Connecting a Signal Cable for a P25E/P36E/P12E/C36E Node (IB Network)

Connecting a Signal Cable for a P25E/P36E/P12E/C36E Node (IB Network)

When IB switches are used on both the front-end network and back-end network of OceanStor 9000, storage nodes connect to IB switches using signal cables.

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 IB switches are used on both the front-end network and back-end network of OceanStor 9000, ports on storage nodes are shown in Figure 10-41 and their usage is described in Table 10-19.

Access Network

Description

SLOT4-0 and SLOT5-0

40GE QSFP+ Ethernet optical port

Back-end network

The nodes connect to the two SX6018 IB switches through FDR cables.

SLOT4-1 and SLOT5-1

40GE QSFP+ Ethernet optical port

Front-end network

Connects to the IB switches on the user's network using optical fibers.

NIC1

GE electrical port

Management and maintenance network

Connects each NIC1 port on the bottom three nodes to the GE switch in the basic cabinet using network cables.

Mgmt

FE electrical port

Management and maintenance network

Connects to the GE switches in the basic cabinet using network cables.

The front-end service network uses 100Gb IB network (only supported by P25E/P36E)

Figure 10-42 shows the ports on nodes.

Figure 10-42  Port layout

Table 10-20 describes ports used by nodes when the front-end service network uses 100Gb IB network and the back-end storage network uses 56Gb IB network.

Description

SLOT7-0 and SLOT7-1

100Gb IB port

Front-end service network

The two ports are used to connect to 100Gb IB switches on the front-end network and each of them is assigned one front-end service network IP address.

SLOT4-0 and SLOT4-1

56Gb IB port

Back-end storage network

The two ports are used to connect to 56Gb IB switches on the back-end network and each of them is assigned one back-end storage network IP address.

NIC1

GE electrical port

Management network

The first three to five nodes in an OceanStor 9000 cluster provide management and maintenance ports, which connect to S5752/CE5800 switches.

You do not need to configure an independent IP address for the three nodes. The management IP addresses configured during the OceanStor 9000 deployment automatically float to one of those ports.

Mgmt

Ethernet port

Management network

The Mgmt port connects to an S5752/CE5800 switch and is assigned one management network IP address. The Mgmt port IP address and the cluster management IP address must be on the same network segment.

Switch Port Planning

Ports on an SX6018 IB switch in a cabinet are shown in Figure 10-43, and their usage is described in Table 10-21.

QSFP+ port

Back-end network

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

  • Switch SX6018-01 connects to SLOT4-0 on each storage node.
  • Switch SX6018-02 connects to SLOT5-0 on each storage node.

17 and 18

QSFP+ port

-

Connects two SX6018 switches.

In the basic cabinet, the S5752/S5352/CE5855 GE switch ports for connecting to the management and maintenance network are shown in Figure 10-44 and Figure 10-45, and the port usage is described in Table 10-22.

10/100/1000BASE-T Ethernet port

Management and maintenance network

Connects to Mgmt ports on storage nodes in sequence.

45, 46, and 47

Connects to NIC1 ports on the first three nodes (nodes 01 to 03 in the basic cabinet) in the OceanStor 9000 cluster in sequence.

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. Optional: Install an optical module.

    • Wear an ESD wrist strap or gloves to prevent damaging ESD-sensitive optical modules.
    • Do not insert an optical module reversely. If an optical module cannot be completely inserted into an optical module slot, do not force it into the slot. Turn the optical module over and try again.
    • Do not remove dust-proof caps from optical connectors before connecting optical fibers to optical modules.
    • Optical modules and optical fibers support only multi-mode 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 10-46.

      When the locking reed of the optical module makes a "click" sound, the optical module is installed correctly.

      Figure 10-46  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 10-47.
      Figure 10-47   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 example shown in Figure 10-48, IB switches are used on both the front-end and back-end networks, and three P25E nodes are deployed.

NOTE:

The nodes connect to the two SX6018 IB switches through FDR cables.
