12–NIC Partitioning and Bandwidth Management
Configuring for NIC Partitioning
211 BC0054508-00 M
Consider this example configuration: Four functions (or partitions) are configured
with a total of six protocols, as shown in the following.
Function 0
 Ethernet
 FCoE
Function 1
 Ethernet
Function 2
 Ethernet
Function 3
 Ethernet
 iSCSI
1. If Relative Bandwidth Weight is configured as “0” for all four physical
functions (PFs), all six offloads share the bandwidth equally. In this case,
each offload are assigned roughly 16.67 percent of the total bandwidth.
2. If Relative Bandwidth Weight is configured as “25” for all four PFs,
Ethernet and FCoE offloads on function 0 and Ethernet and iSCSI offloads
on function 3 are assigned roughly 12.5 percent of the total bandwidth,
whereas Ethernet offloads on function 1 and function 2 are assigned roughly
25 percent of the total bandwidth.
