QoS zones
18
•
QoS over FC routers is supported only in an edge-to-edge fabric configuration; it is not
supported in a backbone-to-edge fabric configuration. You cannot prioritize the flow between a
device in an edge fabric and a device in the backbone fabric.
•
QoS over FC routers is supported only if Virtual Fabrics is disabled in the backbone fabric. QoS
over FC routers cannot be enabled if Virtual Fabrics is also enabled in the backbone fabric.
•
The port WWN of the host or target and the port WWN of the proxy device must be in both an
LSAN zone and a QoS zone.
•
QoS over FC routers is supported on both EX_Ports and VEX_Ports. QoS over FC routers is not
supported on the FR4-18i blade.
•
The EX_Ports (or VEX_Ports) in the path between the QoS devices must be on switches running
Fabric OS v6.3.0 or later.
•
QoS zones must use WWN notation only; D,I notation is not supported for QoS over FCR.
•
An Adaptive Networking license must be installed on every switch that is in the path between a
given configured device pair, including the switches in the backbone fabric and both edge
fabrics.
Virtual Fabric considerations for traffic prioritization
You can prioritize flows between devices in a logical fabric. The priority is retained for traffic going
across ISLs and through the base fabric XISLs.
For example,
Figure 63
shows a logical fabric that includes H1 and S1. To set the traffic between
H1 and S1 to high priority, create a QoS zone in the logical fabric with H1 and S1 as members. Then
enable QoS on all of the E_Ports shown circled in the figure, including all of the E_Ports in the XISLs
(ports 10, 11, 12, 13, 14, 15, 16, and 17).
