Scalability
All scalability limits are subject to change. 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

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.
• When FOS is upgraded from v7.1.x to v7.2.0 or later:
• If the Adaptive Networking license was NOT installed in v7.1.x, all ports will have QOS disabled
following the firmware upgrade and links will come up in normal mode.
• If the Adaptive Networking license was installed in v7.1.x, there will be no change in port QOS
mode following the upgrade.
 If the remote port supports QOS and QOS is not explicitly disabled on the local or
remote port, the link will come up in QOS mode.
