The system administrator can deploy Avaya Contact Center – Extended Capacity in the Simplex, local High Availability (local HA), or geo-redundant High Availability (geo-redundant HA) without Layer 2 networking environments.

Simplex deployment

In the Simplex deployment, the contact center operates in one data center that contains one Configuration Server and one Routing Core Server. The contact center does not provide server High Availability and cannot operate in case of server failure or maintenance procedures. Avaya recommends that you use Simplex deployment only in a lab environment.

The following diagram provides an overview of the Simplex deployment architecture:

Local HA deployment

In the local HA deployment, the contact center operates in one data center that contains one Configuration Server and two Routing Core Servers.

The following diagram provides an overview of the local HA deployment architecture:

Geo-redundant HA deployment without Layer 2 networking

The contact center operates in two geographically separate data centers. Each data center contains two Configuration Server and two Routing Core Server instances.

Without Layer 2 networking, each data center contains an independent set of contact center servers and supports disaster recovery. In case of the primary data center failure, the Avaya Contact Center – Extended Capacity recovers contact center operations in the secondary data center and does not preserve active calls and agent states. The contact center supports high availability for Configuration Server and Routing Core Server instances within each data center.
