Using FlexAddress and FlexAddress Plus
cards
This section provides information about FlexAddress and how to use FlexAddress Plus card to configure
FlexAddress.
NOTE: The FlexAddress feature is licensed. This feature license is included in the Enterprise License.
About FlexAddress
FlexAddress allows CMC to assign WWN/MAC IDs to a particular slot and override the factory IDs. Hence,
if the server module is replaced, the slot based WWN/MAC IDs remain the same. This feature eliminates
the need to reconfigure Ethernet network management tools, SAN resources, DHCP servers, and routers
for various fabrics for a new server module.
Every server module is assigned unique WWN and/or MAC IDs as part of the manufacturing process.
Without FlexAddress, if a server had to be replaced with another server module, the WWN/MAC IDs
changes and Ethernet network management tools and SAN resources had to be reconfigured to identify
the new server module.
If the server is inserted in a new slot or chassis, the server-assigned WWN/MAC is used unless that chassis
has the FlexAddress feature enabled for the new slot. If you remove the server, it will revert to the server-
assigned address.
Additionally, the override action only occurs when a server module is inserted in a FlexAddress enabled
chassis; no permanent changes are made to the server module. If a server module is moved to a chassis
that does not support FlexAddress, the factory-assigned WWN/MAC IDs is used.
CMC FX2/FX2S chassis is shipped with the FlexAddress Plus SD card, which supports FlexAddress,
FlexAddress Plus, and Extended Storage features.
NOTE: Data contained on the FlexAddress Plus SD card is encrypted and may not be duplicated or
altered in any manner, because it may inhibit system function and cause the system to not function
properly.
NOTE: The use of a FlexAddress Plus SD card is limited to one chassis only. You cannot use the
same FlexAddress Plus SD card on another chassis.
About FlexAddress Plus
Each FlexAddress Plus feature card contains unique pool of MAC/WWNs that allow the chassis to assign
World Wide Name/Media Access Control (WWN/MAC) addresses to Fibre Channel and Ethernet devices.
Chassis assigned WWN/MAC addresses are globally unique and specific to a server slot.
