The following figure illustrates a logical architecture of Oracle database running on PowerFlex HCI system with VMware vSphere hypervisor integration with the DD Cloud Tier:
The DDVE is deployed on the PowerFlex HCI system running on-premises. The active tier metadata and data storage capacities are consumed from the PowerFlex storage. The Cloud Tier metadata storage capacity is consumed from the PowerFlex storage whereas data storage is consumed from the Amazon S3 object storage.
The Oracle database VMs running in the PowerFlex HCI system use the PowerFlex volumes for storing its datafiles, redo log members, and archive logs. The Oracle RMAN agent is installed on each database server. This Oracle RMAN agent includes the DD Boost libraries for communicating with the DD Boost server that runs on DDVE.
