Chapter 5. Developer previews

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.

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 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.
