4. Click the down arrow and select the NIC partition (NPAR0, NPAR1, NPAR2,
or NPAR3) from the drop-down list.
Information and configuration fields related to the selected NIC partition
include:
 Default MAC Address—The MAC address set at the manufacturer.
 Location—The logical location in the system: PCI bus number, device
number, and function number.
 NPAR PCI Function Number—The function number (0, 1, 2, 3, 4, 5,
6, or 7) of the eight PCIe function numbers claimed by the adapter.
 NPAR Function Type—This field correlates to the personality of the
selected Switch Independent Partitioning (PCIe) function: NIC, iSCSI,
or FCoE.
 Minimum Bandwidth (%)—Use the up and down arrows to scroll
between 0 percent to 100 percent to set the bandwidth you want to
guarantee for data sent over the selected partition. Each additional
percent increments the bandwidth by 100Mbps. For example, setting
the minimum bandwidth to five percent guarantees sending and
receiving data over the selected port at 500Mbps.
 Maximum Bandwidth (%)—The maximum allowed bandwidth is
specified as a percentage of the link speed. Use the up and down
arrows to scroll between 0 percent to 100 percent to set the maximum
bandwidth for data sent over the selected partition. Each additional
percent increments the bandwidth by 100Mbps. For example, setting
the maximum bandwidth to 100 percent allows for sending and
receiving data over the selected partition at up to 10,000Mbps.
5. Repeat the previous step to configure the minimum and maximum
bandwidth on the other partitions.
6. When you are finished setting changes, click Save to save any changes to the
advanced parameters of the adapter.
NOTE
When bandwidth settings exist for both Switch Independent
Partitioning and
DCBX , DCBX takes precedence over Switch
Independent Partitioning. DCBX sets the bandwidth for iSCSI and NIC
traffic, and then Switch Independent Partitioning sets the bandwidth for
the NIC partitions by dividing the NIC bandwidth allocated by DCBX.
For more information, see “Interoperation of Bandwidth Settings for
DCBX and Switch Independent Partitioning” on page 120.
