To adjust the allocator capacity prior to ECE 3.5.0, you must reinstall ECE on the host with a new value assigned to the `--capacity` parameter. Starting with ECE 3.5.0, you can update the allocator capacity using the [allocator settings ECE API](https://www.elastic.co/docs/api/doc/cloud-enterprise/operation/operation-set-allocator-settings). After making this change, you must restart the allocator service for it to take effect.

```sh
curl -X PUT \
http(s)://<ece_admin_url:port>/api/v1/platform/infrastructure/allocators/<allocator_id>/settings \
-H “Authorization: ApiKey $ECE_API_KEY” \
-H “Authorization: ApiKey $ECE_API_KEY” \ <1>
-H 'Content-Type: application/json' \
-d '{"capacity":<Capacity_Value_in_MB>}'
```

For more information on how to use API keys for authentication, check the section [Access the API from the Command Line](cloud://reference/cloud-enterprise/ece-api-command-line.md).
After applying the change, log in to the allocator host you updated and restart the allocator service:

```sh
docker restart frc-allocators-allocator
```

Prior to ECE 3.5.0, regardless of the use of this API, the [CPU quota](#ece-alloc-cpu) used the memory specified at installation time.
