Fast!UTIL
QLogic Fast!UTIL™ Fibre Channel Adapter
BIOS utility.
Fibre Channel
High-speed serial interface technology that
supports other higher layer protocols such as
SCSI and IP, and is primarily used in SANs.
Standardized under ANSI in 1994.
Fibre Channel over Ethernet (FCoE)
Fibre Channel over Ethernet. A new technology
defined by the T11 standards body that allows
traditional Fibre Channel storage networking
traffic to travel over an Ethernet link by encap-
sulating Fibre Channel frames inside Layer 2
Ethernet frames. For more information, visit
www.fcoe.com.
Flash
Nonvolatile memory where the boot code is
saved. At times, Flash and boot code are used
interchangeably.
Internet protocol (IP)
A method by which data is sent from one
computer to another over the Internet. IP speci-
fies the format of packets, also called
datagrams, and the addressing scheme.
Internet small computer system interface
(iSCSI)
Protocol that encapsulates data into IP packets
to send over Ethernet connections. An alterna-
tive to FCIP.
load balancing
A software feature that improves system perfor-
mance by balancing device access between
multiple ports or adapters for maximum
resource efficiency.
local area network (LAN)
Network typically with transmissions less than
5km.
logical unit number (LUN)
A subdivision of a SCSI target. It is the small
integer handle that differentiates an individual
disk drive or partition (volume) within a common
SCSI target device such as a disk array.
8200 Series Converged Network Adapter and 3200 Series Intelligent Ethernet Adapter
Technically, a LUN can be a single physical disk
drive, multiple physical disk drives, or a portion
(volume) of a single physical disk drive.
However, LUNs are typically not entire disk
drives but rather virtual partitions (volumes) of a
RAID set.
Using LUNs, the Fibre Channel host can
address multiple peripheral devices that may
share a common controller.
loopback
Diagnostic tool that routes transmit data through
a loopback connector back to the same adapter.
message signaled interrupts (MSI/MSI-X)
One of two PCI-defined extensions to support
message signaled interrupts (MSI), in PCI 2.2
and later and PCIe. MSIs are an alternative way
of generating an interrupt through special
messages that allow emulation of a pin asser-
tion or deassertion.
MSI-X (defined in PCI 3.0) allows a device to
allocate any number of interrupts between 1
and 2048 and gives each interrupt separate
data and address registers. Optional features in
MSI (64-bit addressing and interrupt masking)
are mandatory with MSI-X.
network interface controller/card (NIC)
A computer circuit board or card that is installed
in a computer so that it can be connected to a
network.
node port (N_Port)
Node port. A port that connects by a
point-to-point link to either a single N_Port or a
single G_Port. N_Ports handle creation, detec-
tion, and flow of message units to and from the
connected systems. N_Ports are end ports in
virtual point-to-point links through a fabric, for
example N_Port to F_Port to F_Port to N_Port
using a single Fibre Channel fabric switch.
