VMware SDDC Manager configures the first three servers in each rack into a management domain. It is recommended that you expand the management domain to four servers to provide added redundancy and to facilitate vSAN maintenance. The management domain hosts all the VMware Cloud Foundation infrastructure components.

Management Domain
A VMware Cloud Foundation Virtual Infrastructure (VI) Workload Domain is a logical partition within the private cloud representing a subset of CPU, memory and storage capacity, allocated to an individual business unit or tenant that is used to deliver virtual infrastructure. Each VI workload domain implements a separate instance of the VMware SDDC software
stack to include vCenter Server, ESXi, vSAN, and NSX.

A VMware Cloud Foundation Virtual Desktop Infrastructure (VDI) Workload Domain is a logical partition within the private cloud representing a subset of CPU, memory and storage capacity allocated to a business unit or tenant that is used to deliver virtual desktops. Each VDI workload domain implements a separate instance of the VMware SDDC software
stack to include vCenter Server, ESXi, vSAN, and NSX together with Horizon View.
vSAN Ready NodesVMware Cloud Foundation use rack mount vSAN Ready Nodes to ensure seamless compatibility and support. The configuration and
assembly for each node is standardized with all components installed the same manner to eliminate system variability. vSAN enables both hybrid and all-flash architectures.

VMware Cloud Foundation is VMware's unified SDDC platform for the private and public clouds. VMware Cloud Foundation brings together VMware’s compute, storage, and network virtualization into a natively integrated stack, delivering enterprise-ready cloud infrastructure with unique
automation and management capabilities for simplified operations that is consistent across private and public clouds.

VMware Cloud Foundation is an integrated suite of software components. These components include the unified SDDC platform, which includes VMware vSphere, vSAN and NSX, together with the VMware SDDC Manager. Optional components,
such as vRealize Suite and Horizon Suite, can also be included.

SDDC Manager
A VMware Cloud Foundation private cloud deployment is comprised of between one to eight physical racks. Each rack contains between 8 to 32 vSAN Ready Nodes, one management switch, and two Top-of-Rack (ToR) switches. In multi-rack configurations, a pair of redundant spine switches are added to the second rack to provide for inter-rack connectivity.

SDDC ManagerSDDC Manager is a virtual appliance running in the management domain that provides a single point-of-control for the management and
administration of Cloud Foundation. SDDC Manager interfaces with the Hardware Management Service and vCenter server to provide centralized access along with an integrated view of both the physical and virtual infrastructure. SDDC Manager is used to configure the
physical servers and switches as well as create and manage workload domains, monitor the status of the Cloud Foundation environment, and perform lifecycle management tasks such as patching and upgrades.

Hardware Management ServicesThe Hardware Management Services (HMS) provides the necessary functions required for discovering, bootstrapping, and monitoring the hardware components in each physical rack. The HMS is accessed through the VMware SDDC Manager using available APIs.

Storage PolicyCloud Foundation storage policies are set independently for each Workload Domain. Performance settings determine stripe width and thick vs. thin provisioning. Availability settings determine how many copies are stored and thus how many host
failures can be tolerated in a workload domain.
VMware Cloud Foundation leverages VMware vSAN to provide storage for workloads running in the private cloud. vSAN aggregates the local storage (both hybrid and all-flash configurations) from each host in the workload domain into storage pool that is shared across the cluster. Storage performance and availability characteristics are set when the workload domain is created. vSAN requires that each workload domain contains a minimum of three hosts, however four hosts
are recommended to facilitate host maintenance.

Physical NetworkThe VMware Cloud Foundation physical network design is based on a leaf-and-spine network architecture. Each rack contains a redundant pair of Top-of-Rack (ToR) switches. Each ToR switch is connected to a pair of high capacity spine switches
using 40GbE uplink ports. Servers are dual-connected to each ToR switching with separate 10GbE interfaces. The ToRs in the first rack provide access to the external data center network.

Logical NetworkVMware Cloud Foundation implements a virtual network overlay that runs on top of the physical leaf-and-spine network. Physical servers are logically grouped into vSphere clusters (represented as workload domains) where a Virtual Distributed
Switch is configured and port groups created. VMware NSX is also installed and a single transport zone is created. Logical switches and application virtual networks are manually created based on workload needs.
