Redundancy and 5620 SAM Auxiliary workstations
In customer networks where the statistics collection requirements exceed the scalability
capabilities of a 5620 SAM Server, the 5620 SAM Auxiliary Statistics Collector can be
used. As with other high availability components, 5620 SAM Auxiliary Statistics
Collector can be configured to be redundant. When collecting statistics using the 5620
SAM Database, each 5620 SAM Server can be configured to have one preferred and one
reserved 5620 SAM Auxiliary Statistics Collector. When collecting statistics using the
5620 SAM Auxiliary Database or logToFile only, each 5620 SAM Server can be
configured with up to three preferred and one reserved 5620 SAM Auxiliary Statistics
Collector. When collecting statistics using the 5620 SAM Auxiliary Database, latency
between all 5620 SAM workstations, including redundant servers (except for Clients and
Client Delegates), must be less than one millisecond.
When Call Trace information is being collected from WMM network elements in
customer networks, a 5620 SAM Auxiliary Call Trace Collector must be used. The 5620
SAM Auxiliary Call Trace Collector can be installed in a redundant pair. Up to two 5620
SAM Auxiliary Call Trace Collector redundant pairs can be installed.
