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.
OptionROM OptionROM is a nonvolatile memory where the boot
code is saved. At times, OptionROM and boot code are
used interchangeably. See Boot code.
Path A path to a device is a combination of a
QLA200/QLA2xxx HBA port 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 HBA
(initiator) and the target port.
Since a path is a combination of an HBA and a target
port, a path is distinct from another path if it is accessed
through a different HBA and/or it is accessing a different
target port. Consequently, when switching from one
path to another, the driver might be selecting a different
HBA (initiator), a different target port, or both.
Point-to-point Two Fibre Channel nodes directly connected (nonloop).
