vSphere with Tanzu uses the Default-Group Service Engine Group. Optionally, you can configure the Default-Group Service Engines within a group which defines the placement and number of Service Engine VMs within vCenter. You can also configure high availability if the NSX Advanced Load Balancer Controller is in Enterprise mode. vSphere with Tanzu supports only the Default-Group Service Engine. You cannot create other Service Engine Groups.

For information on how you can provision excess capacity in the event of a failover, see the Avi documentation.

Procedure

  1. In the NSX Advanced Load Balancer Controller dashboard, select Infrastructure > Cloud Resources > Service Engine Group .
  2. In the Service Engine Group page, click the edit icon in the Default-Group.
    The General Settings tab appears.
    vSphere with Tanzu only supports Default-Cloud.
  3. In the Placement section, select High Availability Mode.
    The default option is N + M (buffer). You can keep the default value or select one of the following options:
    • Active/Standy
    • Active/Active
  4. In the Service Engine section, you can configure excess capacity for the Service Engine group.
    The Number of Service Engines option defines the maximum number of Service Engines that may be created within a Service Engine group. Default is 10.
    To configure excess capacity, specify a value in the Buffer Service Engines. The value you specify is the number of VMs that are deployed to ensure excess capacity in the event of a failover.

    Default is 1.

  5. In the Virtual Service section, configure the following options.
    Option Description
    Virtual Services per Service Engine The maximum number of virtual services the Controller cluster can place on any one of the Service Engines in the group.

    Enter a value of 1000.
    Virtual Services Placement Across Service Engines Select Distributed. Selecting this option maximizes the performance by placing virtual services on newly spun-up Service Engines up to the maximum number of Service Engines specified. Default is Compact.
  6. You can keep the default values for the other settings.
  7. Click Save.
