ServerMobility
The ServerMobility
™
feature allows you to assign server IP addresses based on their physical
location in a blade chassis. If a server fails, a replacement server can assume the identity of the
failed unit. The replacement can be a new blade server placed into the slot of the failed unit, or it can
be a backup server in another slot.
Information Schemes
When the switch relays a server’s DHCP request, it inserts a specific set of descriptive information
into that request. You can configure one of the following schemes to be inserted:
Virtual MAC information
Chassis information
Switch name information
The following command specifies the desired information scheme:
Each scheme is covered in greater detail in the following sections.
In addition to setting the scheme on the switch, the DHCP server must be configured to work with
ServerMobility (see “Configuration ServerMobility on the DHCP Server” on page 172).
