Limits may be increased once further testing has been completed, even after the release of Fabric OS. For current scalability limits for Fabric OS, refer to the Brocade Scalability Guidelines document, available under the Technology and Architecture Resources section at http://www.brocade.com/compatibility Other Important Notes and Recommendations Adaptive Networking/Flow-Based QoS Prioritization  Any 8G or 4G FC platform running FOS v6.2.2e or lower version of firmware cannot form an E-port with a 16G FC platform when Adaptive Networking QoS is enabled at both ends of the ISL. Users must disable QoS at either end of the ISL in order to successfully form an E-port under this condition. Users can disable QoS via portcfgQos --disable command. Please consult Fabric OS Command Reference manual for details related to portcfgQoS command.  When using QoS in a fabric with 4G ports or switches, FOS v6.2.2 or later must be installed on all 4G products in order to pass QoS info. E_Ports from the DCX to other switches must come up AFTER 6.2.2 is running on those switches. Access Gateway  AG cascading is not supported on Brocade 6510 or Brocade 6505.  Users who want to utilize Access Gateway's Device-based mapping feature in the ESX environments are encouraged to refer to the SAN TechNote GA-TN-276-00 for best implementation practices.
