- SDDC Manager
- SDDC Manager is the VCF management component that automates inventory, workload domain creation, certificate and password management, and lifecycle operations across the VMware Cloud Foundation instance.
- Management workload domain
- The management workload domain is the first VCF workload domain created; it hosts SDDC Manager, vCenter Server, NSX Manager, and other shared management components for the environment.
- VI workload domain
- A VI workload domain is a VCF workload domain that hosts customer workloads and has its own vCenter Server, clusters, and compute, storage, and network configuration.
- vSAN
- vSAN is VMware's hyperconverged storage service that aggregates local ESXi host disks into a shared datastore used by VCF workload domains.
- NSX Manager cluster
- An NSX Manager cluster provides the management plane for NSX in VCF; it supports logical networking, security, and load balancing services used by workload domains.
- Network pool
- A VCF network pool defines IP address ranges and VLANs for traffic types such as management, vMotion, vSAN, and NSX VTEPs used during deployment and expansion.
- Cloud Builder
- Cloud Builder is the appliance used during initial VCF bring-up; it validates prerequisites and deploys the management workload domain from a deployment parameter workbook.
- External DNS and NTP
- VCF requires reliable external DNS with forward and reverse records and synchronized NTP sources; these services support component discovery, certificates, and authentication.
- Deployment parameter workbook
- The deployment parameter workbook is a spreadsheet input for Cloud Builder that defines hosts, networks, credentials, and sizing for the initial VCF management domain deployment.
- Host commissioning
- Host commissioning adds ESXi hosts to SDDC Manager's free pool after validating credentials, network connectivity, and compatibility; commissioned hosts can then join workload domains.
- Management domain deployment
- Management domain deployment is the initial VCF bring-up step that creates the first workload domain and its SDDC Manager, vCenter, NSX, and vSAN components.
- VTEP IP pool
- A VTEP IP pool supplies tunnel endpoint addresses for NSX overlay traffic; it must be sized and routed so hosts can establish Geneve tunnels across the network.
- Network validation
- Network validation checks VLANs, IP pools, MTU, DNS, NTP, and connectivity before VCF deployment; failures must be corrected because bring-up depends on these services.
- vSAN disk group
- A vSAN disk group combines cache and capacity devices on an ESXi host to provide vSAN storage; VCF deployment validates controller and disk compatibility.
- SDDC Manager inventory
- SDDC Manager inventory records hosts, workload domains, clusters, networks, credentials, and certificates; it is the source of truth for VCF lifecycle operations.
- Bring-up validation
- Bring-up validation confirms the management domain is healthy after deployment by checking SDDC Manager tasks, vCenter, NSX, vSAN health, and component connectivity.
- Password rotation
- Password rotation changes credentials for VCF components under SDDC Manager control; it must be coordinated because integrated services and scheduled tasks may use the same accounts.
- Certificate replacement
- Certificate replacement updates TLS certificates for VCF components; using SDDC Manager workflows helps avoid mismatched certificates and service outages across integrated components.
- SDDC Manager backup
- An SDDC Manager backup captures VCF inventory and configuration; vCenter and NSX require their own backups, so a complete recovery plan includes all management components.
- Workload domain expansion
- Workload domain expansion adds ESXi hosts to an existing cluster or creates a new cluster in a domain; it requires available network pool addresses and compatible hosts.
- vSAN health check
- vSAN health checks evaluate cluster components, disk groups, network performance, and data integrity; failed checks indicate storage issues that can affect VMs and VCF operations.
- NSX alarms
- NSX alarms report issues in logical networking, transport nodes, and security services; they help operators detect overlay connectivity or configuration problems in VCF.
- Support bundle
- A support bundle collects logs and diagnostic data from VCF components for VMware support; gather it before making changes that could overwrite evidence.
- Role-based access control
- Role-based access control in SDDC Manager assigns permissions to users or groups; integrating an identity source lets organizations manage VCF access with centralized accounts.
- Lifecycle Management
- Lifecycle Management in SDDC Manager orchestrates prechecks, bundle downloads, and upgrades for VCF components, helping keep management and workload domains at compatible versions.
- Upgrade prechecks
- Upgrade prechecks scan VCF for expired certificates, password mismatches, DNS or NTP failures, unsupported hardware, and capacity issues before an upgrade begins.
- Online depot
- The online depot is the VMware repository that SDDC Manager contacts to download upgrade bundles and metadata for VCF lifecycle operations.
- Offline depot
- An offline depot stores downloaded VCF upgrade bundles locally for environments without internet access; SDDC Manager uses it as the bundle source.
- Compatibility matrix
- The VCF compatibility matrix lists supported versions of SDDC Manager, vCenter, ESXi, vSAN, NSX, and other components; consult it before planning upgrades.
- Rolling upgrade
- A rolling upgrade updates components or hosts in stages while limiting downtime; VCF lifecycle workflows coordinate reboots and health checks during the process.
- SDDC Manager logs
- SDDC Manager logs record lifecycle tasks, API calls, and errors; they are a primary source for diagnosing failed deployments, upgrades, and configuration changes.
- Rollback limitation
- VCF upgrades may not support automatic rollback; backups, snapshots, and a documented recovery plan are needed before starting maintenance.
