Adaptive Networking overview

Adaptive Networking is a suite of tools and capabilities that enable you to ensure optimized

behavior in the SAN. Even under the worst congestion conditions, the Adaptive Networking features

can maximize the fabric behavior and provide necessary bandwidth for high-priority, mission-critical

applications and connections.

The Adaptive Networking suite includes the following features:

• Bottleneck detection

The bottleneck detection feature identifies devices attached to the fabric that are slowing

down traffic. Bottleneck detection does not require a license. See Chapter 13, “Bottleneck

Detection,” for information about this feature.

• Top Talkers

The Top Talkers feature provides real-time information about the top “n” bandwidth-consuming

flows passing through a specific port in the network. Top Talkers requires an Advanced

Performance Monitoring license. See “Top Talker monitors” on page 410 for more information

about this feature.

• Traffic Isolation Zoning

Traffic Isolation Zoning (TI zoning) allows you to control the flow of interswitch traffic by creating

a dedicated path for traffic flowing from a specific set of source ports (F_Ports). Traffic

Isolation Zoning does not require a license. See Chapter 12, “Traffic Isolation Zoning,” for more

information about this feature.
