IOP
controllers (S-SACs) in a single unit. (2) A collective term for both IOMF CRUs and
IOMF 2 CRUs when a distinction between the two types of CRUs is not required.
IOP. See input/output process (IOP).
IP. See Internet protocol (IP).
IP address. An address that identifies a specific host to the Internet protocol (IP). An IP
address consists of two parts: a network address, which identifies the network, and a
local address, which identifies a host within a network. A network address is
concatenated with a host address to form the IP address and uniquely identify a host
within a network. IP routes data between source and destination IP addresses.
IPC. See interprocessor communication (IPC).
KB. See kilobyte (KB).
Kernel subsystem. In G-series RVUs, the subsystem for configuration and management of
the Subsystem Control Facility (SCF) subsystem managers that are generic
processes, some system attributes, and the ServerNet X and Y fabrics.
Kernel subsystem manager process. The generic process that starts and manages other
generic processes, some system attributes, and the ServerNet X and Y fabrics in
G-series RVUs. The $ZZKRN Kernel subsystem manager process is started and
managed by the $ZPM persistence manager process. See also generic process.
kilobyte (KB). A unit of measurement equal to 1024 bytes. See also gigabyte (GB),
megabyte (MB), and terabyte (TB).
LAN. See local area network (LAN).
layered topology. The network topology for ServerNet clusters using the HP NonStop
ServerNet Switch (model 6780). The layered topology can scale by adding cluster
switch layers or zones. The layered topology supports up to four layers and three
zones. See also star topologies
.
LIF. See logical interface (LIF)
.
line. The specific hardware path over which data is transmitted or received. A line can also
have a process name associated with it that identifies an input/output process (IOP) or
logical device associated with that specific hardware path.
line-handler process. See Expand line-handler process or Expand-over-ServerNet
line-handler process (Expand/SvNet).
linker. The process or server that invokes the message system to deliver a message to
some other process or server.
