After you install the rack hardware for your AFF A1K storage system, install the network cables for the controllers, and connect the cables between the controllers and storage shelves.

Before you begin

Check the illustration arrow in the cabling diagrams for the proper cable connector pull-tab orientation.

Cable pull-tab orientation example

  • As you insert the connector, you should feel it click into place; if you do not feel it click, remove it, turn the cable head over and try again.

  • If connecting to an optical switch, insert the small form-factor pluggable (SFP) transceiver into the controller port before cabling to the port.

Step 1: Connect the storage controllers to your network

Connect the storage controllers to your host network.

Before you begin

Contact your network administrator for information about connecting your storage system to the switches.

About this task

These procedures show common configurations. Keep in mind that the specific cabling depends on the components ordered for your storage system. For comprehensive configuration and slot priority details, see NetApp Hardware Universe.

Option 1: Connect the controllers to a switchless ONTAP cluster

Connect your storage controllers to each other to create the ONTAP cluster connections, and then connect the Ethernet ports on each controller to your host network.

Steps

  1. Use the Cluster/HA interconnect cable to connect ports e1a to e1a and ports e7a to e7a.

    Note The cluster interconnect traffic and the HA traffic share the same physical ports.

    1. Connect port e1a on Controller A to port e1a on Controller B.

    2. Connect port e7a on Controller A to port e7a on Controller B.

  2. Connect the Ethernet module ports to your host network.

    The following are some typical host network cabling examples. See NetApp Hardware Universe for your specific system configuration.

    1. Connect ports e9a and e9b to your Ethernet data network switch as shown.

      Note For maximum system performance for cluster and HA traffic, do not use ports e1b and e7b ports for host network connections. Use a separate host card to maximize performance.

Option 2: Connect the controllers to a switched ONTAP cluster

Connect your storage controllers to the cluster network switches to create the ONTAP cluster connections, and then connect the Ethernet ports on each controller to your host network.

Steps

  1. Make the following cabling connections:

    Note The cluster interconnect traffic and the HA traffic share the same physical ports.

    1. Connect port e1a on Controller A and port e1a on Controller B to cluster network switch A.

    2. Connect port e7a on Controller A and port e7a on Controller B to cluster network switch B.

Step 2: Connect the storage controllers to the storage shelves

The following cabling procedures show how to connect your controllers to one shelf and to two shelves. You can directly connect up to four shelves to your controllers.

Option 1: Connect to one NS224 storage shelf

Connect each controller to the NSM modules on the NS224 shelf. The graphics show cabling from each of the controllers: Controller A cabling is shown in blue and Controller B cabling is shown in yellow.

Steps

  1. On controller A, connect the following ports:

    1. Connect port e11a to NSM A port e0a.

    2. Connect port e11b to port NSM B port e0b.

      Controller A e11a and e11b to a single NS224 shelf

  2. On controller B, connect the following ports:

    1. Connect port e11a to NSM B port e0a.

    2. Connect port e11b to NSM A port e0b.

      Cable controller B ports e11a and e11b to a single NS224 shelf

Option 2: Connect to two NS224 storage shelves

Connect each controller to the NSM modules on both NS224 shelves. The graphics show cabling from each of the controllers: Controller A cabling is shown in blue and Controller B cabling is shown in yellow.
