In my last post I gave an introduction to the VMware Validated Design PODs – Management POD, Edge POD and Compute POD. In this post I’d like to go over each of these PODs in a more detail.
Every IT infrastructure has a basic set of infrastructure components needed to instantiate the environment. In the VMware Validated Design, these infrastructure components go into what is called the Management POD. In both the Data Center Foundation and IT Automation Cloud, the Management POD is comprised of a minimum of four ESXi hosts. These four hosts are configured in a vSphere cluster with HA and DRS both enabled. Hence you will often see the Management POD referred to as a Management Cluster. Storage for the Management Cluster is provided using VSAN, which is nice as it eliminates any dependency on an external storage subsystem, while still providing a high-performing and highly scalable storage solution. It is on this management cluster that we run all the SDDC “infrastructure” components, to include, but by no means limited to the: Platform Services Controller, vCenter Server, NSX Manager, NSX Controllers, etc. Additional infrastructure components are also typically run on the Management Cluster, these can include Active Directory, DNS, DHCP and the like.
