Firmware updating method
A firmware updating method in just a bunch of disks includes the following blocks. A motherboard is coupled to a first primary storage extension chip or to a second primary storage extension chip. The first primary storage extension chip and the second primary storage extension chip are coupled to each other. At least one secondary storage extension chip is coupled to the first primary storage extension chip. At least one secondary storage extension chip is coupled to the second primary storage extension chip. A signal sent to the first primary storage extension chip or to the second primary storage extension chip by the motherboard causes firmware of each storage extension chip to be updated.
1. A firmware updating method comprising:
coupling a first primary storage extension chip or a second primary storage extension chip to a motherboard;
coupling the first primary storage extension chip to the second primary storage extension chip;
coupling at least one secondary storage extension chip to the first primary storage extension chip;
coupling at least one secondary storage extension chip to the second primary storage extension chip;
sending a signal to the first primary storage extension chip or the second primary storage extension chip by the motherboard;
updating a firmware of the first primary storage extension chip and the second primary storage extension chip; and
updating each secondary storage extension chips by the first primary storage extension chip or the second primary storage extension chip;
wherein when sending the signal to the first primary storage extension chip, updating the firmware of the second primary storage extension chips by the first primary storage extension chip and updating the firmware of each secondary storage extension chips which is coupled to the first or second primary storage extension chips by the first primary storage extension chip, and when sending the signal to the second primary storage extension chip, updating the firmware of the first primary storage extension chips by the second primary storage extension chip and updating the firmware of each secondary storage extension chips which is coupled to the first or second primary storage extension chips by the second primary storage extension chip.
2. The updating method of claim 1 , further comprising driving a flash of each storage extension chip update by the firmware.
3. The updating method of claim 1 , wherein the first primary storage extension chip and the second primary storage extension chip are redundant.
4. The updating method of claim 1 , wherein the at least one secondary storage extension chip coupled to the first primary storage extension chip is redundant to the at least one secondary storage extension chip coupled to the second primary storage extension chip.
5. The updating method of claim 1 , wherein each secondary storage extension chip is coupled to a hard disk drive to collect information of the hard disk drive.
6. The updating method of claim 1 , wherein the first primary storage extension chip and the second primary storage extension chip are configured to collect information of the at least one secondary storage extension chip.
7. The updating method of claim 6 , wherein the information is temperature and voltage.
8. A firmware updating method comprising:
coupling a first primary storage extension chip to a second primary storage extension chip;
coupling at least one secondary storage extension chip to the first primary storage extension chip;
coupling at least one secondary storage extension chip to the second primary storage extension chip;
sending a signal to the first primary storage extension chip or the second primary storage extension chip; and
updating a firmware of the first primary storage extension chip and the second primary storage extension chip, and updating each secondary storage extension chips by the first primary storage extension chip or the second primary storage extension chip;
wherein when sending the signal to the first primary storage extension chip, updating the firmware of the second primary storage extension chips by the first primary storage extension chip and updating the firmware of each secondary storage extension chips which is coupled to the first or second primary storage extension chips by the first primary storage extension chip, and when sending the signal to the second primary storage extension chip, updating the firmware of the first primary storage extension chips by the second primary storage extension chip and updating the firmware of each secondary storage extension chips which is coupled to the first or second primary storage extension chips by the second primary storage extension chip.
9. The updating method of claim 8 , further comprising driving a flash of each storage extension chip update by the firmware.
10. The updating method of claim 8 , wherein the first primary storage extension chip and the second primary storage extension chip are redundant.
11. The updating method of claim 8 , wherein the at least one secondary storage extension chip coupled to the first primary storage extension chip is redundant to the at least one secondary storage extension chip coupled to the second primary storage extension chip.
12. The updating method of claim 8 , wherein each secondary storage extension chip is coupled to a hard disk drive to collect information of the hard disk drive.
13. The updating method of claim 8 , wherein the first primary storage extension chip and the second primary storage extension chip are configured to collect information of the at least one secondary storage extension chip.
14. The updating method of claim 13 , wherein the information is temperature and voltage.
