VCF 9.1 Management Domain Model

A VCF fleet can include one or more VCF domains that are implemented according to a supported VCF Domain Model. Each VCF Domain Model has options, requirements, and recommendations.

• Management Domain Model

• Workload Domain Model

Management Domain Model

The management domain in a VCF fleet hosts the management components of the VCF Instance where it is deployed and the management components of the fleet.

Management Domain Model Attributes

The Management Domain Model has the following attributes.

Attribute	Details
Resource Allocation	VCF fleet management components. VCF Instance management components. NSX Edge nodes. Can also run business workloads.
Management Domain in the First VCF Instance	The management domain in the first VCF Instance contains the following management components: – VCF management services (fleet and instance level components) – VCF Operations – Cloud Proxy – VCF Operations for Networks – VCF Automation – ESX hosts – vCenter – NSX Manager – SDDC Manager
Management Domain in Additional VCF Instances	Management domains in additional VCF Instances contain the following instance-level management components: – VCF management services (instance-level components) – Cloud Proxy – ESX hosts – vCenter – NSX Manager – SDDC Manager

Management Domain Model Options

A Management Domain Model can apply options from the design areas listed below, depending on objectives.

Design Area	Options
vSphere Cluster Models	First cluster: – Single-Rack vSphere Cluster Model – Multi-Rack Layer 2 vSphere Cluster Model – Stretched vSphere Cluster Model (Day 2) Additional clusters: – All cluster models
VCF management services Models	Simple VCF Management Services Model High Availability VCF Management Services Model VCF Management Services in the First VCF Instance Model VCF Management Services in an Additional VCF Instance Model

Workload Domain Model

As you expand your VCF fleet, you add workload domains to a VCF Instance. Each workload domain is assigned a vCenter and NSX Manager.

Workload Domain Model Attributes

A Workload Domain Model has the following attributes

Attribute	Details
Resource Allocation	NSX Edge nodes. Business workloads.
vCenter Single Sign-On Domain	Dedicated

Workload Domain Model Options

A Workload Domain Model can apply options from the design areas that are listed below, depending on the objectives

Design Area	Options
vSphere Cluster Models	Single-Rack vSphere Cluster Model Multi-Rack Layer 2 vSphere Cluster Model Multi-Rack Layer 3 vSphere Cluster Model Stretched vSphere Cluster Model
NSX Manager Models	Simple NSX Manager Model High Availability NSX Manager Model
NSX Consumption Models	Dedicated NSX instance. Shared NSX instance with another workload domain, including the management domain
Workload Network Type	IPv4 IPv6
