Method to connect scalable blade servers in BladeCenter 1.

     Today IBM has scalable systems in a non-Bladecenter environment, such as the x445. The user connects two or more chassis together using long cables, called scalability cables. Two different methods are descibred below to perform scaling

     This invention consists of a BladeCenter chassis, two or more blade servers containing scalable chipsets and BMCs, and a management module that coordinates all the events. The components are connected using one of the two methods shown in the following figures.

The invention operates as follows:
1) The components are inserted into the BladeCenter and powered on.
2) The management module queries the Blade servers via the RS-485 sideband bus to determine their capabilities.
3) If the management module determines that two scalable blades are installed in the system it then places them into compatible groups based on their slot locations.
4) The user, via the management module, configures the scalable blade servers in a group into a single scalable systems. Only scalable blade servers that the user has connected by one of the methods shown above can be configured into scalable

systems.
5) The management module connects to the BMC on each of the scalable blade servers via a sideband bus and transmits the configuration information.
6) The scalable blade's BMC uses this information to configure the scalable blade s...
