CONFIGURE SR-IOV (SINGLE ROOT I/O VIRTUALIZATION)
SR-IOV Global Enable. Enable Single Root I/O Virtualization (SR-IOV).
SR-IOV VFs per PF. Configure the number of SR-IOV Virtual Functions (VF) per a PCIe Physical Function (PF). The range
is 0 to 64 in increments of 8 with a default of 16.
SR-IOV Max Chains per VF. Enter the maximum number of transmit and receive queues (such as receive side scaling
(RSS) queues) that can be used for each virtual function. The maximum is 16. This field is available in only the Windows
Server OS.
HARDWARE AND RESOURCE CONFIGURATION WIZARD: INTRODUCTION
The Hardware and Resource Configuration Wizard will help you modify device hardware configuration and resource
configuration. Select a multi-function mode and then click Next.
Multi-Function mode. Displays the multi-function mode.
Number of Partitions. Displays the number of partitions. The value is 4 and cannot be changed.
HARDWARE AND RESOURCE CONFIGURATION WIZARD: PORT CONFIGURATION
Select a port to configure and then click Next.
Flow Control. The possible values are Auto, Tx Pause, Rx Pause, Tx/Rx pause, and Disable. The configuration is done at
the port level and applies to all functions under the port.The flow control value is a default value for the port. The effective
configuration can be different based on the switch port configuration and whether or not DCB/DCBX is enabled.
Link Speed. Configure the link speed. The default speed is 1Gb for 1Gb adapters and 10Gb for 10Gb adapters.
HARDWARE AND RESOURCE CONFIGURATION WIZARD: CONFIGURE RESOURCES
The following are configurable at the function level. Click Next after making changes.
When NIC partitioning is enabled (on NetXtreme II adapters only), four functions are created under each port. The functions
are numbered 0 to 7. All odd function numbers (1, 3, 5, 7) are created on one port and all even functions (0, 2, 4, 6) are
created on the remaining port.
Ethernet/NDIS. Ethernet/NDIS capability is enabled when selected.
iSCSI. iSCSI functionality is enabled when selected.
FCoE. FCoE functionality is enabled when selected (NetXtreme II adapters only).
Maximum Bandwidth (%).
• The maximum bandwidth setting defines an upper threshold value, ensuring that this limit will not be 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.
