5620 SAM also supports a distributed deployment, whereby the 5620 SAM Server and
the 5620 SAM Database software components are installed on two different workstations.
5620 SAM supports the distribution of statistics collection and the collection of call trace
information. A 5620 SAM Auxiliary can be configured for statistics collection, for call
trace collection, or for cflowd statistics collection. It can only be configured to perform a
single function. Statistics collection with a 5620 SAM Auxiliary uses either the 5620
SAM Database or the 5620 SAM Auxiliary Database for statistics record storage.
The 5620 SAM Auxiliary Database is deployed in a cluster of three servers and when
used with the 5620 SAM Auxiliary Statistics Collector, can be used to collect higher rates
of accounting, performance, and application assurance accounting statistics and to
increase retention of accounting, and performance statistics. The 5620 SAM Auxiliary
Database can only be used when statistics collection is performed with the 5620 SAM
Auxiliary Statistics Collector.
5620 SAM supports redundancy of the 5620 SAM Server, 5620 SAM Database, and 5620
SAM Auxiliary Collector workstations. The 5620 SAM Auxiliary Statistics Collector
supports 3+1 redundancy.
The 5620 SAM Auxiliary Database is deployed in a cluster of three separate instances and
can tolerate a single server failure with no data loss.
A 5620 SAM Auxiliary Statistics Collector must be installed on an independent
workstation and can only be configured in a 5620 SAM distributed deployment.
A 5620 SAM Auxiliary Call Trace Collector must be installed on an independent
workstation to collect the call trace information from WMM/vMM network elements. Up
to two active 5620 SAM Auxiliary Call Trace Collector workstations can be installed to
scale the collection of call trace information. Each active 5620 SAM Auxiliary Call Trace
Collector workstation can be assigned to a redundant workstation. Call trace information
is synchronized between the redundant pairs. The 5620 SAM Auxiliary Call Trace
Collector workstations can be configured in either a 5620 SAM distributed or collocated
deployment.
A 5620 SAM Auxiliary Cflowd Collector must be installed on an independent
workstation to collect cflowd flow records from the network. The 5620 SAM Auxiliary
Cflowd Collector does not use a traditional redundancy model. Instead, the 7750s can be
configured to send cflowd flows to multiple 5620 SAM Cflowd Auxiliaries. The 5620
SAM Auxiliary Cflowd Collector workstations can be configured in either a 5620 SAM
distributed or collocated deployment.
