Media Media are carriers of information. Fibre Channel
supports several different physical media: copper,
multimode optical, and single-mode optical, which differ
mainly in the maximum cable length. All Fibre Channel
protocols are supported on all media.
NIC NIC stands for network interface controller.
NVRAM NVRAM stands for nonvolatile random access memory.
NVRAM configuration settings are stored in NVRAM.
You can configure NVRAM settings or restore them
from a file. These settings are saved in NVRAM and
are retained when power is removed.
ONC ONC stands for open network computing, a remote
procedure call developed by Sun Microsystems.
Path A path to a device is a combination of a QLA2xxx
adapter and a target port. Note that this is distinct from
any internal paths within the fabric network. A fabric
network appears to the operating system as an opaque
network between the adapter (initiator) and the target
port.
Since a path is a combination of an adapter and a target
port, a path 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 makes a difference 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.
Point-to-point Two Fibre Channel nodes directly connected (nonloop).
