Chapter 1. Overview of deploying in external mode
Chapter 1. Overview of deploying in external mode Red Hat OpenShift Data Foundation can make services from an external Red Hat Ceph Storage cluster available for consumption through OpenShift Container Platform clusters running on any platform. See Planning your deployment for more information. For instructions regarding how to install a RHCS cluster, see the installation guide . Follow these steps to deploy OpenShift Data Foundation in external mode: Deploy OpenShift Data Foundation using Red Hat Ceph Storage . Deploy OpenShift Data Foundation using IBM FlashSystem . 1.1. Disaster recovery requirements Disaster Recovery features supported by Red Hat OpenShift Data Foundation require all of the following prerequisites to successfully implement a disaster recovery solution: A valid Red Hat OpenShift Data Foundation Advanced subscription A valid Red Hat Advanced Cluster Management for Kubernetes subscription For more information, see the knowledgebase article on OpenShift Data Foundation subscriptions . For detailed disaster recovery solution requirements, see Configuring OpenShift Data Foundation Disaster Recovery for OpenShift Workloads guide, and Requirements and recommendations section of the Install guide in Red Hat Advanced Cluster Management for Kubernetes documentation. 1.2.
