Connecting FCoE Front-end Ports

Connecting FCoE Front-end Ports

Connect FCoE front-end ports on a controller enclosure to ports on an application server through optical fibers so that service channels are set up for data exchange between the storage device and the application server.

Prerequisites

The required installation tools and materials include:

  • 10 Gbit/s optical module
  • Optical fiber
  • Fiber binding straps
  • Diagonal pliers

Context

Two-port FCoE interface modules only support direct-connection networks. Four-port FCoE interface modules only support switch-based networks. When SmartIO interface modules are set to the FCoE mode, the networking mode is the same as that of four-port FCoE interface modules. The following network diagram uses a four-port FCoE interface module as an example.

A SmartIO interface module supports three working modes: FC, FCoE/iSCSI, and Cluster. When the mode of a SmartIO interface module is set to FCoE, only Intel DCBX (CEE) mode is supported. In this case, set the interconnected switch to the Intel DCBX (CEE) mode. For details about how to query and modify the mode, see the switch product documentation.

When connecting a port on an application server directly or through an Ethernet switch, an FCoE front-end port equals a 10GE front-end port. The method for connecting the FCoE port is the same as the method for connecting a 10GE electrical interface module.

Figure 6-51 shows two typical network topologies for connection with application servers through an FCoE switch.

NOTE:

The data types supported by each of the following typical network topologies are different. Moreover, the network elements (NEs) must be configured correctly to set up a valid connection. For details about how to correctly configure the storage system, see Initially Configuring the Storage System. For details about how to correctly configure the application server or FCoE switch, refer to relevant product documents.

Figure 6-51 Connection from FCoE ports to application servers through an FCoE switch
NOTE:

A 10 Gbit/s optical module does not support the 1 Gbit/s rate.

Do not look into an optical port without eye protection.

When connecting optical fibers, note the following:

  • An optical module is electrostatic sensitive and must be placed in an ESD-resistant and dust-proof environment during transportation, storage, and use.
  • When connecting cables, select proper cables according to site requirements and label information.
  • An optical fiber connector must be kept clean and free from scratches.
  • Cover unused optical fibers and optical modules with protective caps.
  • The bend radius of the optical fiber should be larger than 5 cm (1.97 inches).

Procedure

  1. Wear an ESD wrist strap, ESD gloves, and ESD clothes.
  2. (Optional) Install an optical module into a 10 Gbit/s FCoE front-end port on the controller enclosure.

    NOTE:

    If the optical module is already inserted into the FCoE front-end port, go to Step 3.

    1. Remove the protective cap from the optical module, as shown in step 1 of Figure 6-52.
    2. Insert the optical module into the FCoE front-end port on the controller enclosure, as shown in step 2 of Figure 6-52.
    NOTE:

    Insert the optical module horizontally; otherwise, the module may be damaged.

    Figure 6-52 Installing an optical module

  3. Remove the protective caps from the connectors of the optical fibers, as shown in step 1 of Figure 6-53.
  4. Insert an optical fiber into the 10 Gbit/s FCoE front-end port on the controller enclosure, as shown in step 2 of Figure 6-53.

    NOTE:

    The optical fiber is securely installed into the optical module when a click is heard.

    Figure 6-53 Connecting optical fibers

  5. Connect the other end of the optical fiber to the switch, and connect the switch to an application server.
  6. Route and bind the optical fibers.

    NOTE:

    For details about routing and bundling principles, see General Cable Routing Principles and Cable Routing and Bundling Basics.
