The technical field to which the invention belongs is particularly applicable. The present invention relates to a magnetic disk array system and a monitoring method for a magnetic disk array system for a network storage device. The previous technology was constrained by the rapid growth of the Internet and the consequent huge data traffic. The use of secure, reliable, and efficient network storage devices has become information technology (Information Technol0aV, ττ The trend of "Noi〇gy 'IT) industry in Benlu. This type of network storage device is, for example, a network attached storage device (Network Attached Storage, NAS), a storage device area network (SAN), or a multi-disk array (Redundant Arrays). f

Independent D1Sks (RAID) servers generally use a disk array device with a disk fault tolerance function. In the disk array device, in addition to the disk drive, it usually includes: a power supply device, a fan device, and other peripheral devices such as a warning light. In the operation of the magnetic array equipment, it is usually necessary to monitor (monitor) the operating status of each device so that the system or maintenance personnel can handle the conditions generated by the device.

Bu, first refer to Figure 1, which is a schematic diagram of internal monitoring of each device in the conventional disk array device. The control device i 0 0 is a device that monitors each device, usually a single control chip; the peripheral devices in the figure J include, for example, a plurality of disk drives 111, a fan module 131, a power supply group 141, and a warning light 113; Usually each disk drive and peripheral device has its own connector
