Avaya S8700 Media Server
While all businesses require solid performance from their communications systems, there are
increasing levels of “availability” performance needed. To meet that need, the Avaya S8700
Media Server and its associated gateways accommodate three availability levels, as shown in
Table 46: S8700 configuration reliability levels
.
The Avaya S8700 Media Server also provides:
●
Automatic restoration of the most recently saved versions of translations following a power
outage. Translations are automatically shadowed onto the standby server across a
high-speed fiber optic link for memory duplication.
Note:
Note:
Translations can also be copied to S8300 Local Spare Processors (LSPs) in
G700 and G350 Media Gateways for automatic recovery in the case of network
partitioning or complete central site failure.
●
Scheduled backups of critical system information locally and/or at remote sites. In an
emergency, multiple copies of Communication Manager translations and server
configuration information are available. Saved information can be quickly restored.
●
Ability to recover from software failures through server interchanges. If the active server
needs to perform a non-call-preserving restart, the standby server can take over under a
slightly different operating system environment with nothing more than a call-preserving
warm restart. This ability is expected to enhance even traditional abilities, as it provides a
fail-safe mechanism to recover from obscure, intermittent “bugs.” (This is allowed by
processes duplicated on each server deliberately not running in lock-step
synchronization).
