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.
personality
When used in the context of an adapter,
the term personality refers to the entire
adapter. It includes all the I/O ports and
the functions on that adapter. For
example, a QLogic adapter can have dual
personality, converting from Fibre Channel
to Converged Network Adapter or vice
versa. Therefore, all the I/O functions and
all the I/O physical ports on the adapter
changes from Fibre Channel Adapter to
Converged Network Adapter.
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.
point-to-point
Also FC-P2P. Two Fibre Channel nodes
directly connected (not in a loop).
port
Access points in a device where a link
attaches. There are four types of ports, as
follows:
 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.
port instance
The number of the port in the system.
Each adapter may have one or multiple
ports, identified with regard to the adapter
as port 0, port 1, and so forth. To avoid
confusion when dealing with a system
containing numerous ports, each port is
assigned a port instance number when the
system boots up. So port 0 on an adapter
might have a port instance number of 8,
for example, if it is the eighth port discov-
ered by the system.
QoS
Quality of service. Refers to the methods
used to prevent bottlenecks and ensure
business continuity when transmitting data
over virtual ports by setting priorities and
allocating bandwidth.
quality of service
See QoS.
RAID
Redundant array of independent disks.
Fault-tolerant disks that look like either
single or multiple volumes to the server.
redundant array of independent disks
See RAID.
router log
Log of messages describing events that
occur on the intelligent storage router.
