8 Analyzing Dell PS Series Storage with SAN Headquarters | TR1050
1.1 SAN HQ architecture
SAN HQ uses a client/server model which includes:
SAN HQ Server: This is the server which runs the Monitor (EQLxPerf) service and communicates to the PS Series groups.
SNMP requests are issued to collect configuration, status, and performance data. In addition, a syslog server may be
configured to log hardware alarms or performance alerts (syslog is typically the same IP as the SAN HQ server and is
configured in the PS Series Group Manager CLI or GUI).
SAN HQ Client: This provides a GUI for managing the SAN HQ environment and viewing data collected by one or more
SAN HQ servers. A SAN HQ Client accesses the log files maintained by the SAN HQ Server and formats the group data
into tables and graphs. You can run the SAN HQ Client on multiple computers.
SAN HQ stores the data in group log files. Computers running the SAN HQ client access the files and display the data in
the SAN HQ GUI.

Description
1
The computer running the Monitor Service issues a series of SNMP requests (polls) to each group for
configuration, status, and performance information. The Monitor Service also includes a syslog server
to which a PS Series group can log events.
2
When the first set of SNMP requests returns from a group, the Monitor Service stores this baseline
information in the log files for that group. The Monitor Service issues subsequent SNMP requests at
regular intervals of time (default: two minutes).
