Upgrade considerations

The maximum logins per switch has decreased with Fabric OS v6.4.0. When upgrading from a
release previous to Fabric OS v6.4.0 and later, the configured maximum is carried forward and may
exceed the Fabric OS v6.4.0 limit. It is recommended to reconfigure this parameter to be within the
range permitted in Fabric OS v6.4.0 and later.

Fixed addressing mode

Fixed addressing mode is the default addressing mode used in all platforms that do not have
Virtual Fabrics enabled. When Virtual Fabrics is enabled on the Brocade DCX and DCX-4S, fixed
addressing mode is used only on the default logical switch. The number of NPIV devices supported
on shared area ports (48-port blades) is reduced to 64 from 128 when Virtual Fabrics mode is
enabled.

10-bit addressing mode

The 10-bit addressing mode is the default mode for all the logical switches created in the Brocade
DCX and DCX-4S Backbones. The number of NPIV or loop devices supported on a port is 64.

Table 64

shows the number of NPIV devices supported on the Brocade DCX and DCX-4S

Backbones.
