network.

Procedure

  1. Wear an ESD wrist strap or ESD gloves.
  2. Determine port numbers of the storage node and signal cable connection modes.
  3. Obtain the required types of cables and label them.
  4. Install an optical module.

    • Wear an ESD wrist strap or gloves to prevent damaging ESD-sensitive optical modules.
    • Do not push an optical module hard if it fails to easily sit in the optical subcard. Try to reversely insert it.
    • Do not remove dust-proof caps from optical connectors before connecting optical fibers to optical modules.

    1. Take out an optical module from an ESD bag and verify that the optical module is intact.
    2. Insert the optical module into an optical port on the subcard until it snaps into place and then raise the handle to lock it up, as shown in Figure 10-64.

      Figure 10-64  Installing an optical module

  5. Connect cables according to the attached label.

    • To connect a copper cable, hold a copper cable connector in a correct direction when inserting it into a port. When you hear a click, the copper cable is securely connected to the port.
    • To remove a copper cable, gently push the cable connector and then pull the handle of the connector. Do not directly pull the cable connector with force, as shown in Figure 10-65.
      Figure 10-65   Removing a copper cable

    • After connecting cables to the devices, reserve adequate cable slack for ease of operation on other FRUs.

  6. Lay out the cables along the mounting bars neatly, use cable ties to bind them, and trim off the excess of cable ties using diagonal pliers.

Example

In the following example, there are three P25 nodes deployed, and 10GE switches are used on the front and IB switches are used on the back-end network.
