Connecting a Signal Cable for a P25E/P36E/P12E/C36E (10GE Network)

Connecting a Signal Cable for a P25E/P36E/P12E/C36E (10GE Network)

When 10GE switches are used on both the front-end network and back-end network of OceanStor 9000, storage nodes (P25E/P36E/P12E/C36E) connect to 10GE switches using 10GE signal cables. This section introduces the network of switches CE6855-48S6Q-HI (CE6800 for short). The networks of switches CE6810-24S2Q-LI, CE6810-48S4Q-EI and CE6851-48S6Q-HI are similar.

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 10GE switches are used on both the front-end network and back-end network of OceanStor 90000, ports on P25E/P36E/P12E/C36E are as shown in Figure 10-8 and Table 10-4 describes their usage details.

Description

SLOT4-0 and SLOT5-0

10GE SFP+ Ethernet optical port

Back-end network

  • The basic cabinet is equipped with two CE6800 switches. The nodes in the basic cabinet connect to the two switches through SPF+ cables.
  • Each of the first two cabinets is equipped with one CE6800 switch. The nodes in cabinets where switches are installed connect to the switches in their own cabinets through SFP+ cables. The nodes in cabinets where no switches are installed connect to the switches through optical fibers.

SLOT4-1 and SLOT5-1

10GE SFP+ Ethernet optical port

Front-end network

Connects to the 10GE 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 one network cable.

Mgmt

GE electrical port

Management and maintenance network

Connects the Mgmt port on each storage node to the GE switch in the basic cabinet using one network cable.

Switch Port Planning

Figure 10-9 shows ports on a CE6800 10GE switch in a cabinet, and Table 10-5 describes their usage.

10GE SFP+ Ethernet optical port

Back-end network

Each CE6800 switch connects to storage nodes using 40 ports in sequence.

  • Switch CE6800-1 connects to SLOT4-0 on each node.
  • Switch CE6800-2 connects to SLOT5-0 on each node.

Stack ports are used in the sequence from 1 to 4. The usage principles are as follows:

  • When the number of nodes is not larger than 16, use at least two stack ports.
  • When the number of nodes is larger than 16 but not larger than 24, use at least three stack ports.
  • When the number of nodes is larger than 24 but not larger than 40, use at least four stack ports.

10/100/1000BASE-T Ethernet port

Management and maintenance network

Connects to the GE switch.

In the basic cabinet, the S5752/S5352/CE5855 GE switch ports for connecting to the management and maintenance network are shown in Figure 10-10 and Figure 10-11, and the port usage is described in Table 10-6.

Management and maintenance network

Connects to Mgmt ports on storage nodes in sequence.

42, 43, and 44

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

45 and 46

Connects to ETH management network ports on the two CE6800 switches.

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 10-12.

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

      Figure 10-12  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 10-13.
      Figure 10-13   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 10-14, if the front-end and back-end use 10GE networks, three P25E nodes are deployed.

NOTE:

The nodes in cabinets where switches are installed connect to the switches in their own cabinets through . The nodes in cabinets where no switches are installed connect to the switches through optical fibers.
