Quality of Service
Quality of Service (QoS) 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 QLogic 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
percentages of the physical port’s bandwidth for each partition. This feature helps
guarantee a transmission rate for each partition that requires a particular
bandwidth to run critical applications using port partitions. The setting for a given
QoS can resolve bottlenecks that exist when VMs contend for port bandwidth.

a
The physical port number is displayed as Port 1 or Port 2 on the adapter’s port’s label.
b
The physical port number is displayed as Phy Port 0 or Phy Port 1 on the Switch Independent
Partitioning configuration screens for most of the management tools, except where noted otherwise.
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.
