network management
station (NMS) A powerful workstation with one or more network management applications
installed. The NMS is used to remotely manage a network.
network mask A number used by software to separate the local subnet address from the rest
of a given Internet Protocol (IP) address.
Network Time Protocol
(NTP) An Internet standard for Transmission Control Protocol/Internet Protocol
(TCP/IP) networks. NTP synchronizes the clock times of networked devices
with NTP servers to the millisecond using Coordinated Universal Time (UTC).
node An addressable point or device on a network. A node can connect a computing
system, a terminal, or various peripheral devices to the network.
nonmaskable interrupt
(NMI) A system interrupt that is not invalidated by another interrupt.
O
object identifier
(OID) A number that identifies an object’s position in a global object registration tree.
Each node of the tree is assigned a number, so that an OID is a sequence of
numbers. In Internet usage the OID numbers are delimited by dots, for
example, “0.128.45.12.” In the Lightweight Directory Access Protocol (LDAP),
OIDs are used to uniquely identify schema elements, including object classes
and attribute types.
OpenIPMI An operating system-independent, event-driven library for simplifying access
to the Intelligent Platform Management Interface (IPMI).
operator A user with limited privileges to the managed host system.
out-of-band (OOB)
system management Server management capability that is enabled when the operating system
network drivers or the server are not functioning properly.
P
parity Additional information stored with data on a disk that enables the controller to
rebuild data after a drive failure.
