System Platform is a generic virtual server software platform that provides a common set of features and services. This set of features and services allows preinstalled and configured virtual applications, called solution templates, to reside on a single physical server.
Base CentOS Linux system running the Xen Hypervisor (Dom0)
Web-based management console for installing and managing templates
Virtual machine for System Platform system utilities
Secure Access Link (SAL) to handle alarming and remote access
A consistent upgrade method for all patches and products in the solution template
Security that conforms to Avaya product security standards
A Web License Manager (WebLM) server to manage product licenses
A Network Time Protocol (NTP) clock synchronized to a customer-provided NTP server
System Platform includes CentOS as the base operating system, the Xen Hypervisor, and a virtual machine (CDOM) that is used to manage the platform. System Platform includes the following:
System Domain (Dom0): In addition to exporting virtualized instances of CPU, memory, network, and block devices, Xen displays a control interface to manage how these resources are shared between the running domains. Access to the control interface is restricted to a specially privileged virtual machine, known as domain 0 or System Domain.
Console Domain: Console domain is a virtual machine, which is a part of System Platform, and has many platform elements such as:
Common logging and alarming
Remote access
System Platform Web Console
Upgrades and patches
WatchDog
Licensing
User applications domain (udom): User applications domain is a virtual machine used to run with a specific type (or mode) of High Availability protection, according to Avaya Aura® solution template requirements.
All Messaging systems are installed on System Platform using a template. Avaya offers product-specific templates to install different products on System Platform. A template is a definition of a set of one or more applications to be installed on System Platform.
Messaging offers the following templates:
Msg_Standard.ovf. The Messaging template for the standard server.
Msg_4x146GB_HDD.ovf. The Messaging template for the high capacity storage server.
For more information on templates, see Implementing Avaya Aura® Messaging.
