WWN settings
At this point in the wizard, you are asked to select the type of FC WWNs to be used on the server blades
within the enclosure. You can choose to use the server factory default WWNs that came with the FC HBA
mezzanine card or to use FC WWNs assigned by Virtual Connect. Be sure to fully understand the
following information before making this selection.
Each server blade FC HBA mezzanine card ships with factory default port and node WWNs for each FC
HBA port. Each WWN is a 64-bit number that uniquely identifies the FC HBA port/node to other devices
on the network. While the hardware ships with default WWNs, Virtual Connect has the ability to assign
WWNs that will override the factory default WWNs while the server remains in that Virtual Connect
enclosure. When configured to assign WWNs, Virtual Connect securely manages the WWNs by
accessing the physical FC HBA through the enclosure Onboard Administrator and the iLO interfaces on
the individual server blades.
When assigning WWNs to a FC HBA port, Virtual Connect will assign both a port WWN and a node
WWN. Because the port WWN is typically used for configuring fabric zoning, it is the WWN displayed
throughout the Virtual Connect user interface. The assigned node WWN is always the same as the port
WWN incremented by one.
Configuring Virtual Connect to assign WWNs in server blades maintains a consistent storage identity
(WWN) even when the underlying server hardware is changed. This method allows server blades to be
replaced without affecting the external Fibre Channel SAN administration.
