12–NIC Partitioning and Bandwidth Management
Configuration Parameters
252
83840-546-00 D
Network MAC Address
The MAC address of the port.
iSCSI MAC Address
If an iSCSI adapter is loaded onto the system, the iSCSI MAC address will
appear.
Flow Control
The flow control setting of the port.
Physical Link Speed
The physical link speed of the port, either 1G or 10G.
Relative Bandwidth Weight (%)
The relative bandwidth setting represents a weight or importance of a
particular function. There are up to four functions per port. The weight is
used to arbitrate between the functions in the event of congestion.
The sum of all weights for the functions on a single physical port should be
either
0
or
100
.
A value of
0
for all functions means that each function transmits at 25% of
the physical link speed, not to exceed the
Maximum Bandwidth
setting
1
.
A value for a function between 1 and 100 represents a percentage of the
physical link speed and is used by an internal arbitration logic as an input
value (weight). A higher value causes this function to transmit relatively
more data, compared to a function (on the same port) that has defined a
lower value.
The smallest recommended value for a partition is 10.
Maximum Bandwidth (%)
The maximum bandwidth setting defines an upper threshold value, ensuring
that this limit is not exceeded during transmission. The valid range for this
value is between 1 and 100. The maximum bandwidth value is defined as a
percentage of the physical link speed.
1
A
Relative Bandwidth Weight
value of “0” for all functions (or partitions) causes the bandwidth
allocation to be divided equally among all enabled offloads. A
Relative Bandwidth Weight
value
of “25” for all functions causes bandwidth allocation to be divided equally among all functions.
Please refer to the example below for distinction.
