Study Notes

Prerequisites for VCF Deployment on ESXi Hosts

Verify ESXi host hardware meets VMware vCenter Site requirements, including sufficient resources for the specific VCF workloads. Consult VMware documentation for detailed specifications.
Ensure sufficient storage capacity on ESXi datastores; accommodate VCF components and other applications.
Establish adequate network connectivity, including segmentation and proper network configuration, between ESXi hosts, other virtualization platforms, and cloud providers.
Confirm appropriate VMware tools are installed and updated with the latest patches and firmware for performance and security.
Establish a robust backup and recovery strategy for all ESXi hosts, VMs, and the VCF deployment as a whole, incorporating regular backups, archival storage, and disaster recovery mechanisms.
Confirm sufficient RAM (Random Access Memory) for vCenter Server. Required RAM size depends on host count, expected VCF components, and associated services.
Analyze disk space requirements for VCF installation and operation. Insufficient disk space causes installation/operational issues. Quantify storage capacity needed by VCF components.
Check storage capacity, types, and availability.

Network Configuration Requirements

Validate ESXi host network connectivity to vCenter Server and other necessary network components, including external resources.
Confirm necessary network adapters are available and functioning correctly.
Configure static IP addresses for critical network interfaces, using DNS for host names if necessary, to avoid DHCP issues.
Configure appropriate network profiles and security settings (e.g., firewall rules) to control traffic flows and isolate VCF components.

ESXi Host Security Configuration

Check ESXi host firewall settings to allow vCenter Server and other VCF component communication. Specific ports and services must be accessible.
Verify network access control security configurations and configure host firewalls for proper vCenter communication.
Enable SSH access to ESXi hosts for remote maintenance, noting security measures.
Configure robust password policies for ESXi hosts and vCenter Server, changing default passwords.
Implement security best practices (strong passwords, access controls, regular audits) for ESXi host management and security maintenance. Implement network segmentation, firewalls, and access controls. Review and update security policies and protocols regularly. Enforce multi-factor authentication for all users. Establish audit logs and monitoring systems.

ESXi Host Resource Management

Identify and quantify existing VM CPU and memory utilization on ESXi hosts. Assess potential resource contention and optimize after VCF deployment.
Analyze current ESXi host resource allocation to optimize other VM performance after VCF deployment. Consider the resource CPU and memory overhead of VCF components.
Ensure sufficient compute and memory resources in ESXi for vCenter Server functions.
Set up appropriate resource limits and reservations for VCF components and other workloads.

Datastore Considerations

Determine if existing storage meets VCF performance and capacity requirements. Verify datastores can accommodate the expected workload.
Test datastores for sufficient I/O performance matching vCenter requirements. Assess bandwidth needs.
Review datastore configurations to optimize them for expected VCF workloads. Plan sufficient storage capacity based on the number of VCF components.
Check existing VM datastores for alignment with VCF datastores; adjust as needed.

ESXi Host Management and Monitoring

Confirm management tools (remote access, monitoring dashboards, vCenter integrations) are in place or need introduction.
Establish processes for regular ESXi host monitoring and maintenance. Define logging, alerting, and troubleshooting procedures after deployment.

VCF Specific Post-Installation Configuration

Review VCF documentation for specific steps/configurations recommended for deployed VCF versions. Check for pre and post-installation checklists for VCF components. Use validated configuration guides and documentation. Pay attention to individual component deployments like the vCenter Server.

ESXi Host Configuration

Configure static IP addresses for ESXi hosts to avoid DHCP issues and maintain consistent network access, using DNS for host names if needed.
Install and configure the VMware vCenter Server Appliance or other appropriate management tools on a separate host. This aids infrastructure management.
Ensure vStorage APIs for Array Integration (VAAI) and VMware vSphere APIs for Storage Awareness (VASA) plugins are installed and enabled for improved storage performance and efficient data movement.
Configure shared storage policies for consistent storage access and performance, focusing on VMs within VCF.

ESXi Host Clustering

Configure ESXi hosts in a cluster for high availability and fault tolerance, enabling automatic VM migration. Ensure appropriate networking, security, and storage configurations, especially in multi-location clusters.
Deploy the cluster and VMs following VMware best practices, including maintaining adequate resource availability and distributing processing loads.
Set up appropriate resource limits and reservations, ensuring adequate network bandwidth, processing power, and storage capacity for VCF components and other workloads.

Security Considerations

Implement strong security measures, including network segmentation, firewalls, access controls, and multi-factor authentication policies.
Regularly review and update security policies and protocols.
Establish and maintain appropriate audit logs and monitoring systems for prompt detection and response to security events.

VCF Deployment Tools and Procedures

Ensure the appropriate deployment tools (vSphere Client or VCSA) are installed and configured for managing ESXi hosts.
Follow VMware's recommended procedures and best practices for VCF deployments, including the management of underlying infrastructure and specific component configurations.

Post-Deployment Verification

Validate all VCF components and VMs function as expected; test VM connectivity, network performance, and resource access.
Verify ESXi hosts for correct network and resource availability to ensure cluster and performance health.
Monitor the cluster regularly using VMware tools and dashboards, promptly addressing identified issues.
Confirm vCenter Server and ESXi hosts comply with current security guidelines and policies.
