Compute Shapes
A shape is a template that determines the number of OCPUs, amount of memory, and number of VNICs that are allocated to a compute instance. You choose a shape when you create an instance.
Private Cloud Appliance supports two types of shapes:
- Standard shapes: Each shape has a fixed number of OCPUs and memory that are allocated to an instance when the instance is created.
- Flexible shape: You choose the number of OCPUs and amount of memory that are allocated to an instance.
Standard Shapes
Standard shapes are designed for general-purpose workloads and suitable for a wide range of applications and use cases. Standard shapes provide a balance of cores, memory, and network resources. All standard shapes use block storage for the boot device.
The following table lists the standard shapes:
| Shape | OCPUs | Memory (GB) | Maximum VNICs | Maximum Bandwidth (Gbps) |

Flexible Shape
A flexible shape lets you customize the number of OCPUs and the amount of memory for an instance. When you update an instance, you can change these properties of the flexible shape, and you can change from a fixed shape to a flexible shape. This flexibility lets you create instances that meet your workload requirements, while optimizing performance and using resources efficiently.
Private Cloud Appliance platform images support the flex shape.
The VM.PCAStandard.E5.Flex shape can be selected only for Private Cloud Appliance X10 systems.
