Enhanced Platform Awareness (EPA) delivers carrier grade, low latency, data plane performance. VMware technologies including CPU pinning, Non-Uniform Memory Access (NUMA) placement, HugePages support, and SR-IOV support allow VNFs to maintain high network performance.
If you have configured VMware Integrated OpenStack as your VIM, you can define certain EPA attributes for increasing the performance capabilities of your VNFs. You can provide attribute values that are higher than the default value.
- Compute Performance Attributes:
- CPU Pinning
- NUMA Topology Awareness
- Memory Page Size (HugePage)
- Data Plane Performance Attributes:
You can enable the EPA capabilities on a VDU using the Network Function Descriptor on VMware Telco Cloud Automation. For more information, see Design a Virtual Network Function Descriptor.
