A system for discovery of all devices and drives connected directly or indirectly to a backplane uses a MCU to send a communication to a controller on a platform to determine a type of upstream connection between the backplane and the platform and generate a data structure containing the information. The MCU then searches for ports on the backplane to identify devices directly connected to the backplane. The MCU searches for connectors connected to the ports to identify possible other devices and drives. The MCU searches for slot information for slots connected to the downstream connectors. The connector information, port information and slot information is stored in the data structure and the data structure is communicated to a CPLD on the platform for use by a BIOS.

System and method for automatic identification and bios configuration of drives in a backplane

In one embodiment, a method for enumerating logical identifiers for a plurality of backplanes of an information handling system includes: generating, by each of the plurality of backplanes, inventory information indicating a plurality of backplane attributes; sending, by each of the plurality of backplanes, the inventory information to a baseboard management controller; receiving, by the baseboard management controller, the inventory information from each of the plurality of backplanes; determining, by the baseboard management controller, a backplane topology of the information handling system based on the inventory information, the backplane topology indicating a backplane location for each of the plurality of backplanes; generating, by the baseboard management controller, a logical backplane identifier for each of the plurality of backplanes based on the backplane topology; and assigning, by the baseboard management controller, the logical backplane identifier to each of the plurality of backplanes.

Enumerating logical identifiers for backplanes of an information handling system

A blade server includes two or more server blades where each server blade includes a server, and two or more memory devices. The server blades arbitrate among themselves to designate one of them as a master server blade. The master server blade allocates the memory devices.
