QoS zones
18
For example,
Figure 61
shows a fabric with two hosts (H1, H2) and three targets (S1, S2, S3). The
traffic prioritization is as follows:
•
Traffic between H1 and S1 is high priority.
•
Traffic between H1 and S3 and between H2 and S3 is low priority.
•
All other traffic is medium priority, which is the default.
FIGURE 61
QoS traffic prioritization
For this fabric, you could set up the following QoS zones:
QOSH_Zone1
Members: H1, S1
QOSL_Zone3
Members: H1, H2, S3
QoS on E_Ports
In addition to configuring the hosts and targets in a zone, you must also enable QoS on individual
E_Ports that might carry traffic between the host and target pairs. Path selection between the
“host,target” pairs is governed by FSPF rules and is not affected by QoS priorities. For example, in
Figure 62
, QoS should be enabled on the encircled E_Ports.
NOTE
By default, QoS is enabled on 8 Gbps ports, except for long-distance 8 Gbps ports. QoS is disabled
by default on all 4 Gbps ports and long-distance 8 Gbps ports.
