Connecting Signal Cables for a 5288 V5 36-Slot Node or 2288H V5 12-Slot Node

This section describes how to connect a node to a switch in a 10GE network.

Prerequisites

  • Information about the current network and associated ports has been obtained.
NOTE:

For details about networking and port connection, see FusionStorage OBS Planning Guide of the desired version.

  • 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, ESD gloves or an ESD wrist strap, optical fibers, and network cables.

2288H V5 12-Slot Node

Figure 10-1 shows the network ports of a storage node.

Figure 10-1 Network ports
NOTE:
  • The storage node can be configured with 2-port 10GE/25GE PCIe cards or 4-port GE PCIe cards.
  • The management plane can independently use the NIC network port as the management network port, or share the SLOT physical network port with the service plane. An independent VLAN is configured for each plane. This section describes the storage node ports used when the management plane independently uses network port NIC as the management network port.

Table 10-1 lists storage node ports used when the service plane uses GE networks, and the storage/control plane uses the 10GE network.

Ports on Switches for Networking

The following uses six storage nodes as an example to describe the physical connection rules of switches.

Figure 10-3 shows an example of planning ports on a 48-port CE6855 switch (10GE switch, CE6800 for short), and Table 10-5 describes port usage.

Description

10GE optical ports

1 to 12

Storage node ports

Each CE6800 switch uses twelve 10GE ports to sequentially connect to each node.

  • Switch CE6800-1 connects to port SLOT1-0 on each node.
  • Switch CE6800-2 connects to port SLOT1-1 on each node.

13 to 44

Reserved ports

Reserved ports are the ports reserved for future use. To prevent adverse impact on other ports, you are advised to run the shutdown command to disable all reserved ports. For details about the shutdown command, refer to related switch documentation.

45 to 48

Stack ports

Two CE6800 switches are stacked using four 10GE ports.

40GE optical ports

1 to 6

Aggregation ports

Each switch uses six 40GE ports to connect to the aggregation switch.

ETH management network ports

Used to manage switches. The two ports connect to the BMC/management network switch (CE5855).

Figure 10-4 shows an example of planning ports on a 48-port CE5855 switch (GE switch, CE5800 for short), and Table 10-6 describes port usage.

NIC1 ports

The CE5800 switch connects to the NIC1 port of each node through 6 Ethernet ports.

7 to 45

Reserved ports

Reserved ports are the ports reserved for future use. To prevent adverse impact on other ports, you are advised to run the shutdown command to disable all reserved ports. For details about the shutdown command, refer to related switch documentation.

46 to 48

Switch management ports

Switch management ports connect to the ETH management network ports on the front of the two CE6800 switches.

1 and 2

Upstream aggregation ports

Each CE5800 switch connects to upstream aggregation switches through two Ethernet ports.

NOTE:
  • If the number of planned nodes does not exceed the specifications of a single cabinet, use a single cabinet. Accordingly, two 10GE switches are deployed in the same cabinet. Each node is connected to two 10GE switches in the base cabinet through optical fibers and optical modules.
  • If the number of planned nodes exceeds the specifications of a single cabinet, use multiple cabinets. Accordingly, one 10GE switch is deployed in a basic cabinet, and another 10GE switch in an expansion cabinet. Each node is connected to the 10GE switch in the local cabinet and that in the other cabinet through optical fibers and optical modules.

Procedure

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

    • Wear an ESD wrist strap or ESD gloves to prevent damaging ESD-sensitive optical modules.
    • Do not reversely insert optical modules. If an optical module cannot be inserted into an optical port, do not force it in. In this case, turn it over and try again.
    • Do not remove dust-proof caps from optical connectors before connecting optical fibers to optical modules.
    1. Take out an optical module from its 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 10-5.

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

    Figure 10-5 Installing an optical module

  5. Connect cables according to the attached labels.

    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 10-6, three storage nodes are deployed.
