White Paper - Remote Management SNMP SubAgent

7.2 Modify Sensor Thresholds
Some of the sensors thresholds can be modified by the management application. These sensors
thresholds are written to the SDR (Sensor Data Record) repository for each device accessible through
the BMC. The voltage, temperature and fan sensors have modifiable thresholds. The SNMP SET
command is used to modify the sensor thresholds. The support for the SET command for the SNMP
sub-agent is configurable, for example, whether a user can change a sensor’s threshold value or not
etc.
7.3 Memory and Processor Information
Information about all the memory arrays and also every memory device on each array is available. The
status, location, max capacity, number of memory devices, mirroring status, sparing status, and RAID
status are exposed to the SNMP application. For each memory device, its status, total width, data
width, size, speed, bank location, and memory type along with other information is made available
from SMBIOS table.
7.4 Overall System Health Status
The overall system health status is based on the status of sensors supported by the platform. The
health of each sensor is monitored based on its upper and lower thresholds limits. If all the devices
are in healthy state, the overall system health would be shown as “OK”. The details of information in
the trap message are given in section 7.1.
8. SNMP Application – a client-side perspective
Organizations always seek to improve their network availability and performance, increase staff
efficiency, and reduce operating expenses. The benefits of Network Management Software (NMS) are
enhanced by integration with other device management software. This enables optimized utilization
of resources including people, processes, and technology. A server with Intel® SNMP Subagent can be
managed by any client software through SNMP interface. This section illustrates few NMS products
that can be used to manage Intel Server Hardware.
8.1 HP Software & Solutions*
The HP Software & Solutions is a new name of HP Open View [8]. HP Network Node Manager (NNM),
a part of Open View suite, has integration capability of different NMS. The MIB browser, as shown in
Exhibit 8a, is also supplied as part of NNM. After loading the MIB, user can perform the SNMP Get/Set
operations on an Intel® SNMP Subagent.
