vcenter

I’ve always tried to use and recommend using the ‘least privileges’ model when designing and implementing systems. But we’ve all been there, when the same service account is being used to connect everything to vCenter, and said account has been assigned the full administrator role and propagated within vCenter. I’m getting my lab set up again and I needed to install VMware Update Manager (VUM). I realised that in the lab previously I have just done as I mentioned before and used a high privilege service account thinking “it’s just a lab”.

A long last, VMware have made a tool available and supported to migrate from a Windows installation of vSphere 5.5 across to the vCenter Server Appliance (VCSA) 6.0U2. VMware gave us a teaser with a fling in 2015, but this was taken down and there have been hints dropped via Social Media and most recently some good sessions for the migration tool at VMworld 2016. Prior to this tool, migrating from a Windows install to the VCSA was not a trivial task.

Introduction This article will walk through the steps required to repoint a vCenter Server 6U1 or later node to a different Platform Services Controller (PSC) node. Scenario one will walk through the steps if the destination PSC is located within the same vSphere SSO site, where as scenario two will walk through the steps if the destination PSC is located in a different vSphere SSO site. This is almost the same process, but repointing a VC to a PSC in a different SSO Site than the original PSC requires an additional step.

Introduction Starting with vSphere 6, there are two main roles to a core vCenter infrastructure. The vCenter Server (VC) and the Platform Services Controller (PSC). During deployment, administrators are presented with two deployment options: Embedded. With an embedded deployment, the VC and PSC roles are installed on the same node External. With an external deployment, the PSC and VC roles are installed onto separate nodes. External deployment also enables the enhanced linked mode feature for vCenter Server Prior to 6.

In the busy world we live in, a lot can be said for the “time flies when you’re having fun” saying. And with so much happening in the world of the SDDC, it’s easy to forget about some of the core components that, for the most part, sit there reasonably quietly just ‘doing their thing’. This is just a quick reminder post for those still running vSphere 5.0 or 5.1, that end of general support ends for those products this week, on the 24th of August to be exact.

In my lab, I deployed vCenter using the appliance as an embedded node using vCenter 6.0.0b. I purposely deployed this build, as an embedded deployment for two reasons: I haven’t used the appliance before, and I wanted the lab to be simple, but I also wanted to see the upgrade process in action on the appliance I wanted to deploy an external PSC and follow the process to re point the original VC server to the new external PSC, as outlined here: http://pubs.
