the chip unit is further configured to load the system image file in the memory unit, and is configured to start the at least one ARM core board.

6. The ARM server of claim 5, wherein the chip unit is further configured to send working data of the at least one ARM core board to the storage server through the network card unit, so that the storage server stores the working data.

7. The ARM server of claim 5 or 6, wherein the network card unit is connected with the storage server through an Ethernet.

8. A data update method performed by an ARM core board in an ARM server of any one of claims 1-7, the method comprising:

acquiring a program updating instruction from a substrate management controller of the ARM server;

and updating the starting bootstrap program in the ARM core board according to the program control instruction.

9. The method of claim 8, wherein the updating the boot loader in the ARM core board according to the program control instructions comprises:

and under the condition that the chip unit is in a power-off state, updating the boot program according to the updating data included in the program updating instruction.

10. The method of claim 8, after updating the boot loader in the ARM core board according to the program control instructions, further comprising:

under the condition that a chip unit is in a power-on state, loading the boot program for hardware initialization of the ARM core board;

and under the condition that the hardware initialization of the ARM core board is completed, acquiring a system image file from a storage server, and loading the system image file for starting the ARM core board.

11. The method of claim 10, wherein obtaining the system image file from the storage server comprises:

generating a file request according to the identification information of the ARM core board, and sending the file request to a storage server;

and acquiring the system image file matched with the identification information from the storage server.

12. The method of claim 10, further comprising, after loading the system image file for booting the ARM core board:

and acquiring the working data of the ARM core board, and sending the working data to the storage server to enable the storage server to store the working data.
