Configuration Overview - Oracle Netra Server X5-2 Installation Manual

Note:
The OCSBC relies on multiple queues on virtual NICs to scale session capacity.
Multiple queues enable the OCSBC to scale through multiple forwarding cores. This
configuration is platform dependent: physical NIC, Hypervisor, virtual NIC, and
vSwitch.
The user can learn how to pin CPUs via their hypervisor documentation.

Configuration Overview

Oracle Communications Session Border Controller Virtual Machine (VM) deployments require
configuration of the VM environment and, separately, configuration of the OCSBC itself. VM-
specific configuration on the OCSBC includes boot parameter configuration, enabling
functionality and performance tuning.
During VM installation, you can configure operational information within the system's boot
parameters, including:
• IP address
• Host name
Refer to the instructions on installing the OCSBC on each supported hypervisor to see how
and when you do this during installation. Refer to the ACLI Configuration Guide for instruction
on changing these settings after installation.
During VM installation, the OCSBC sets default functionality, assigning cores to signaling and
media forwarding. If you need DoS and/or transcoding functionality, configure the applicable
cores after installation and before performing service. See the ACLI Configuration Guide for
core configuration instructions.
Applicable performance tuning configuration after deployment includes:
• Media manager traffic/bandwidth utilization tuning
• Datapath-related CPU core allocation
See the ACLI Configuration Guide for instructions on VM tuning configuration.
Note:
For Xen-based hypervisors, the default boot mode uses DHCP to obtain an IP
address for the first management interface (wancom0) unless a static IP is
provisioned. Note that DHCP on wancom0 does not support lease expiry, so the
hypervisor must provide persistent IP address mapping. If persistent IP address
mapping is not provided, the user must manually restart the VM whenever the
wancom0 IP address changes due to a manual change or DHCP lease expiry.
Beyond installation, VM-related functional support, and VM-related tuning, you perform basic
OCSBC configuration procedures after installation, including:
• Setting Passwords
• Setup Product
