Chapter 5. Developer previews
This section describes the developer preview features introduced in Red Hat OpenShift Data Foundation 4.11.
Developer preview feature is subject to Developer preview support limitations. Developer preview releases are not intended to be run in production environments. The clusters deployed with the developer preview features are considered to be development clusters and are not supported through the Red Hat Customer Portal case management system. If you need assistance with developer preview features, reach out to the ocs-devpreview@redhat.com mailing list and a member of the Red Hat Development Team will assist you as quickly as possible based on availability and work schedules.
5.1. Deletion of expired objects in the Multicloud Object Gateway lifecycle
Deletion of expired objects is a simplified way that enables handling of unused data. The unused data is handled either by moving it to a different location or by deleting it. This can be achieved by an Multicloud Object Gateway (MCG) lifecycle feature where you can use data tiering and data expiration features. Tiering enables tiering of data transparently to another backing storage. The entire data set would be available for the application regardless of its location. Data expiration is a part of Amazon Web Services (AWS) lifecycle management and sets an expiration date for automatic deletion. The minimal time resolution of the lifecycle expiration is one day.
For more information on data expiration, refer to the AWS lifecycle management.
5.2. Installing 3-node compact mode cluster using Red Hat Advanced Cluster Manager policy
With this release, OpenShift Data Foundation provides limited support to three node (3-node) compact mode clusters for all advanced storage features using the Red Hat Advanced Cluster Management (RHACM) policy.
This deployment support is limited to the bare metal platforms with local disks dedicated to OpenShift Data Foundation.
This provides the ability to deploy Rados Block Device (RBD)-only OpenShift Data Foundation clusters to conserve the resources where ReadWriteMany (RWX) and Object is not currently needed. This option enables a 3-node cluster that behaves like a full-fledged mobile data center that is simple to install.
For instructions about how to install a 3-node OpenShift Data Foundation compact cluster using RHACM policy, see the Red Hat Knowledgebase solutions for all clusters and IBM Power specific deployments.
