System Architecture

Last Updated : Jan 09, 2026 |

Avaya SBC deployment on Avaya Solutions Platform 130 Appliance R6.0.x (KVM on RHEL 8.10) uses a virtual architecture model. In this model, the Element Management Server (EMS) and SBC instances run as separate Virtual Machines (VMs) on KVM hosts.

Dell R660xs platform powers each appliance host, configured for high-performance, low-latency networking and predictable SBC behavior. Depending on the deployment size and redundancy requirements, you can manage one or more SBC High-Availability (HA) pairs with either a single EMS or an EMS HA pair.

The following are the functions of the virtual components:

  • EMS VM: Manages, configures, and monitors SBC instances from a centralized interface.

  • SBC VM: Provides signaling and media processing for SIP sessions, secured through encryption and topology hiding.

  • Each VM uses dedicated vCPUs, memory reservations, and network bridges that map directly to physical Network Interface Cards (NICs) on the host.
