What’s New in #vSphere 6.0: Enhanced Linked Mode

VMware has finally officially announced what is to be included in 6.0 after lifting the lid on parts of the update during VMworld 2014 keynotes and sessions. 

See my introductory post: What’s New in vSphere 6.0: Finally Announced (about time!) for details of all the components.

vCenter Linked Mode provides a single management overview of multiple vCenter instances.

Linked Mode also provides a single login for multiple vCenter Servers and then shows you a common inventory view and allows you to search for objects across vCenters. Licenses, roles and permissions are replicated between vCenter instances.

Linked mode has always been only available for Windows vCenters (ADAM is used as the replication engine) so you couldn’t share licenses, roles and permissions with any vCenter appliances you had.

With the release of the new Platform Services Controller in vSphere 6.0, some of the Linked Mode functionality is changing and its been given a new same.

vSphere will also now include an Enhanced Linked Mode which will require and work in conjunction with the Platform Services Controller.

This will not rely on ADAM but have its own replication system which is a multi-master replication technology also called VMDir based on Open LDAP which means replication now works across Windows vCenter as well as vCenter appliances.

Replication will be expanded to include Policies and Tags along with Roles and Permissions. In fact the replication engine will allow VMware to sync any kind of information between Platform Services Controllers which can then be used by vCenters and other management products. Bye bye ADAM, you won’t be missed.
