Redundancy And Availability - Alcatel-Lucent Security Management Server (SMS) Release 9.4 Technical Overview

Alcatel-Lucent Security Management Server (SMS)

Redundancy and Availability

...................................................................................................................................................................................................................................
Overview
Basic redundancy is provided by two SMS servers that are installed in an active/active
fashion. These two active SMS servers maintain their configuration databases across
the network via real-time database replication. All inter-SMS communication is
secured. Starting with Release 9.0, for additional capacity and security in large-scale,
multi-site network designs, up to three Secondary SMSs can be connected to a Primary
SMS.
Since both the Primary and Secondary SMS servers are simultaneously active, each
Brick device can be configured from any SMS. Each Brick maintains a list of
SMSs/Compute Servers (CSs), and can be configured to prefer one SMS/CS over the
other servers (if it is available). Each Brick device sends log files to its currently-active
SMS/CS. A Brick device can be manually "rehomed" to the other server(s), if
available.
The SMS will automatically back up its internal database to a local disk once a day.
Additional backups can be scheduled at any time; backup files can be transferred to a
remote site for archival storage and disaster recovery. This single backup file contains
ALL policy, configuration, and security information for ALL configured devices and
policies.
