+# Base Database Cloud@Customer Infrastructure
+
+Oracle Data Infrastructure Cloud@Customer provides Base Database VM Clusters and Application VMs on Oracle-owned and managed infrastructure located in the customer’s data center.
+
+Oracle Data Infrastructure Cloud@Customer hosts one or more VM Clusters that run Oracle AI Databases. The same Data Infrastructure also hosts Application VMs for customer-managed application workloads.

+## Infrastructure options
+
+Oracle Base Database Service on Cloud@Customer X11 is shipping with the follwoing infrastructure:
+
+- 2x x86 Oracle X11 Database Servers (E6-2L)
+- 2x AMD® EPYC 9J15 32-core 2.9 GHz (up to 4.4 GHz) processors (per server node)
+- 60 usable cores (per server node)
+- 660 GB usable memory (per server node)
+- One external storage shelf with 6, 12, 18 or 24 7.68 TB 3.5 inch SSD to provide 11.6 - 47.2 TB of usable capacity
+- 2x 10 Gbps copper or 10/25 Gbps fibre for Client network connections (per server node)
+- optional 2x 10 Gbps copper or 10/25 Gbps fibre for Backup network connections (per server node)
+- 2x 10 Gbps copper for CPS network connections (per server node)
+
+> [!NOTE]
+> Client and backup media type must match – Fiber/Fiber or Copper/Copper
+
+## Supported Editions and Versions
+The following Oracle Grid Infrastructure versions and Oracle AI Database editions and versions are supported.
+
+### The following Oracle Grid Infrastructure versions are supported:
+
+- Oracle Grid Infrastructure 26ai
+
+### The following Oracle AI Database editions are supported:
+
+- Standard Edition
+- Enterprise Edition
+- Enterprise Edition High Performance
+- Enterprise Edition Extreme Performance
+
+> [!NOTE]
+> Oracle AI Database Enterprise Edition Extreme Performance is required for multi-node Oracle Real Application Clusters (Oracle RAC) systems.
+
+### The following Oracle AI Database versions are supported:
+
+- Oracle AI Database 26ai
+- Oracle Database 19c
+
+## Resource Allocation
+
+The BaseDB-C@C X11 supports the creation of a maximum of 8 Virtual Machines (VMs) on one node and a total of maximum of 12 VM Clusters across the infrastructure.
+
+The supported VM Clusters:
+
+- Two node Database VM Cluster
+- One node Database VM Cluster
+- One node Application VM Cluster
+
+> [!NOTE]
+> The Database VM Clusters are using ECPU (Elastic Compute Units) metric for measuring consumption, while the Application Cluster is using OCPU (Oracle Compute Units)
+
+- An OCPU is the equivalent of a physical core of a processor (CPU). A billing based on OCPUs binds the price to the make, model or clock speed of the underlying CPU. But CPU capacities increase with every new release, rendering a correct price to performance metric relation too complex.
+- An ECPU is based on the number of cores that are elastically allocated per hour to the VM Cluster from a pool of Exadata database servers and storage servers. This metric is independent of the underlying physical hardware, making it the basis for billing in the Cloud for the long-term future.
