network control and monitoring protocol, is part of the original TCP/IP protocol
suite. SNMP provides the format in which vital information about different
network devices, such as network servers or routers, can be sent to a management
application.
SNMP trap
A notification (event) generated by the RAC or ESM that contains information
about state changes on the managed system or about potential hardware problems.
SODIMM
Acronym for small outline-DIMM. A DIMM module with a thinner profile due
to the use of TSOP chip packages. SODIMMs are commonly used in
portable computers.
SOIC
Abbreviation for Small Outline IC, a small-dimension, plastic, rectangular,
surface mount chip package that uses gull-wing pins extending outward.
SOJ
Abbreviation for small outline package J-lead, a small-dimension, plastic,
rectangular surface mount chip package with j-shaped pins on its two long sides.
SOL
Abbreviation for Serial Over LAN. SOL enables suitably designed servers to
transparently redirect the serial character stream of a baseboard UART to/from a
remote client over a shared LAN. The architecture requires software running on
the managed system's BMC and client software running on a management station
and/or a central network proxy.
SRAM
Abbreviation for static random-access memory. Because SRAM chips do not require
continual refreshing, they are substantially faster than DRAM chips.
SSH
Abbreviation for Secure Shell.
SSH is a program that may be used to log into another system over a network, to
execute commands in a remote system, and to move files from one system to
another. It provides strong authentication and secure communication over
insecure channels.
