## Compute Resource Quota
You can limit the total sum of [compute resources](/docs/user-guide/compute-resources) and [storage resources](/docs/user-guide/persistent-volumes)
that can be requested in a given namespace.

| `memory` | Across all pods in a non-terminal state, the sum of memory requests cannot exceed this value. |
| `requests.cpu` | Across all pods in a non-terminal state, the sum of CPU requests cannot exceed this value. |
| `requests.memory` | Across all pods in a non-terminal state, the sum of memory requests cannot exceed this value. |
## Storage Resource Quota
You can limit the total sum of [storage resources](/docs/user-guide/persistent-volumes) that can be requested in a given namespace.
In addition, you can limit consumption of storage resources based on associated storage-class.
| Resource Name | Description |
| --------------------- | ----------------------------------------------------------- |
| `requests.storage` | Across all persistent volume claims, the sum of storage requests cannot exceed this value. |
| `persistentvolumeclaims` | The total number of [persistent volume claims](/docs/user-guide/persistent-volumes/#persistentvolumeclaims) that can exist in the namespace. |
| `<storage-class-name>.storageclass.storage.k8s.io/requests.storage` | Across all persistent volume claims associated with the storage-class-name, the sum of storage requests cannot exceed this value. |
| `<storage-class-name>.storageclass.storage.k8s.io/persistentvolumeclaims` | Across all persistent volume claims associated with the storage-class-name, the total number of [persistent volume claims](/docs/user-guide/persistent-volumes/#persistentvolumeclaims) that can exist in the namespace. |
For example, if an operator wants to quota storage with `gold` storage class separate from `bronze` storage class, the operator can
define a quota as follows:
* `gold.storageclass.storage.k8s.io/requests.storage: 500Gi`
* `bronze.storageclass.storage.k8s.io/requests.storage: 100Gi`
