•
The machines which are intended to be used as primary 5620 SAM Server and 5620
SAM Database should be installed on the same LAN as one another with high quality
network connectivity.
•
The machines which are intended to be used as standby 5620 SAM Server and
standby 5620 SAM Database should be installed on the same LAN as one another
with high quality network connectivity.
•
The pair of workstations to be used as active 5620 SAM Server and 5620 SAM
Database should be connected to the pair of workstations to be used as standby 5620
SAM Server and 5620 SAM Database in a way that will prevent a single physical
failure from isolating the two workstation pairs from each other.
•
Workstations running the 5620 SAM Server and 5620 SAM Database software must
be configured to perform name service database lookups on the local workstation
before reverting to a name service database located on the network such as NIS,
NIS+, or DNS. A root user must inspect and modify the /etc/nsswitch.conf file to
ensure that
files
is the first entry specified for each database listed in the file.
Redundancy with distributed 5620 SAM Server and 5620 SAM Database and 5620 SAM Auxiliary
Collectors
In addition to the rules stated above for distributed 5620 SAM Server and 5620 SAM
Database, the following rules apply:
•
The operating systems installed on the 5620 SAM Auxiliary Collectors must be of the
same versions and patch levels as the 5620 SAM Server and 5620 SAM Database
workstations.
•
If collecting statistics using the 5620 SAM Auxiliary Database, the operating systems
installed on the 5620 SAM Auxiliary Database workstations must be of the same
versions and patch levels as the 5620 SAM Server and 5620 SAM Database
workstations.
•
5620 SAM Auxiliary Collectors are intended to be on the same high availability
network as the 5620 SAM Server and 5620 SAM Database. 5620 SAM Auxiliary
Statistics and Call Trace Collectors are intended to be geographically collocated with
the Active and Standby locations of the 5620 SAM Server and 5620 SAM Database.
The 5620 SAM Auxiliary Cflowd Collector typically resides in the managed network,
closer to the network elements.
•
If collecting statistics using the 5620 SAM Auxiliary Database, all workstations
hosting the 5620 SAM Server, SAM Database, 5620 SAM Auxiliary Statistics
Collector, and 5620 SAM Auxiliary Database must be geographically collocated with
a server to server latency of less than 1 ms.
•
Workstations running the 5620 SAM Auxiliary Collector software must be configured
to perform name service database lookups on the local workstation before reverting to
a name service database located on the network such as NIS, NIS+, or DNS. A root
user must inspect and modify the
/etc/nsswitch.conf
file to ensure that
files
is the first
entry specified for each database listed in the file.
