Study Notes

Prerequisites

  • Ensure the target vCenter Server, linked to the vSphere domain within vSphere Cloud Foundation, has the required compute and storage resources.
  • Confirm the vCenter Server is correctly configured and integrated into the vSphere Cloud Foundation domain.
  • Verify sufficient network connectivity between the target vCenter Server and the vSphere Cloud Foundation components.
  • Confirm the necessary VMware vSphere licenses are installed and activated on the target vCenter.
  • Verify vCenter and vSAN connectivity from the cluster being added.

Adding a Cluster

  • Access the vSphere Cloud Foundation Management UI (vCenter Server).
  • Navigate to the vSphere domain interface.
  • Select the vCenter Server hosting the intended cluster.
  • Identify the cluster to be added.
  • Choose the "Add Cluster" option in the vSphere Cloud Foundation interface.
  • Provide the vCenter Server details (host and/or cluster metadata) where the cluster resides.
  • Ensure the target cluster's network configuration is properly set up, potentially using vSphere Standard or Advanced Networking.

Cluster Configuration

  • Review the cluster configuration, including vSAN settings (if applicable).
  • Verify the cluster's hardware (CPU, memory, networking) and storage allocation.
  • Confirm the chosen storage policy aligns with the vSphere domain's storage requirements.

Verification

  • Post-addition, confirm the cluster is part of the vSphere Cloud Foundation domain within the vCenter console.
  • Monitor cluster status during integration for any issues.
  • Check cluster health and performance metrics after integration into the vSphere Cloud Foundation domain.
  • Review vCenter logs and vSphere Cloud Foundation monitoring tools for errors.

Post-Addition Procedures

  • Check resource allocation in the new cluster verifying appropriate usage to avoid overutilization.
  • Establish VM and application configurations aligning with vSphere domain policies and best practices.
  • Ensure proper monitoring and alerting for the added cluster to maintain performance consistency.
  • Consult vSphere Cloud Foundation documentation for cluster configuration adjustments after addition.
  • Verify resource limits within the vCenter Server and the cluster's capacity (CPU, memory).

Potential Issues

  • Problems with vCenter credentials or network configurations.
  • Insufficient resources on the target vCenter Server.
  • Incompatible vSAN configurations.
  • Mismatched vSphere storage policies.
  • Connectivity issues.
  • License mismatches.

Considerations for vSAN

  • Ensure the vSAN configuration for the new cluster matches the vSphere Cloud Foundation vSAN policy.
  • Verify the vSAN health metrics after integration to confirm proper vSAN resource allocation.

Considerations for Distributed Resource Management

  • Ensure the cluster is part of DRS or other resource management mechanisms (as required).

Prerequisites

  • Confirm the target cluster has the necessary infrastructure (compute, storage, networking) provisioned and configured.
  • Verify vCenter Server and NSX-T Data Center accessibility to the vCloud Director instance.
  • Validate authentication and permissions for the vCloud Director user executing the operation.
  • Ensure the vCloud Director instance runs the latest supported VMware Cloud Foundation version.

Adding a Cluster

  • Access the vCloud Director console and identify the existing vCloud Foundation domain.
  • Locate the vCenter Server (associated with the target domain).
  • Access the vCenter Server (using vSphere Client or vCenter Operations Manager).
  • Confirm the target cluster in the vCenter Inventory exists.
  • In vCloud Director, select the desired domain.
  • Proceed to Clusters in the Navigator.
  • Use the "Add Cluster" option.
  • Provide the required cluster information (name, vCenter details).
  • Specify the cluster location within the vCloud Foundation domain.
    • Account for resource allocation and design constraints before adding.
  • Review the settings.
  • Validate configurations and confirm compatibility with the existing infrastructure.
  • Accept the validation results.
  • Initiate cluster addition through vCloud Director.
  • The addition process should automatically integrate the cluster into the vCloud Foundation domain.

Post-Addition Configuration

  • Review newly added cluster details in vCloud Director to verify integration.
  • Confirm the cluster displays as part of the vCloud Foundation infrastructure.
  • Monitor logs and performance metrics to assess cluster health.
  • Configure needed cluster-specific policies/settings (resource quotas, security, network rules).
  • Check the functioning of the newly added cluster within vCenter after addition.

Considerations

  • Network connectivity is vital for communication between the cluster and other vCloud Foundation domain components.
  • Cluster licensing must be compatible with the existing vCloud Director components.
  • Compatibility between vCenter, NSX-T, and the cluster elements must be confirmed before deployment to prevent issues.
  • Ensure accessibility and management of the added cluster within the vCloud Foundation structure.
  • Address any resource conflicts (storage or compute oversubscription).
  • Define monitoring and maintenance procedures for the new cluster.

Typical Issues and Troubleshooting

  • If addition fails or cluster doesn't sync, consult vCloud Director and vCenter Server logs for errors.
  • Check network connectivity between the added cluster and vCloud Foundation components.
  • Investigate conflicting configurations or software version incompatibility.
  • Monitor cluster performance after addition to resolve scaling/stability issues.
  • Verify necessary resources for the cluster (hardware/software).
  • Ensure cluster networking compatibility with the vCloud Foundation networking configuration.
  • Double-check vCenter Server and vCloud Director authentication for proper communication.
