HP Management Base Installation and User's Guide (May 2006)

SDRR Sensor Data Record Repository. A required feature of a BMC, this is the material list for IPMI. It
starts with the list of sensors, their conversion and units, thresholds, and scanning information.
The SDRR also holds FRU lists, entity associations, and HP proprietary entries. The SDRR completely
describes the resources of an HP Integrity Server.
SEL System Event Log. A required feature of a BMC, this non-volatile log holds detected events that
are important or critical to system operation and may be very useful in post-mortem crash analysis.
It is an append-log, and when full will accept no new events. The hpseld program monitors the
capacity, maintains a disk copy, and clears the log when necessary.
SMIC Server Management Interface Chip. One of the System Interfaces used to connect a BMC to a
system CPU. This is a generic design best utilized when the BMC appears as a PCI device. SMIC
is not used on HP Integrity Servers.
SNMP Simple Network Management Protocol. Methods, data structures, and protocols defined in
RFC1155, 1156, and 1157 (earliest references) for data access and control of systems over a
network. SNMP development began in the early 1980s; today it is both a ubiquitous standard,
but also suffers from design hindsight in security and data complexity.
hpmgmtbase does not directly perform any SNMP operations but its libraries are used by products
that do, such as the Systems Insight Manager SNMP Agents for HP Integrity Servers.
WBEM Web-Based Enterprise Management. (pronounced (web-em). Methods, data structures, and
protocols defined by the DMTF (http://www.dmtf.org) for data access and control of systems
over a network. WBEM development began in the late 1990s, and is rich in object-oriented
techniques and secure access. Its acceptance is gaining at the time of writing (2006). While it
will probably never replace SNMP, it will supplant it in newer systems and designs.
hpmgmtbase does not directly perform any WBEM operations but its libraries are used by products
that do, such Systems Insight Manager WBEM Providers for HP Integrity Servers.
