Following up on my previous post about Configuration Drift I would like take a fresh look at additional functionality.
Maintaining configuration compliance across a constantly evolving private cloud can be complex and time-consuming. I am excited about a major improvements to vSphere Configuration Profiles (VCP) that expand its reach and intelligence, allowing customers to achieve and maintain their desired state configuration with unprecedented automation and integration.These enhancements turn VCP into a central mechanism for unifying core infrastructure management, including new host onboarding, advanced storage, and performance optimization.
Automatic and Intelligent RemediationThe improved VCP significantly simplifies cluster scaling and lifecycle management through intelligent automation.
- Automatic Remediation: When new hosts are added to vSphere Configuration Profile-enabled clusters, the desired state configuration is automatically applied and remediated for the incoming host. This dramatically reduces manual, error-prone steps during scale-out events.
- Host-Specific Attributes: The system automatically extracts host-specific attributes—such as unique IP addresses—from the incoming host and adds them to the host-specific section of the cluster profile, ensuring configuration consistency without requiring manual updates.
This automated drift detection and remediation capability is also visible in VCF Operations, which offers a per-cluster remediation button to fix drift and helps maintain alignment with required compliance standards
VCP for Memory Tiering: vSphere Configuration Profiles are now used to configure memory tiering for hosts within the cluster. This process allows the system to claim NVMe devices for memory tiering, with the option to claim an additional NVMe device as a mirror device for software mirroring to ensure resilience.
Deeper vSAN Integration and Storage Efficiency
In this blog post we wil deep dive into the vSAN Policy Definition and how to assign this policy to a configuration drift.
So let’s start:
vSphere Configuration Profiles now integrate seamlessly with vSAN to manage complex storage configurations and ensure no operational impacts during remediation.
- vSAN Policy Compliance: VCF ensures that configuration and remediation changes do not negatively impact vSAN. It honors existing vSAN maintenance mode policies and object accessibility policies when remediating vSAN clusters.
- Advanced Configuration Management: Advanced vSAN configuration can now be applied cluster-wide. For customers utilizing the vSAN Express Storage Architecture (ESA), VCF 9.1 introduces a key feature: vSAN Global Deduplication and Compression. Additionally, RAID 5/6 is the recommended policy for ESA going forward, offering comparable performance to RAID 1 due to the log-structured file system, with Auto-RAID automatically selecting the appropriate RAID level based on the host count.
- Encryption and Deduplication: For security, vSAN global deduplication is applied before vSAN encryption.
Create a Sub-Policy and define you desired stare.
The configuration framework supports a wide range of parameters, including detailed Policy Definitions, Alert settings, and custom Supermetric
With the Sub-Policy now defined, we can proceed to create a Configuration Drift Template and integrate the settings from the policy above.
Final Thoughts
This new release delivers significant enhancements to vSphere Configuration Profiles (VCP)—the key takeaway that will fundamentally change cloud stability and efficiency.
