I/O Adapter Module (IOAM)
I/O Adapter Module (IOAM). A collection of modular components that provides I/O
connectivity and can include ServerNet switch boards, Gigabit Ethernet 4-port
ServerNet adapters (G4SAs), Fibre Channel ServerNet adapters (FCSAs), fans, and
power supplies. In the IOAM, each module is a logical entity that represents a single
service domain.
I/O Adapter Module Enclosure (IOAM Enclosure). The sheet-metal carrier that is installed
in a standard 19-inch rack and contains the IOAM components.
KB. See kilobyte (KB).
Kbps. Kilobits/second. A data rate equal to 1000 bits/second (bps). See also bits/second
(bps) and megabits/second (Mbps).
KBps. Kilobytes/second. A data rate equal to 1024 bytes/second.
KByte. kilobyte (KB)
kilobyte (KB). A unit of measurement equal to 1024 bytes.
LAN. See local area network (LAN).
local area network (LAN). A network that is located in a small geographical area and
whose communications technology provides a high-bandwidth, low-cost medium to
which low-cost nodes can be connected. One or more LANs can be connected to the
system such that the LAN users can access the system as if their workstations were
connected directly to it. Contrast with wide area network (WAN).
Mbps. See megabits/second (Mbps).
megabits/second (Mbps). A data rate equal to 1,048,576 bits/second (bps).
MHz. Megahertz. One million cycles/second.
modem. A device for performing necessary signal transformation between terminal devices
and data communications lines. Modems are used in pairs, one at either end of a data
communications line. See also data circuit-terminating equipment (DCE) and data
terminal equipment (DTE).
multiplexed. The action of separating data traffic from one line onto several distinct lines or
of combining data traffic from several distinct lines into one line.
OSM. Stands for HP Open System Management (OSM) Interface. OSM replaces TSM as
the system management tool of choice for NonStop S-series servers. OSM provides
the same functionality as TSM while overcoming limitations of TSM. OSM is required
for support of new functionality in G06.21 and later and is the only supported
management tool for Integrity NonStop NS-series servers.
