Fabric OS v7.0.1a Release Notes v1.0 Page 16 of 74
4
McDATA 1620 and 2640 SANRouters should not be used with FOS-based routing (FCR) for connections to the same
edge fabric.
5
FA4-18 is not supported in a DCX/DCX-4S that is running FOS v7.0 or later
6
If operating with FOS v6.2.2e or earlier, Adaptive Networking QoS must be disabled when connecting to 16G FC
platform. Otherwise, ISL will segment.
7
Connectivity to FC SAN is established via VDX6730 connected to FCR running FOS v7.0.1 or later. FCR platforms
supported include 5100, VA-40FC, 5300, 7800, DCX, DCX-4S, DCX 8510-8, DCX 8510-4, 6510. For higher FCR
backbone scalability (refer to separate ―Brocade SAN Scalability Guidelines‖ documentation for details), please use
5300, DCX, DCX-4S, DCX 8510-8, DCX 8510-4.
Zoning Compatibility Note:
Users are recommended to upgrade to the following versions of firmware when interoperating with a switch
running FOS v7.0 or later in the same layer 2 fabric to overcome some of the zoning operations restrictions
that otherwise exist:
Main code level
Patch code levels with full zoning
compatibility
FOS v6.2
FOS v6.2.2d or later
FOS v6.3
FOS v6.3.2a or later
FOS v6.4
FOS v6.4.1 or later
If there are switches running FOS versions lower than the above listed patch levels in the same fabric as a
switch with FOS v7.0 or later, then cfgsave and cfgenable operations initiated from these switches will fail if
the zoning database is greater than 128KB. In such scenarios zoning operations such as cfgsave/cfgenable
can still be performed successfully if initiated from a switch running FOS v7.0 or later.
