Configure storage array NVMe over RoCE connections

Contributors NetAppZacharyWambold netapp-jolieg

If your controller includes a connection for NVMe over RoCE (RDMA over Converged Ethernet), you can configure the NVMe port settings from the Hardware page or the System page in SANtricity System Manager.

What you’ll need
  • An NVMe over RoCE host port on your controller; otherwise, the NVMe over RoCE settings are not available in System Manager.

  • The IP address of the host connection.

About this task

You can access the NVMe over RoCE configuration from the Hardware page or from Settings  System. This task describes how to configure the ports from the Hardware page.

Note The NVMe over RoCE settings and functions appear only if your storage array’s controller includes an NVMe over RoCE port.
Steps
  1. From the System Manager interface, select Hardware.

  2. Click the controller with the NVMe over RoCE port you want to configure.

    The controller’s context menu appears.

  3. Select Configure NVMe over RoCE ports.

    The Configure NVMe over RoCE ports dialog box opens.

  4. In the drop-down list, select the port you want to configure, and then click Next.

  5. Select the port configuration settings you want to use, and then click Next.

    To see all port settings, click the Show more port settings link on the right of the dialog box.

    Port Setting Description

    Configured ethernet port speed

    Select the desired speed. The options that appear in the drop-down list depend on the maximum speed that your network can support (for example, 10 Gbps). Possible values include:

    • Auto-negotiate

    • 10 Gbps

    • 25 Gbps

    • 40 Gbps

    • 50 Gbps

    • 100 Gbps

    • 200 Gbps

    Note When a 200Gb-capable HIC is attached with a QSFP56 cable, auto-negotiate is only available when you are connecting to Mellanox switches and/or adapters.
    Note The configured NVMe over RoCE port speed should match the speed capability of the SFP on the selected port. All ports must be set to the same speed.

    Enable IPv4 and/or Enable IPv6

    Select one or both options to enable support for IPv4 and IPv6 networks.

    MTU size (Available by clicking Show more port settings.)

    If necessary, enter a new size in bytes for the maximum transmission unit (MTU). The default MTU size is 1500 bytes per frame. You must enter a value between 1500 and 4200.

    If you selected Enable IPv4, a dialog box opens for selecting IPv4 settings after you click Next. If you selected Enable IPv6, a dialog box opens for selecting IPv6 settings after you click Next. If you selected both options, the dialog box for IPv4 settings opens first, and then after you click Next, the dialog box for IPv6 settings opens.

  6. Configure the IPv4 and/or IPv6 settings, either automatically or manually. To see all port settings, click the Show more settings link on the right of the dialog box.

    Port setting Description

    Automatically obtain configuration from DHCP server

    Select this option to obtain the configuration automatically.

    Manually specify static configuration

    Select this option, and then enter a static address in the fields. For IPv4, include the network subnet mask and gateway. For IPv6, include the routable IP addresses and router IP address.

    Note If there is only one routable IP address, set the remaining address to 0:0:0:0:0:0:0:0.

    Enable VLAN support (Available by clicking Show more settings.)

    Note This option is only available in an iSCSI environment. It is not available in an NVMe over RoCE environment.

    Enable ethernet priority (Available by clicking Show more settings.)

    Note This option is only available in an iSCSI environment. It is not available in an NVMe over RoCE environment.
  7. Click Finish.
