 Bottleneck Detection integration with MAPS dashboard
Bottleneck Detection information is integrated with MAPS dashboard. The “Summary” section of the
dashboard shows bottleneck events detected by the Bottleneck Monitor. The “History” section of the
dashboard shows entries for bottlenecked ports, including transient bottlenecks that are not detected by
the Bottleneck Monitor. This enables users to get at an instant view of the bottlenecked ports in the switch
and enables rapid problem resolution.
 Proactive Flow Monitoring using MAPS
MAPS can monitor flows created under Flow Vision’s “monitor” sub-feature and generate alerts based on
user defined rules. To monitor a flow using MAPS, users must first create and activate the flows using Flow
Monitor, and then import those flows into MAPS for monitoring. This enables users to monitor and be
alerted on various conditions such as, when bandwidth utilization at a port for a given flow exceeds a
certain threshold or falls under a certain threshold, when number of SCSI reservation frames at a LUN
exceeds a certain threshold, etc.
 Automated Migration of existing Fabric Watch configuration to MAPS
Users who are currently monitoring a switch using Fabric Watch can automatically import all of their Fabric
Watch thresholds into a MAPS policy, allowing them to seamlessly migrate from Fabric Watch to MAPS.
This allows users to retain monitoring behaviors that have been developed for their unique environment
over time, and also take advantage of the powerful new capabilities in MAPS and usability improvements.
(Note that the Fabric Watch and MAPS features are mutually exclusive on an individual switch. Only one or
the other can be active at one time.)
Flow Vision
Flow Vision is a key component of Brocade’s Fabric Vision technology being introduced in FOS v7.2 that
provides comprehensive visibility into application flows in the fabric and the ability to non-disruptively create
copies of the application flows that can be captured for deeper analysis. Flow Vision also provides test flow
generation capability that can be utilized to pre-test a SAN infrastructure for robustness before deploying
applications. The test flow generation capability is also useful for testing the internal connections on a switch
to ensure ideal performance before deploying the switch into a production environment.
Flow Vision includes the following key features:
 Flow Monitor:
 Provides comprehensive visibility into application flows in the fabric, including the ability to
learn (discover) flows automatically.
 Enables monitoring of application flows (Example: From a Host to a Target/LUN) within a
fabric at a given port.
 Provides statistics associated with the specified flows to gain insights into application
performance. Some of these statistics include:
 Transmit frame count, receive frame count, transmit throughput, receive throughput,
SCSI Read frame count, SCSI Write frame count, number of SCSI Reads and Writes
per second (IOPS), etc.
 When NPIV is used on the host, users can monitor VM (Virtual Machine) to LUN level
performance as well.
 Enables monitoring of various frame types at a switch port to provide deeper insights into
storage I/O access pattern at a LUN, reservation conflicts, and I/O errors.
 Example: SCSI Read, SCSI Write, SCSI Reserve, ABTS, BA_ACC, etc.
 Integrated with MAPS to enable threshold based monitoring and alerting of flows.
