Problems solved by technology

[0004] Generally speaking, the RMC can automatically update the firmware used after receiving the firmware update file. However, if it is accidentally interrupted during the execution of the update program (for example, the machine crashes or the power supply of the cabinet is interrupted), or If the firmware is updated to the wrong firmware, the RMC may not be able to boot normally after restarting
Because in the current technology, only one RMC is configured in a cabinet, if the RMC cannot be started normally, all the servers in the cabinet will not be able to be used normally, which is very troublesome
[0005] Furthermore, since the RMC cannot be started normally after the firmware update fails, the cabinet cannot update the firmware again without external support (such as manually performed by the administrator), so as to Troubleshoot error conditions

Embodiment Construction

[0072] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0073] See first figure 1 , is a schematic diagram of the cabinet of the first embodiment of the present invention. figure 1 A cabinet 1 is disclosed, and the cabinet 1 has a plurality of accommodation slots for setting multiple sets of endpoint servers 4 . The cabinet 1 also includes multiple sets of cabinet management modules, which are respectively electrically connected to the endpoint servers 4 to collect information about the endpoint servers 4 and to control the endpoint servers 4 . In this embodiment, the multiple sets of rack management modules take a first rack management module 2 and a second rack management module 3 as examples for illustration, but the number is not limited to two groups.

[0074] In the present invention, each rack management module includes a rack management controller (Rack Management Controller, RMC), a switch...

Abstract

The invention discloses a rack with a plurality of rack management modules and a method for updating firmware thereof. Each rack management module includes a Rack Management Controller (RMC), a switcher and an internal storage; the switchers of all the rack management modules are connected each other, and firmware is stored in all the internal storages. When the RMC receives a firmware update file and an update command uploaded from an external device, the RMC issues a switching command to the switcher to command the switcher to switch to of the internal storage of the other rack management module; and when the RMC executes the firmware update program, update of the firmware in the internal storage of the other rack management module is performed through connection of the switchers. Through the rack and the method, the problem that the RMC cannot normally start up after failure of firmware update, and then firmware update cannot be performed again can be solved.

Description

technical field [0001] The invention relates to a cabinet, in particular to a cabinet with multiple cabinet management modules and a firmware update method used in the cabinet. Background technique [0002] Generally speaking, multiple servers can be set in one server rack (Rack), and a rack management controller (Rack Management Controller, RMC) is also set up. The manager of the cabinet can connect to the servers through the RMC to collect information about the servers and control the servers. [0003] The RMC belongs to a System on Chip (SoC), which itself has a memory and needs to be booted by executing firmware. Therefore, similar to the central processing units (Central Processing Unit, CPU) in these servers, the manager of the cabinet needs to update the firmware of the RMC from time to time. [0004] Generally speaking, the RMC can automatically update the firmware used after receiving the firmware update file. However, if it is accidentally interrupted during the ...
