How to configure vSAN VMkernel networking (2058368)

  • 9 Ratings

Purpose

This article provides steps to configure the VMkernel network for vSAN (formerly known as Virtual SAN).

Resolution

Configuring vSAN VMkernel networking on a standard virtual switch

To configure vSAN VMkernel networking on a standard virtual switch:
  1. Open the vSphere Web Client.
  2. Go to the Hosts and Clusters view.
  3. Select the host you want to configure for vSAN.
  4. Click the Manage tab.
  5. Click Networking.
  6. Select VMkernel Adapters from the dropdown.
  7. Click the Add host networking icon and click Next.
  8. In the Select target device page, select either an existing standard switch or a new vSphere standard switch and click Next.

    Note: If you create a new standard switch, ensure that you attach sufficient physical NICs to the vSwitch.

  9. In the Port properties page, select Virtual SAN traffic, configure the settings for the VMkernel adapter, and enter appropriate values in these required fields:

    • Network label – Enter a label. For example, Virtual SAN.
    • VLAN ID – If you are using VLANs to separate vSAN traffic, enter the relevant VLAN ID.
    • IP Settings – Enter the desired IPv4 network details (DHCP, if applicable).
    • TCP/IP stack – Select the relevant TCP/IP stack.

      Notes:
      In vSphere 6.x, the network service is called Virtual SAN instead of Virtual SAN Traffic.
      For more information on multiple TCP/IP stacks, see the VMkernal Networking Layer section of the vSphere 6.0 Networking GuidevSphere 5.5 Networking Guide.

  10. Click Next.
  11. Review your settings, then click Finish.
  12. Repeat Steps 3 to 10 for each host that is a member of the vSAN cluster.
  13. After all hosts are configured, configure your vSAN Cluster. For more information, see Enabling or disabling a vSAN cluster (2058322).

Configuring vSAN VMkernel networking on a distributed virtual switch

To configure vSAN VMkernel networking on a distributed virtual switch:
  1. Open the vSphere Web Client.
  2. Go to the Networking view.
  3. Navigate to the distributed switch you want to modify
  4. Select Manage host networking and click Next.
  5. Click Attached hosts and select from the hosts that are associated with the distributed switch.
  6. Click Next.
  7. Select Manage VMkernel adapters and click Next.
  8. Click New adapter.
  9. In the Select target device page of the Add Networking wizard, select an existing distributed port group, and click Next.
  10. In the Port properties page, select Virtual SAN traffic, configure the settings for the VMkernel adapter, and enter appropriate values for these required fields:

    • Network label – Enter a label. For example, Virtual SAN.
    • VLAN ID – If you are using VLANs to separate vSAN traffic, enter the relevant VLAN ID.
    • IP Settings – Enter the desired IPv4 network details (DHCP, if applicable).
    • TCP/IP stack – Select the relevant TCP/IP stack.

      Note: In vSphere 6.x, the network service is called Virtual SAN instead of Virtual SAN Traffic.

  11. Click Next.
  12. Review your settings and then click Finish.

    You can now enable your vSAN cluster.
