Chapter 9. Scaling Multicloud Object Gateway performance by adding endpoints

The Multicloud Object Gateway performance may vary from one environment to another. In some cases, specific applications require faster performance which can be easily addressed by scaling S3 endpoints, which is a Technology Preview feature.

The Multicloud Object Gateway resource pool is a group of NooBaa daemon containers that provide two types of services enabled by default:

  • Storage service
  • S3 endpoint service

Scaling Multicloud Object Gateway performance by adding endpoints is a Technology Preview feature. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information, see Technology Preview Features Support Scope.

9.1. S3 endpoints in the Multicloud Object Gateway

The S3 endpoint is a service that every Multicloud Object Gateway provides by default that handles the heavy lifting data digestion in the Multicloud Object Gateway. The endpoint service handles the inline data chunking, deduplication, compression, and encryption, and it accepts data placement instructions from the Multicloud Object Gateway.

9.2. Scaling with storage nodes


  • A running OpenShift Container Storage cluster on OpenShift Container Platform with access to the Multicloud Object Gateway.

A storage node in the Multicloud Object Gateway is a NooBaa daemon container attached to one or more Persistent Volumes and used for local object service data storage. NooBaa daemons can be deployed on Kubernetes nodes. This can be done by creating a Kubernetes pool consisting of StatefulSet pods.


  1. In the Multicloud Object Gateway user interface, from the Overview page, click Add Storage Resources:

    MCG add storage resources button
  2. In the window, click Deploy Kubernetes Pool:

    MCG deploy kubernetes pool
  3. In the Create Pool step create the target pool for the future installed nodes.

    MCG deploy kubernetes pool create pool
  4. In the Configure step, configure the number of requested pods and the size of each PV. For each new pod, one PV is be created.

    MCG deploy kubernetes pool configure
  5. In the Review step, you can find the details of the new pool and select the deployment method you wish to use: local or external deployment. If local deployment is selected, the Kubernetes nodes will deploy within the cluster. If external deployment is selected, you will be provided with a YAML file to run externally.
  6. All nodes will be assigned to the pool you chose in the first step, and can be found under ResourcesStorage resourcesResource name:
