The figure below shows the relationship between IOS-XR running on the ASR 9000 and StarOS running on
the VSM.

The 10GE interfaces on the SecGW virtual machines are visible as 10GbE interfaces on the ASR 9000. The
ASR 9000 line card forwards IP traffic to VSM 10GbE ports.

VSM Resource Mapping to VPC-VSM VMs
There are four CPU sockets on the VSM. Each CPU supports multiple cores. A VPC-VSM instance uses
multiple virtual CPUs (vCPUs) consisting of available cores for its virtual machine.
