Enhanced Link Mode (ELM)

vCenter Linked Mode provides the following capabilities for managing various vCenter instances:

• Offers a single management overview of multiple vCenter instances

• Provides a single login for multiple vCenter Server

• Shows a common inventory view and allows for searching of objects across vCenters.

• Replicates licenses, roles and permissions between vCenter instances.

There are two basic architectures for deploying vSphere 6.x:

• vCenter Server with an embedded Platform Services Controller (PSC).

• vCenter Server with External Platform Services Controller.

As a result of these architectures, Platform Services Controllers can be linked together. This enables an aggregate view of any vCenter Server that is configured to use the SSO domain. This feature is called Enhanced Linked Mode (ELM). Once you provide the connection details and SSO credentials for one of the ELM VCs, CloudControl will auto-discover all the VCs/PSCs.

vCenter Server with an Embedded Platform Services Controller is ideal for small environments.
