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, and network virtualization. The VMware products in this layer are vSphere, vSAN, and NSX for vSphere.
Virtual Infrastructure Design Overview
The consolidated cluster runs the following services:
Virtual machines to manage the ROBO SDDC such as vCenter Server, NSX Manager, vRealize Log Insight cluster, vRealize Operations Manager remote collectors, vRealize Automation vSphere agents, and vRealize Business data collectors.
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 cluster supports all SDDC, network, and production workloads, it is important to ensure highly available physical components such as HVAC, power feeds and power supplies.
