List of recommended topologies for VMware vSphere 6.0

Products

• VMware vCenter Server

Issue/Introduction

This article discusses the possible join operation combinations with VMware recommendations.

During installation or upgrading of vCenter Server 6.0, you can:

• Join a vCenter Server with an external Platform Services Controller to a Platform Services Controller.
• Join an external Platform Services Controller to a Platform Services Controller.

These join operations are intended for external Platform Services Controllers. However, the installer does not validate whether the Platform Services Controller is external or embedded with vCenter Server.

Though many types of join operations are possible, not all resulting configurations are recommended.

For vSphere 6.5, see Supported and deprecated topologies for VMware vSphere 6.5 (2147672).

Deprecated topologies

Topologies that are deprecated and will be unsupported in the future. These topologies are not recommended:

Composition	Backup process supported
1 Single Sign-On domain 1 or more Single Sign-On sites 2 or more vCenter Server with embedded Platform Services Controller	None
1 Single Sign-On domain 1 or more Single Sign-On sites 0 external Platform Services Controllers 1 or more vCenter Server with external Platform Services Controllers 1 or more vCenter Server with embedded Platform Services Controller	None
1 Single Sign-On domain 1 or more Single Sign-On sites 1 or more external Platform Services Controllers 1 or more vCenter Server with external Platform Services Controllers 1 or more vCenter Server with embedded Platform Services Controllers	None

Changing topology

Migrations:

• Migrating two VMware vCenter Single Sign-On embedded VMware vCenter Servers in the same VMware vCenter Single Sign-On domain (2130433)
  
• Migrating a single VMware vCenter Single Sign-On embedded VMware vCenter Server deployment to an external VMware vCenter Single Sign-On deployment (2127992)
  
• Migrating a VMware vCenter Single Sign-On embedded VMware vCenter with a VMware vCenter Server node in the same VMware vCenter Single Sign-On domain (2128430)

Installations:

When performing one of these operations:

• Joining a vCenter Server with an external Platform Services Controller to a Platform Services Controller during installation or upgrading
• Joining an external Platform Services Controller to a Platform Services Controller during installation or upgrading

The installer displays a warning that these types of join operations cannot be changed after the installation or upgrading process. If you have deployed one of the topologies that are not recommended, the operation cannot be undone. You are required to re-install vSphere 6.0 using one of the preceding listed recommended topologies.

• Moving an ESXi/ESX host with vDS from one vCenter Server to another (1029498)

Upgrades:

There are several configurations of vSphere 5.1 and 5.5 that may be upgraded to one of the topologies that are not recommended. These include, but are not limited to:

• Two or more vCenter Server and vCenter Single Sign-On (SSO) services installed on the same machine on the same SSO domain.
• An environment with these servers on the same SSO domain:
  • One or more vCenter Server and vCenter SSO installed on the same machine
  • One or more vCenter SSO installed on a dedicated machine
  • One or more vCenter Server on a dedicated machine

If you have one of the preceding vSphere 5.1 or 5.5 topologies, you may be required to do one of these options:

• Re-install the vSphere 5.1 or 5.5 using one of the recommended topologies in advance of the upgrade. For information on registering components in this method, see Re-pointing and re-registering VMware vCenter Server 5.1 / 5.5 and components (2033620).
• Install vSphere 6.0 using one of the preceding recommended topologies.
