Study Notes
Scaling a Cluster within VMware Cloud Foundation 5.2
- Scaling a vCenter Server cluster involves adjusting cluster resources (compute and storage) to meet evolving demands. Adding or removing ESXi hosts (horizontal scaling) or vSAN storage capacity (vertical scaling) alters capacity.
- Horizontal scaling changes the number of ESXi hosts, impacting overall compute capacity. Vertical scaling alters vSAN storage for applications.
- Careful planning, considering current and projected resource utilization (CPU, memory, storage), is vital to avoid performance issues and service disruptions.
-
Pre-Scaling Considerations:
- Validate sufficient storage capacity for the anticipated workload.
- Assess existing capacity against needs.
- Verify dependencies with other VCF components (e.g., NSX, vCenter).
- Confirm compliance and security requirements.
- Identify potential bottlenecks in the existing cluster.
-
Horizontal Scaling (Adding Hosts):
- Ensure enough network capacity.
- Verify compatibility of ESXi hosts (hardware and software).
- Validate planned host infrastructure.
- Utilize vSphere Client or vCenter Server to add hosts to the cluster. Proper host configuration is critical.
- Validate added hosts, confirming network connections and operational status in vSphere.
-
Vertical Scaling (Adding Storage):
- Confirm storage compatibility with vSAN configuration.
- Evaluate vSAN storage capacity requirements.
- Plan carefully, reviewing available resources to support the workload.
- Configure datastores via vSphere Client or vCenter Server.
- Monitor and validate vertical scaling operations closely.
-
Post-Scaling Validation:
- Verify successful scaling, monitoring resource allocation and performance.
- Adjust virtual machine configurations as needed.
- Assess and adjust performance metrics for optimized resource usage (after horizontal scaling, more common).
- Review logs for errors.
- Conduct regular performance analysis (CPU utilization, I/O throughput, network traffic).
-
VCF 5.2 Specific Considerations:
- Ensure compatibility with the VCF 5.2 architecture.
- Utilize automation tools (vCenter Orchestrator) to improve efficiency and reduce errors.
- Adhere to VCF 5.2 best practices.
- Address any specific vSAN requirements.
-
Troubleshooting Scaling Issues:
- Utilize performance monitoring and logging for rapid issue identification.
- Employ vCenter Server and vSphere Client for troubleshooting.
- Optimize configurations to eliminate bottlenecks.
- Check for conflicts with other platform components.
- Verify correct completion of all scaling steps.
-
Security Considerations:
- Implement robust security measures after scaling.
- Protect against unauthorized access and malicious attacks.
- Adhere to strict data handling and security protocols.
- Validate security audits cover the modified cluster.
