BX Blade Server System Overview Blade server management

2.2.2 Redundancy of the ServerView Management Blade

Of the two ServerView management blades within the blade server system, one will take over the role of the
master, who is in charge of the server management, while the other one will remain in a standby status as a
redundant component. The two components have the same IP address, but their MAC adresses differ from each
other.
The management blade in slot 1 becomes the master management blade by default.
The master blade and the redundant blade communicate symmetrically with each other via a TX/RX serial
interface. As soon as the master fails to work properly, for instance, when unplugged by the system administrator,
the standby component will take over control of the server management.
Fail-over scenario
When the redundant ServerView management blade takes over control from the master, it will behave according
to the following scenario:
– Issue an ICMP broadcast ping to update the ARP table and connection the IP filtering table, in order to adjust
them with regard to the new MAC address
– Define a proprietary protocol in L2, which is used for remote communication
If communication between master and redundant component via the serial interface has broken down, these
components can continue to communicate by sending IP broadcast packages, using the MAC addresses.

2.2.3 Console Redirection

When using the console redirection feature, the management of the blade server system may be executed in
remote control mode. To support this mode, the ServerView management blade acts as the console redirection
agent.
