Issue/Introduction
Customer says the CPU and Memory allocated to the VM components are too large to run on one NUMA node. It results in high CPU "READY". Customer wants help in reducing the CPUs and Memory allocatd to VM Component in VMware Cloud Foundation (VCF) 9.0
.
Environment
VMware Cloud Foundation (VCF) 9.0
Cause
The VMware Cloud Foundation (VCF) 9.0 product design comes with VM components with lot more resources allocated by default compared to its predeccesor (Aria Automation 8.x). In VCF 9.0 these excessive resources are allocated to accommodate cumulative requirements of the various management services.
Resolution
Currently there is no resource re-sizing, or modification supported in the VCF 9.0 version.
The Engineering is working on it actively to have the resizing of allocated resources support for VMs in the Automation components in the future release.
The Engineering do not have a date on the release of the product release at this time.
Additional Information
In VMware Cloud Foundation (VCF) 9.0, while some specific VM components can be resized, many management VMs for core VCF functions currently are not designed to be manually resized. Attempting to manually resize these VMs outside of a supported process is not recommended.
Manually resizing a core VCF management VM can lead to the following problems:
- Unsupported state: It can put the appliance in an unsupported state, which may be unrecoverable if a failure occurs.
- Upgrade failures: VCF lifecycle management operations, including upgrades, can fail if they detect that a component is not at its expected size.
- Loss of functionality: The resize operation could lead to a loss of functionality or data corruption, and restoring from a backup may be the only solution. s about the sizing on the two components at the time of deployment.
The following document talks about the sizing requirements on the two components at the time of deployment:
