NPAR
NIC partitioning. The division of a single
NIC port into multiple physical functions or
partitions, each with a user-configurable
bandwidth and personality (interface type).
Personalities include NIC, FCoE, and
iSCSI.
NPIV
N_Port ID virtualization. The ability for a
single physical Fibre Channel end point
(N_Port) to support multiple, uniquely
addressable, logical end points. With
NPIV, a host Fibre Channel Adapter is
shared in such a way that each virtual
adapter is assigned to a virtual server and
is separately identifiable within the fabric.
Connectivity and access privileges within
the fabric are controlled by identification of
each virtual adapter and, hence, the virtual
server using each virtual adapter.
operating system
See OS.
OS
Operating system. After being loaded by
the boot program, the program that
manages all other programs on a
computer.
path
A path to a device is a combination of a
adapter port instance and a target port as
distinct from internal paths in the fabric
network. A fabric network appears to the
operating system as an opaque network
between the adapter (initiator) and the
target.
Because a path is a combination of an
adapter and a target port, it is distinct from
another path if it is accessed through a
different adapter and/or it is accessing a
different target port. Consequently, when
switching from one path to another, the
driver might be selecting a different
adapter (initiator), a different target port, or
both.
This is important to the driver when
selecting the proper method of failover
notification. It can make a difference to the
target device, which might have to take
different actions when receiving retries of
the request from another initiator or on a
different port.
PCI Express (PCIe)
A third-generation I/O standard that allows
enhanced Ethernet network performance
beyond that of the older peripheral compo-
nent interconnect (PCI) and PCI extended
(PCI-x) desktop and server slots.
ping
A computer network administration utility
used to test whether a specified host is
reachable across an IP network, and to
measure the round-trip time for packets
sent from the local host to a destination
computer.
port
Access points in a device where a link
attaches. The four types of ports are:
 N_Port—a Fibre Channel port that
supports point-to-point topology.
 NL_Port—a Fibre Channel port that
supports loop topology.
 FL_Port—a port in a fabric where an
N_Port can attach.
 FL_Port—a port in a fabric where an
NL_Port can attach.
