NEO 200s/400s User Guide
NIC
Short for Network Interface Card. A board that provides network communication
capabilities to and from a computer.
NIS
Short for Network Information Service. A network naming and administration system for
smaller networks that was developed by Sun Microsystems. NIS+ is a later version that
provides additional security and other facilities.
NL_port
A Node Loop port is capable of arbitrated loop functions and protocols. An NL_Port connects
via an arbitrated loop to other NL_Port and at most a single FL_Port. NL_Ports handle
creation, detection, and flow of message units to and from the connected systems. NL_Ports
are end ports in virtual point-to-point links through a fabric, for example NL_Port to F_Port
to F_Port to N_Port using a single Fibre Channel fabric switch. In the absence of a fabric
switch FL_Port, NL_Ports can communicate with other NL_Ports in virtual point-to-point
links through a FC-AL open loop circuit often through FC-AL (Arbitrated Loop) hub or loop
switch devices.
Node
Any device, including servers, workstations, or tape devices, that are connected to a
network; also the point where devices are connected.
Node Name
This is an eight-byte, 16-character hexadecimal number, uniquely identifying a single fibre
device. It incorporates the World Wide Name and two additional bytes that are used to
specify the format. In a host system with multiple FC ports, all adapters typically use the
same Node Name, but unique Port Names.
NTFS
Short for New Technology File System. The standard file system used by Windows NT and
later versions of the Windows operating system.
NTP
Short for Network Time Protocol. A protocol for synchronizing the system clocks of
computers over a packet-switched network.
NVRAM
Abbreviation of Non-Volatile Random Access Memory, a type of memory that retains its
contents when power is turned off.
OCP
Short for Operator Control Panel. The OCP touch screen is a 2.5" x 1.25" (6.4cm x 3.2cm)
pressure-sensitive blue and light-gray screen that provides an easy way to directly
communicate with the unit. It provides text and graphic messages and, through the use of
virtual buttons and sliders, allows users to make changes to current settings.
Permissions
A security category, such as no access, read-only, or read-write, that determines what
operations a user or group can perform on folders or files.
