JBOD JBOD stands for just a bunch of disks.
LUN LUN stands for logical unit number, the small integer
handle that identifies a portion of disk storage. A LUN
can consist of a single physical disk or many physical
disks. A physical disk can be broken into multiple LUNs.
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 an HBA port and
a target port. Note that this is distinct from any internal
paths within the network. A 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.
PDU PDU stands for protocol data unit.
Port Ports are access points in a device where a link
attaches.
