Figure 16. FlexAddress addresses

FlexAddress replaces the factory-assigned World Wide Name/Media Access Control (WWN/MAC)
IDs on a blade with WWN/MAC IDs from the FlexAddress SD card associated with that slot. This
user-configurable feature enables a choice of iSCSI MAC, Ethernet MAC, and/or WWN persistence
enabling blades to be swapped without affecting SAN zoning, iSCSI zoning, or any MAC-dependent
functions. The write-protected FlexAddress SD card comes provisioned with a unique pool of 208
MACs and 64 WWNs. Other types of SD cards inserted into the CMC's SD card slot are ignored.
You can order FlexAddress with a new enclosure, or implement FlexAddress for an existing
enclosure by purchasing a customer kit. If you purchase FlexAddress with an enclosure, it will be
active when the system is powered up. For an existing enclosure, you will need to add a FlexAddress
SD card to the CMC, and upgrade the iDRAC with Lifecycle Controller firmware, Ethernet and Fibre
Channel controllers' firmware, server BIOS, and CMC firmware. All blades and CMC must have the
correct versions of firmware to properly support this feature. If you install redundant CMCs, it is not
necessary to add an SD card to both CMCs since the WWN/MAC addresses are pushed to the
chassis control panel when enabled for redundancy. If one CMC becomes inoperable, the other
CMC still has access to the WWN/MAC addresses in the control panel. Blades that are up and
running are not affected since they already have their WWN/MACs programmed into their
controllers. If you replace the control panel, the SD card will push the WWN/MACs back to the
replacement control panel. Additionally, the chassis control panel also stores CMC configuration
information, so keeping a backup of the CMC configuration file it recommended.
