Adaptive Networking overview
Adaptive Networking is a suite of tools and capabilities that enable you to ensure optimized
behavior in the SAN. Under the worst congestion conditions, Adaptive Networking 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. Refer to Chapter 15, “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 a Fabric Vision
license or an Advanced Performance Monitoring license. Refer to “Top Talker monitors” on
page 562 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. Refer to Chapter 13, “Traffic Isolation Zoning,” for
more information about this feature.
