The virtual infrastructure design includes the software components that make up the virtual infrastructure layer and that support the business continuity of the SDDC.
These components include the software products that provide the virtualization platform hypervisor, virtualization management, storage virtualization, network virtualization, and backup. VMware products in this layer include VMware vSphere, VMware vSAN, VMware NSX, and vSphere Data Protection.
Virtual Infrastructure Design Overview
The consolidated SDDC virtual infrastructure consists of a single region. This region includes a consolidated pod which consists of management, edge and compute workloads.
The consolidated pod runs the following services:
Virtual machines to manage the SDDC such as vCenter Server, NSX Manager, vRealize Automation, vRealize Log Insight, vRealize Operations Manager and vSphere Data Protection.
Required NSX services to enable north-south routing between the SDDC and the external network, and east-west routing inside the SDDC.
SDDC tenant virtual machines to support workloads of different Service Level Agreements (SLAs).
Because this pod supports all SDDC, network, and production workloads, it is important to ensure highly available physical components such as HVAC, power feeds and power supplies.
