9.5 FlexAddress
FlexAddress™ delivers persistent storage and network identities, equipping a data center to handle
predictable or even unplanned changes—increase, upgrade, or replace servers without affecting the
network or storage and minimizing downtime.
Dell’s patent-pending FlexAddress technology allows any M-Series blade enclosure to lock the World
Wide Name (WWN) of the Fibre Channel controller and Media Access Control (MAC) of the Ethernet
and iSCSI controller into a blade slot, instead of to the blade’s hardware as was done in the past. By
removing the network and storage identity from the server hardware, customers are now able to
upgrade and replace components or the entire server without changing the identity on the network.
This technology works with any vendor’s installed I/O module as well as with Dell PowerConnect™
products.
FlexAddress delivers the ability to:
• Service a blade or I/O mezzanine card, upgrade the I/O mezzanine cards to newer
technology, or upgrade the entire server with new technology while maintaining the mapping
to Ethernet and storage fabrics. This capability allows quick, painless connection and reduces
downtime. This capability is especially powerful when operating in a boot from SAN
environment.
• Quickly obtain a list of all MAC/WWNs in the chassis by slot and be assured these will never
change.
• Efficiently integrate into existing management and network infrastructure.
