Method for determining intelligent platform management bus (IPMB) addresses of block multiplexer channels (BMC) of blade servers

Abstract

The invention discloses a method for determining the IPMB addresses of BMCs of blade servers and belongs to the technical field of blade server communication. The method adopts a structure which comprises management module and blade servers, wherein the management module performs data interaction with the BMC of each blade server through an IPMB bus. The structure is characterized in that: each IPMB bus is provided with an electrically programmable read-only-memory (EPROM) for storing the IPMB address of the BMCs of the blade servers; the management module writes the specified IPMB addresses of the BMCs of the blade servers in the EPROMs in the buses when starting for the first time; and when inserted, the blade servers can configure the IPMB addresses of the BMCs of the blade servers by reading the IPMB addresses in the EPROMs. The management module can change the IPMB addresses of the BMCs of the blade servers flexibly according to needs, thereby improving the safety of the IPMB addresses.

Description

technical field [0001] The invention relates to the technical field of blade server communication, in particular to a method for determining the IPMB address of the blade server BMC. Background technique [0002] Blade servers are favored by users for their high computing density, maximum possible space saving, ease of centralized management, and simple deployment. Among them, the blade management system has gradually become an important way for different manufacturers to display their technical characteristics. [0003] Such as figure 1 As shown, the current blade management is mainly in this way, and the management module performs data interaction with each blade's own BMC (Baseboard Management Controller) through the IPMB bus (Intelligent Platform Management Bus). But the premise of this interaction is that the management module must know the IPMB address of each blade BMC. According to the IPMI protocol, the communication between the management module and the blade mos...

Problems solved by technology

The two parties using the IPMB communication method must each have an IPMB address. Among them, there is only one address of the management module, which is easy to determine, but the IPMB address of each blade must be different, and it is usually determined by reading the fixed hardware configuration from the blade BMC. The management module cannot be modified

[0004] Most of the current blade servers are plugged into the backplane, so many manufacturers confirm the IPMB address of the local BMC through the high and low levels of 4-5 pins of the blade. Simple, but the disadvantage of this method of using hardware to determine the IPMB address is that the person who makes the management module firmware must first look at the schematic diagram of the backplane to know the status of the IPMB address line of each blade, and once determined, it cannot be changed. poor flexibility
