In a typical Cloud Foundation environment, you will encounter specific VMware software that SDDC Manager deploys in the environment.

Licensed for use by the base Cloud Foundation license:

  • The SDDC Manager, the Hardware Management Services, and their subcomponents that provide centralized management of the Cloud Foundation software stack

  • The VMware software stack that implements a software-defined data center and which are deployed by SDDC Manager are:

    • vSphere

    • Platform Services Controller, used as the identity provider

    • Virtual SAN

    • NSX for vSphere

Separately licensed software components that are deployed by SDDC Manager are:

  • vCenter Server

  • vRealize Operations

  • vRealize Log Insight

  • VMware Horizon with View that provides virtual desktop infrastructure (VDI) environments

  • App Volumes

Note:

For information about which specific editions of each VMware product are licensed for use with the Cloud Foundation license, use the information resources at the Cloud Foundation product information page at http://www.vmware.com/products/cloud-foundation.html.

For the exact version numbers of the VMware products that you might see in your Cloud Foundation environment after the initial bring-up process, see the Release Notes document for your Cloud Foundation version. If the environment has been updated after the initial bring-up process using the Life Cycle Management features, see View Inventory Component Versions for details on how to view the versions of the VMware software components that are within your environment.

Caution:

Do not manually change any of the settings that SDDC Manager sets automatically by default. If you change the generated settings, like names of VMs, unpredictable results might occur. Do not change settings for the resources that are automatically created and deployed during workflows, the workload domain processes, assigned IP addresses or names, and so on.

Some of the default configuration settings can be customized using the SDDC Manager client. See Settings Configuration Using the SDDC Manager Client.

You can find the documentation for the following VMware software products and components at www.vmware.com/support/pubs:

  • vSphere

  • Platform Services Controller, used as the identity provider

  • vCenter Server

  • Virtual SAN

  • NSX for vSphere

  • vRealize Operations

  • vRealize Log Insight

  • View, a component of the VMware Horizon product

  • App Volumes

About the Primary Rack and the SDDC Manager Virtual IP Address

In a multirack Cloud Foundation installation, the primary rack is the one that:

  • Was the rack that went through the bring-up process first, the initial one in the installation

  • Has its ToR switches configured with uplink ports to carry traffic to your corporate network

  • Has the environment's three ISVM VMs and two Platform Services Controller VMs deployed on ESXi hosts in that rack

An instance of SDDC Manager is deployed on each physical rack as part of a managed cluster of services provided by the three ISVM VMs on the primary rack. Each of the SDDC Manager instances connects to those three ISVM VMs to read and write data. Even though each of those SDDC Manager instances has its own management IP address, a virtual IP (VIP) address is assigned to a network subinterface on one of the SDDC Manager instances. This VIP provides the convenience of having a single DNS name and IP address to connect to the SDDC Manager client.

Usually, the primary rack's SDDC Manager instance is assigned the VIP address because the VIP address gets created during the bring-up process on the initial rack in an installation. However, there are situations in which you will find the VIP address is assigned to one of the other racks' SDDC Manager instances. Whenever the vrm-tcserver service is stopped in the SDDC Manager instance having the VIP address, the VIP address is automatically reassigned to the next rack's SDDC Manager instance. For example, if the instance that has the VIP address is rebooted, the VIP address is automatically reassigned to another SDDC Manager instance. As a result, the primary rack is not always the same rack having the SDDC Manager instance with the VIP address.

When you view the domain details for any of the management domains using the SDDC Manager client, the SDDC Manager VIP address is displayed in the domain details screens, in the table labeled VMware Cloud Foundation Management Components. For the SDDC Manager instance on a given rack, you can determine if the VIP is assigned to it by logging in to that rack's SDDC Manager instance using the root account and issuing the ifconfig command:

rack-1-vrm-1:~ # ifconfig

When the VIP is assigned to that instance, the ifconfig commands output lists an eth0:1000 subinterface with the VIP address assigned to the subinterface's inet addr.
