For the most part, capabilities of the main server and the survivable core server are the same if both are of the same platform type. There are some important differences between the main server and the survivable core server that should be taken into consideration when planning and designing a survivable core server configuration:
License file: The license file of the main server must have ESS Administration enabled and Enterprise Survivable Server disabled.
Translations: You can change translations on a survivable core server but you cannot save them. A file sync from the main server to the survivable core server will over-write translations performed on the survivable core server.
Administrative value: The value of the main server is always the highest ranking value on an Media Gateway’s priority list. The value for the main server cannot be administered. However, the value of each survivable core server is administrable. For more information on administration, see Survivable core server administration.
Survivable core server capacity: When used as a survivable core server, the survivable server match the capacity of the main server that is used as a main server.
For more information about system capacities, see Avaya Aura® Communication Manager System Capacities Table .
Processor Ethernet: Processor Ethernet can be used on both the simplex main server and the simplex survivable core server. On the simplex main server the Processor Ethernet interface can be used for adjunct connectivity, H.323 endpoint registration, and gateway registration. The Processor Ethernet interface can be used for support of H.323 devices and gateways and adjunct connectivity if you administer relevant fields on the Survivable Processor screen.
For more information on how the Processor Ethernet functionality works on main servers and survivable core servers, see Processor Ethernet functionality.
