Flow Generator:
Flow generator is a test traffic generator for pre-testing the SAN infrastructure (including
internal connections) for robustness before deploying the applications.
Allows users to configure a16G FC capable port as a simulated device that can transmit
frames at full 16G line rate.
Users can emulate a 16G SAN without actually having any 16G hosts or targets or SAN-
testers, and pre-test the entire SAN fabric including optics and cables on ISLs, internal
connections within a switch, at full line rate.
The traffic generator port must be a 16G FC capable port while the traffic destination port can
be an 8G or a16G capable FC port on any switch in the fabric (the test traffic is terminated at
the destination port and does not leave the switch).
Flow Mirror:
Provides the ability to non-disruptively create copies of application flows that can be captured
for deeper analysis. Only mirroring to the CPU of the switch is supported in FOS v7.2.
Used for in-depth analysis of flows of interest SCSI Reservation frames, ABTS frames, flows
going to a bottlenecked device, frames during link bring up, etc.
Users can select the type of frames to be mirrored.
Supported only on 16G FC capable platforms.
Note:
Flow Vision features require the Fabric Vision license or both Fabric Watch and APM licenses.
FCR Enhancements
FOS v7.2 supports the following FCR enhancements:
EX_Port support on optical ICLs of DCX 8510
Provides the ability to configure EX_Ports on the ICL links of DCX 8510 platforms connected
to other DCX 8510 platforms.
Allows users to build very high performance IFLs (Inter Fabric Links) using ICLs simplifies
cabling as well.
Supported only when Virtual Fabrics (VF) is enabled on DCX 8510.
Increased FCR scalability: FOS v7.2 supports up to 6000 devices per edge fabric (an increase from
2000). Refer to the Brocade SAN Scalability Guidelines document for more information.
Routing enhancements to select the lowest cost links in the FCR fabric when there are multiple routes
available between FCR edge fabrics through an FCR backbone fabric.
FCIP Enhancements
FOS v7.2 adds support for a new FCIP Tunnel failover configuration option that provides the following
capabilities:
Allows a user to define a Failover Group that includes a subset of the circuits in the FCIP Tunnel.
Provides a more deterministic failover configuration that would allow a mixture of metric 0 and metric
1 circuits to be used in the event of a metric 0 circuit failure.
