Installing vCenter Appliance 6 -Part 1 – Platform Service Controller

Brief Info on PSC


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.

Additionally it provides the following services

  • License service (formerly held by vCenter)
  • Single Sign-on Service (Secure Token Service, identity management service, directory service)
  • Lookup Service
  • VMware Certificate Authority (VMCA)
  • VMware Endpoint Certificate Store (VECS)
  • Authentication framework daemon
  • Component Manager Service (CM)
  • HTTP reverse proxy

You can embed the PSC into the vCenter Appliance but there is no migration route then to a standalone PSC which provides greater scale ability and flexability. There currently no HA for the PSC role, so an external services such as F5 or Netscaler would have to be used (see the image at the top of this post). I recommend a standalone PSC and vCenter running on a second VM.

Think about the role seperation between the two as follows;
