We’ve covered three blog posts (1, 2, 3) so far and vCenter Server being one of the most crucial components deserves a bit more attention! Since the announcement of vSphere 6, there has been a lot of cool changes to the underlining architecture of vCenter, and we covered a bit in the previous blog post when we discussed Platform Services Controller and Management Node. But we didn’t really get into much detail. With this post, I’d like to talk a bit more about the new vCenter architecture and hopefully helping my readers in better understanding the new functionality so that they can make the right choices when deploying the new vCenter Server.
- Deploying vSphere 6.0 – ESXi Installation – Part 1
- Deploying vSphere 6.0 – vCenter Server Installation – Part 2
- Deploying vSphere 6.0 – vCenter Server Appliance Installation – Part 3
- Deploying vSphere 6.0 – Platform Services Controller – Part 4
What’s New? Platform Services Controller (PSC) and Management Node deployment make up the vCenter installation!!!!
Let’s begin by discussing Platform Services Controller (PSC). PSC contains many services that will essentially be used by most VMware products like vCenter, vRealize (formerly vCOPs), vCloud Director, etc . The PSC itself will be able to replicate with another PSC server for redundancy and high availability purposes. One interesting aspect to consider is that by default, when deploying vCenter server, Linked Mode will be enabled, this is because PSC will replicate all the required information without any special configuration.
When looking at what PSC is responsible for, we see that the main services that PSC will mange include:
- Single Sign On (SSO)
- Certificate Management (VMware Certificate Authority and VMware Endpoint Certificate Store)
- Identity Management
Now we also have the Management Node. This particular part takes care of the following services:
- Auto Deploy
- vCenter Server
- Web Client
- Inventory Service
- Profile Driven Storage
- So on…
One interesting aspect to the new vCenter server deployment is certificate management, more specifically VMware Certificate Authority, which essentially assists with the management of objects like ESXi hosts.
There’s a lot of good information coming from these bloggers so I won’t go into too much detail as they did a great job of outlining the new features of PSC:
