Each instance of Oracle Exadata Database Service on Dedicated Infrastructure contains multiple database servers and Exadata storage servers that are connected by high-speed, low-latency network fabric. The Exadata database and storage server racks reside in an Oracle Cloud Infrastructure (OCI) region.

With elastic expansion in Exadata X8M and later, the starting configuration is similar to a quarter rack (2 database and 3 storage servers), and you can expand up to 32 database servers and 64 storage servers to support workloads of different sizes.

Each Oracle Exadata database server contains one or more virtual machine (VM) guests. With support for multiple virtual machine clusters (MultiVM), you can support up to 8 VMs per database server and host a total of 8 VM clusters per Exadata Database system, and you can specify how the overall system resources are allocated to the VM clusters. VM cluster node subsetting enables you to allocate a subset of database servers to new and existing VM clusters to enable maximum flexibility in the allocation of compute (CPU, memory, and local storage) resources.

The client and backup networks provide access to your VM clusters. Oracle manages the infrastructure through the management network, which connects the database and storage server hardware.
