The figure below shows the relationship between IOS-XR running on the ASR 9000 and StarOS running on the VSM.
Figure 3. IOS-XR and 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.
Each CPU socket is associated with a Crypto engine. PCI Ports are also assigned to accept traffic from the ASR 9000
line cards.
The table below shows how resources are assigned among the four CPUs on the VSM.
