Adapter Personality
The term personality refers to the entire
adapter where supported. When used in
this context of an adapter, it includes all
the I/O ports and its functions on that
adapter. For example, a Marvell adapter
can have dual personality—convert from
Fibre Channel Adapter to Converged
Network Adapter or vice versa. Therefore,
all the I/O functions and all the I/O physical
ports on the adapter change from Fibre
Channel to Converged Network Adapter.
Network Partition Function Personality
The term personality refers to a specific
I/O function type on the adapter’s physical
port where supported, not the entire
adapter. When used in the context of a
network partition function, the term is
associated with an individual I/O function
of a physical port. For example, a physical
I/O port can be partitioned into multiple I/O
functions, and an individual I/O function
can be configured with a LAN (NIC) or a
SAN (FCoE or iSCSI) personality.
ping
A computer network tool used to test
whether a specific host is reachable
across an IP network. Ping is also used to
self-test the network interface card of the
computer, or as a speed test.
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.
 F_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 discovered
by the system.
QoS
Quality of service. Refers to the bandwidth
allocation assigned to each partition used
to send and receive data between the
adapter port and connected devices.
Each physical port on a Marvell adapter
can send and receive data at up to
10Gbps in both directions at the same
time. When the physical port is partitioned
into four partitions, the port bandwidth is
divided between each port partition
according to traffic demands.
You can set QoS for each port partition by
setting minimum and maximum percent-
ages of the physical port's bandwidth for
each partition. This feature helps
guarantee a transmission rate for each
partition that requires a specific bandwidth
to run critical applications using port parti-
tions. The setting for a specific QoS can
resolve bottlenecks that exist when virtual
machines (VMs) contend for port
bandwidth.
