Virtual Machine Platform Resources

A Virtual Network Function (VNF) requires the CPU core, memory, disk size, and network interfaces specified for operation. Deployment details, such as the use of distributed DoS protection, dictate resource utilization beyond the defaults.

Default VNF Resources

VM resource configuration defaults to the following:

• 4 CPU Cores
• 8 GB RAM
• 20 GB hard disk (pre-formatted)
• 8 interfaces as follows:
  • 1 for management (wancom0 )
  • 2 for HA (wancom1 and 2)
  • 1 spare
  • 4 for media

Interface Host Mode

The OCSBC S-Cz8.2.0 VNF supports interface architectures using Hardware Virtualization Mode - Paravirtualized (HVM-PV):

• ESXi - No manual configuration required.
• KVM - HVM mode is enabled by default. Specifying PV as the interface type results in HVM plus PV.
• XEN (OVM) - You must configure HVM+PV mode.

Note:

When deploying the OCSBC over VMware and using PV interface mode, the number of forwarding cores you may configure is limited to 2, 4, or 8 cores.

CPU Core Resources

The OCSBC S-Cz8.2.0 VNF requires an Intel Core7 processor or higher, or a fully emulated equivalent including 64-bit SSSE3 and SSE4.2 support .

If the hypervisor uses CPU emulation (qemu etc), Oracle recommends that you set the deployment to pass the full set of host CPU features to the VM.
