According to the VMware Cloud Foundation 9.0.4 Documentation (p.5802–5804), administrators can configure resource limits for vSphere Namespaces, which define how much CPU, memory, and storage can be consumed.
The guide specifies under “Set Resource Limits to a vSphere Namespace”:
“As a vSphere administrator, you can set resource limits and container defaults on a vSphere Namespace. Options include CPU, Memory, and Storage. Container defaults set CPU limits, CPU requests, memory requests, and memory limits for containers within the Namespace.”
These limits provide governance and ensure that workloads deployed within a namespace do not exceed predefined consumption levels, maintaining cluster resource balance and preventing noisy-neighbor scenarios.
The document further clarifies that storage limits are applied per storage policy and CPU and memory limits define the total reserved compute capacity available to workloads and pods running in the namespace.
