    Study Notes

    Deploying Stretched Clusters in vCloud Foundation 5.2

    • Prerequisites: A vCloud Foundation 5.2 instance with appropriate networking and storage configurations is needed. A secondary site with supporting infrastructure is required. Geographic separation of sites is crucial for disaster recovery.

    • Planning the Stretched Cluster: Identify the primary and secondary data centers. Determine network connectivity (VLANs, IPs), ensuring secure site-to-site connectivity. Select the secondary site's storage solution, planning capacity for both sites and maintaining consistent storage access for VMs.

    • Networking Configuration: Establish dedicated network segments for stretched cluster communication. Configure aligned and accessible VLANs in both primary and secondary sites. Connect vCenter Server instances between sites; secure network configurations to restrict access to resources are essential.

    • Storage Configuration: Identify the secondary site's storage solution, aligning with or creating a compatible structure with the primary site's storage. This involves storage replication or shared storage setup; consistent storage access is required.

    • vCenter Server Deployment: Deploy the secondary vCenter Server instance following vCenter best practices and check hardware/software requirements. Ensure vCenter servers are properly configured for their respective roles.

    • Storage Replication Setup: Connect primary site storage to the secondary site using replication protocols or shared storage. This is crucial for consistent storage access.

    • VMware Site Recovery Manager Setup: Configure disaster recovery with VMware Site Recovery Manager, designating replicable VMs.

    • Deployment of vSphere Clusters: Install and configure vCenter Server and ESXi hosts in the secondary site for each vSphere cluster, ensuring appropriate licensing.

    • Connection between vCenter Servers: Establish a connection between vCenter Server instances using vCenter Single Sign-On (SSO) for cross-site management.

    • VM Migration or Replication: Migrate or replicate VMs between clusters using Site Recovery Manager, either manually or automatically; a detailed replication strategy is needed.

    • Configure HA and DRS: Apply High Availability (HA) and Distributed Resource Scheduling (DRS) policies to both stretched clusters, as with single-site clusters, for redundancy and resource allocation.

    • Verify the Stretched Cluster: Test performance and connectivity between both vSphere environments using simulated scenarios; ensure VMs run in the secondary site. Realistic testing is essential.

    • Monitoring and Maintenance: Implement comprehensive monitoring and maintenance (logging, alerts, scheduled checks) for both sites. Regular maintenance is vital.

    • Disaster Recovery Testing: Validate the recovery process, ensuring the stretched cluster functions as expected during a disaster, following existing disaster recovery procedures. Implement practices for successful disaster recovery workflows. Thorough testing and validation are important.

    • vCloud Director Configuration: Register the vCloud Director instances across sites in vCloud Director.

    • Network Infrastructure Setup: Set up the proper network configuration and ensure interoperability across the separated locations.

    • Storage Integration: Design and configure a consistent and reliable storage strategy, emphasizing replication capabilities and storage protocols.

    • NSX Manager Configuration: Deploy an NSX Manager component in each site to facilitate networking requirements and network virtualization.

    • vCloud Director Integration and Configuration: Integrate and configure vCloud Director instances from each of the separated locations in the vCloud Foundation environment.

    • Resource Provisioning and Deployment: Establish a detailed VM replication strategy; allocate resources for each site for performance.

    • Automated Failover Mechanisms: Configure automated failover mechanisms for VMs in case of site failure.

    • Testing and Validation: Conduct thorough testing procedures and validation of failover functionality.

    • Post-Deployment Steps: Establish monitoring to maintain optimal functionality, verify security policies, conduct regular testing, and maintain components and underlying infrastructure.

    • Security Considerations: Implement secure network configurations to restrict access to resources and ensure data security across the sites.

    • Essential Considerations and Best Practices: Adhere to VMware best practices, optimize network traffic, apply security patches, plan for capacity, and ensure sufficient capacity across sites for expected demand.
