Owner's manual

N
NetWare Loadable
Module (NLM)
Executables that run under the Novell NetWare operating system.
NetWare
Peripheral
Architecture
(NWPA)
The goal of the NetWare Peripheral Architecture (NWPA) is to provide NetWare Version 4.x,
and IntranetWare customers with broader and more reliable driver support for host adapters and
storage devices.
Network Interface
Controller (NIC)
An adapter card installed in a PC, workstation, or server that allows the PC or workstation to
communicate with other devices connected to the same network. This term usually implies a local
area network (LAN) adapter card.
O
Out of Band The capacity to deliver information by modem. Synonymous with “off the network.”
P
Physical Drive Multiple physical drives connected in a HP Array Controller to the same controller and combined
to create logical drives. The logical drives use all of the available physical drive capacity as if it
were a larger drive subsystem. By combining several physical drives, you can use special fault
tolerance and performance features.
Point-to-Point
Protocol (PPP)
A standard defined by the Internet Engineering Task Force. PPP provides a standard method for
transporting multiple protocols over a point-to-point link.
S
Simple Network
Management
Protocol (SNMP)
SNMP defines a set of commands that a management application uses to retrieve or change the
values of items a management agent makes available.
SNMP Multiplexing
(SMUX)
The protocol defining a mechanism for communication between SNMP agent and multiple user
daemons (called SMUX peers). The SMUX protocol has the advantage of being
vendor-independent. With SMUX, a single SNMP agent can be used to control and monitor
devices from different vendors, regardless of how each vendor has implemented SMUX peers in
their own products.
T
Threshold A preset limit that produces an alarm when reached or exceeded.
Trap An indicator of a change or an error condition. Also called alarm.
U
Uninterruptible
Power Supply
(UPS)
A battery that supplies continuous power to a computer system in the event of a power failure.
W
Windows
Management
Instrumentation
(WMI)
Windows 2000 and Windows 98 extensions to WDM which provide an interface between the
operating system and instrumented components, allowing the instrumented components to provide
information and notifications.
