Figure 36. 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, and
thus allows blades to be swapped without affecting SAN Zoning, iSCSI zoning, or any MAC-dependent
functions. The write-protected FlexAddress SD card comes provisioned with unique pool of 208 MACs
and 64 WWNs. Other types of SD cards inserted into the CMC's SD card slot are ignored.
FlexAddress can be ordered with a new enclosure or implemented on one already owned by a
customer through the purchase of a customer kit. If FlexAddress is purchased with the chassis, it will
be installed and active when the system is powered up. In the case of an existing enclosure,
FlexAddress requires the addition of one FlexAddress SD card to a CMC and an upgrade to the iDRAC
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. When
redundant CMCs are installed, it is not necessary to put such an SD card in both CMCs, since the
WWN/MAC addresses are pushed to the chassis Control Panel upon enablement 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 as they already have their WWN/MACs
programmed into their controllers. If a replacement of the control panel is required, the SD card will
push the WWN/MACs back to it. It is important to note that the chassis Control Panel also stores CMC
configuration information, so it is advisable that customers keep a backup of the CMC configuration
file.
